Murder Mystery Game Free Printable: How to Judge One, and How to Print It Properly

Straight Answers

A murder mystery game free printable is only free until you press print. Then it costs you paper, ink, and — the expensive one — an evening, whether or not the case turns out to be any good.

That's not an argument against free printables. Plenty are worth printing. It's an argument for spending five minutes checking one before you commit thirty pages of paper and a Saturday night to it, because the checks are quick and the failure is expensive.

This is a practical guide to both halves: how to tell whether a printable mystery is worth your printer, and how to actually print one so it looks like evidence rather than like a handout.

What a free printable mystery usually is

Almost all of them fall into one of four groups, and knowing which you've got tells you what kind of evening to expect.

TypeWhat's in the downloadWhat the evening is like
Character role-play kitCharacter sheets, secret instructions, a host script, round timings.Performance. Guests play people. Fun with confident groups, awkward with quiet ones.
Clue-card gameA page of cards to cut out, each with a fact. Distributed and combined.Fast, light, closer to a logic puzzle than an investigation. Often good with children.
Publisher sample caseA genuine short case file, given free in exchange for an email address.The most representative preview of what a paid case is actually like.
Evidence packDocuments — statements, records, photographs, financials — with no script.Real investigation. Rare as a freebie, because it's the most expensive kind to write.

The five-minute check before you print thirty pages

Open the PDF. Don't read it properly — you don't want to spoil it. Just check these five things, all of which are visible from skimming.

  1. Count the suspects, then count the ones with a real motive. If one character's motive is loud and the others are decorative, your guests will spot it inside twenty minutes. You want at least three people who all look genuinely capable of it.
  2. Find the solution page and read only the culprit's name. Then ask yourself: is there any single document in this pack that would give that away on its own? If yes, the case is a reveal wearing an investigation's clothes. This is the fastest quality test that exists and it takes about ninety seconds.
  3. Look at how full the pages are. A page carrying one short paragraph in the middle of white space is telling your players that whatever is on it matters, before they've read a word. Layout becomes an accidental hint system. Dense pages make people work out which line matters, which is the actual activity.
  4. Check whether anything is labelled as optional. "Bonus lead — optional" is a well-meaning kindness that destroys misdirection: telling a player a thread is skippable tells them it doesn't matter, which is the exact opposite of what a red herring needs.
  5. Check the page count against the play time claimed. A four-page download promising a three-hour evening is promising an evening of you improvising.

Printing it properly

The gap between "printed evidence" and "a stack of photocopies" is smaller than you'd think, and most of it is decisions rather than equipment.

Paper

Ordinary 80gsm office A4 is genuinely fine for most of the pack, and there's a case for it being better — real office documents are printed on cheap paper. Where it's worth upgrading is the handful of items that are meant to feel like objects rather than paperwork: a handwritten note, a photograph, a torn scrap. Those benefit from something heavier, around 120gsm or above, or from photo paper for anything that's meant to be a print.

Colour, and when it doesn't matter

Print photographs, security stills and anything with a coloured stamp or letterhead in colour. Print everything else in greyscale without guilt — most institutional documents are black on white in real life, and you'll halve your ink bill. If a case is designed well, colour carries atmosphere, not information.

Single-sided, always, for evidence

This is the one rule we'd argue for hardest. Duplex printing saves paper and ruins evidence games, because players sort documents into piles on a table and a double-sided page can only be in one pile. Print the case file single-sided. Print the rules or the intro booklet double-sided if you like.

Cut things out before your guests arrive

Anything meant to be a separate object — a card, a scrap, a slip — should already be separate when the evening starts. Handing someone a sheet of A4 with a dotted line on it is handing them a craft project.

What it actually costs

A full A4 page of text uses somewhere around 8–14% ink coverage. A thirty-page single-sided evidence pack is therefore, in home-printing terms, a few pages of photographs and a lot of text — a modest amount of toner and about a third of a ream. Cheaper than a print shop for one copy; more expensive if you want six copies for a group, at which point a local print shop becomes worth the trip.

One genuine reason to prefer a print shop: laser output on plain paper looks far more like a real document than inkjet does, because real documents are laser-printed. If your home printer is inkjet and you want the found-object effect, a shop costs very little and buys quite a lot.

What paid print production adds

Since this post is being honest about free options, it should be equally honest about what the money goes into on our side. Print production is its own build phase for us, and most of it is invisible until it's missing.

  • Page density is a design rule, not an accident. Every page is filled — with clues, with true-but-irrelevant detail, and with the ordinary furniture a real document has: continuation sheets, cc chains, standard terms, ledger rows either side of the one that matters. We audit ink coverage across a finished pack precisely because a sparse page is a hint we didn't mean to give.
  • Filler that is true but irrelevant, never false. If a player chases a detail and it goes nowhere, that has to be because the fact didn't matter — never because the document lied. False filler turns misdirection into unfairness, and it's the specific thing that goes wrong when padding is invented at layout time to fill a gap.
  • Every character gets their own handwriting. If two handwritten items in a case share a font, that's two different people with identical handwriting, and someone will notice.
  • The rendered file gets verified, not just previewed. The engine we use to produce PDFs has confirmed silent-failure modes — certain combinations of effects drop content with no error at all. A page that failed and a page that's meant to be light look identical on screen, so finished packs get checked at pixel level, and QR codes get decoded from the rendered PDF rather than from the source that made it.
  • Numbers are computed, not estimated. Running balances, timestamps, travel times, date arithmetic — anything a player could check gets calculated by a script with an assertion attached, because players absolutely do check.

How to Run a Murder Mystery at Home Game (and the One-Hour Test That Tells You If It’s Working)

How To Host

A murder mystery at home game lives or dies on one question, and you can ask it an hour in: does the room still disagree about who did it? If everyone has quietly settled on the same person and is just waiting for the reveal, the game is already over — you're just doing the admin.

Hosting a mystery night at home has never been easier to start and never been easier to get wrong. You can download something in ninety seconds. You can also spend an evening watching six adults read stage directions to each other with increasing embarrassment. The difference between those two evenings has almost nothing to do with price and almost everything to do with structure — which is the useful news, because structure is something you can check before you commit.

This is the practical version: what the phrase actually covers now, which format suits your group, what you genuinely need on the night, and the specific ways these evenings fall apart.

"Murder mystery at home game" covers three very different evenings

The term has stretched to cover formats that share a genre and nothing else. Buying the wrong one for your group is the single most common way the night goes flat, so it's worth being precise.

FormatWhat players actually doSuits
Character role-play (the classic murder mystery party game)Each guest is assigned a character with secrets, and reads or improvises through timed rounds. One person is secretly the culprit — sometimes even they don't know at the start.Confident, extroverted groups of 6–12 who want a dinner-party performance more than a puzzle.
Case file / evidence packEveryone gets the same body of evidence — statements, records, photographs, financials — and works out the answer by reading and cross-referencing.Groups of 1–6 who want to actually deduce something. Works solo. No acting required.
Hybrid (evidence plus digital gates)A printed evidence pack whose clues unlock real login screens in a browser — an inbox, a bank portal, an archive — holding the next layer of the case.People who want the physical satisfaction of paper and the reward loop of actually getting into something. This is what we build.

The mismatch to avoid: buying a role-play kit for a group of four introverts, or an evidence pack for ten people who came to be entertained. Both are good products in the wrong room.

The one-hour test

Here is the test that separates a mystery from a costume party with a plot attached. An hour in, with roughly half the material read, can more than one person in the room make a serious case for a different suspect?

If yes, the game is working. Everyone is holding partial information, everyone has a theory, and the remaining evidence has real work to do. If no — if the group converged on one name early and the rest of the evening is confirmation — then the game handed the answer over and dressed the rest up as investigation.

This is not a subtle failure. It is the most common one. It happens because writing three genuinely convincing suspects is several times harder than writing one culprit and two names, and it is invisible to the person who wrote the case, who already knows the answer and cannot un-know it. We wrote about that specific problem separately, because it is the thing our own design rules exist to prevent.

The practical version of the rule we build to: could someone read any single document in the pack and confidently name the culprit? If yes, the case fails, no matter how good the writing is.

What you actually need on the night

Less than most guides suggest. A murder mystery at home game is one of the cheapest evenings you can host, because the production budget went into the writing rather than into components.

  • A printer, or a print shop. Home laser or inkjet on ordinary A4 is fine for almost everything. See our guide to printing a mystery at home for what actually matters and what doesn't.
  • A table big enough to spread out. This matters more than people expect. Evidence games are spatial — people sort documents into piles, and piles need room. A coffee table for four is tight; a dining table is right.
  • One phone, tablet or laptop if the case has digital elements. One between the group is enough, and passing it around is part of the fun.
  • Two to three hours, uninterrupted. Not a hard rule, but mysteries do not survive being paused for forty minutes while food is served. Eat first, or eat while you read.
  • Somebody willing to write things down. Not a host, not a game master — just a person with a pen who tracks who claimed to be where. Half the pleasure of these evenings is watching that page fill up.

What you do not need: costumes, a script, an app, an account, a subscription, or a designated narrator. Some formats use them. None of them are required for a good evening.

The four ways these evenings actually fail

1. The reveal card

In some role-play kits, one guest opens an envelope at the start telling them they are the murderer. That player now has nothing to discover — they spend the evening managing everyone else's discovery instead of having an evening. If you're using a role-play format, look for one where the culprit is determined at the end, or where even the guilty player has something left to find out.

2. The one obvious suspect

Covered above, and worth repeating because it is so common: if one character's motive is loud and everyone else's is decorative, your guests will spot it in the first twenty minutes and be polite about it for two hours.

3. The unfair clue

The opposite failure. A solution that depends on noticing a detail in the corner of a photograph, or on knowing something the pack never tells you, produces a room full of people who feel cheated rather than outwitted. The distinction that matters: a good mystery should be hard to assemble, not hard to notice. Our own working rule is that at most one link in any chain of reasoning may depend on spotting something visual — the rest has to be plain readable text a careful person will certainly find.

4. Nobody has to change their mind

The best moment in one of these evenings is when someone who was certain has to publicly abandon a theory. If the case never forces that — if the evidence only ever adds to one picture rather than demolishing another — the night is pleasant but not memorable. Misdirection is not a decoration on a mystery. It is the mystery.

Solo, couple, dinner party or team

Evidence-led cases scale down in a way that role-play cases can't. One person with a case file and a pot of coffee is a genuinely good evening — arguably the purest version of it, since nothing gets solved by committee. Two people is our most common play pattern. Four to six around a table is the sweet spot for argument.

Above about eight, an evidence pack starts to strain: there is only so much paper to go around and quieter people stop reading and start listening. That is the point where a role-play dinner party kit genuinely is the better tool, and we'd rather say so than sell you the wrong thing.

If your group can't get to the same table at all, that's a different problem with a real answer — see running a murder mystery at home online.

Before buying anything, it's worth knowing what the free end of this genre actually offers — some of it is genuinely excellent. We laid it out, with links and no email gate, in the guide to free murder mystery games.

A Table Set for Two

Step Into the Story

She waited at a table set for two. He never came. Three days later, it's not a bad date anyone's talking about any more — it's a missing person.

Sophie Callahan had been talking to a match called "Daniel M." for four months on an app called Matchlight — long enough to feel like she actually knew him, long enough to finally agree to meet in person. She picked the venue, Amara Wine Bar, showed up on time, ordered for two, and waited. Her messages stopped getting replies mid-sentence. Daniel never appeared.

Three days later, her sister reports her missing. Her phone goes straight to voicemail. Her car is still sitting in the wine bar's car park, exactly where she left it.

Asked to look quietly, before anyone panics officially

The wine bar's owner knows you're good at puzzles, and she'd rather have someone she trusts poking around than a police report she can't take back. So she hands you what she's got — Sophie's message history, a few things her sister's shared, and a growing list of people who might know more than they're saying — and asks you to find out what actually happened before this becomes a story nobody can control.

Here's what makes this one different from the mystery you think you're solving: unmasking "Daniel" isn't the ending. It's the halfway point. Who he really is explains why he never showed up — it doesn't explain who Sophie actually ran from.

More than one person had a reason to be there that night

There's the ex-boyfriend who's been a little too present since the break-up. There's a coworker whose attention had already started to feel like a problem before any of this happened. There's a regular at the wine bar who asked Sophie out once and didn't take the no especially well. And there's whoever "Daniel M." really is — a person who, it turns out, was never being entirely honest with Sophie about a great many things.

Every one of them has a real motive. Only one of them was actually standing outside that wine bar when Sophie ran.

What you'll actually be doing

You're working through a genuine message export, a set of screenshots, receipts, and a couple of accounts that don't unlock until you've earned the right password from something else in the file entirely. This one's built to be worked through as a pair — trade theories, argue about who's lying, and don't assume the obvious answer just because it's the one every dating-show plot would give you.

Format:
Solo with a coffee, a date night, a dinner-party challenge, or a team-building exercise.
Typical solve time:
90–120 minutes for the core case.
Digital gate:
A full dating-app inbox to unlock and read properly, not just skim.
The catch:
At least three people genuinely worth suspecting — plus a couple of thinner leads that exist purely to slow you down.

By the end, you'll need to say — clearly, and with evidence — who actually confronted Sophie outside that wine bar, what happened in the moments after, and why. Genre instinct will point you at the obvious name. The file won't let you stop there.

If you are working out which kind of case suits your group, start with how to run a murder mystery at home.

Everything you need arrives as a printable evidence packet plus a real, working dating-app login — no spoilers here, just the file.

The Show Must Go On — Except for the Man Who Wrote It

Step Into the Story

Opening night of the most anticipated production in years. A director's long-awaited comeback. And a counterweight that fails during intermission, on a rigging line that had been inspected and cleared that very same morning.

"The Nightjar" was supposed to be Gabriel Thorne's return — his first major work since a public flop nearly ended his career six years earlier, and the most talked-about opening in the city all season. He was found backstage shortly after intermission began, struck by a falling counterweight from the fly system above the stage. A tragic accident, on paper. Except the venue's own safety officer has already flagged something that changes everything: that exact line was checked and cleared that morning. Rigging doesn't fail on its own, hours after someone confirmed it was fine.

This time, it's not a favour — it's a case number

You're not being asked quietly on the side by someone who'd rather keep this out of the papers. You're detectives with a real provincial Serious and Violent Crimes Unit, assigned a genuine case docket the moment that inspection log came to light. Search warrants, subpoenaed records, full authority — and a file that's going to the National Prosecuting Authority if what you build actually holds up.

Thorne was controlling, meticulous, and difficult in exactly the way that made him dangerous to somebody. Something he found in the days before opening night got him killed. Working out what that was is most of the job.

Three people, three logins, and a killer who isn't the obvious name

There's the production's producer, who has a great deal riding on this show and a lot to lose if certain numbers ever get properly audited. There's the lead actress — Thorne's former protégée, publicly and bitterly split from him weeks before opening — who every instinct in the room will point at first. And there's an uncredited co-writer with the oldest, most sympathetic grievance in the entire case. Add a rigging technician, a critic, and a distant relative, and you've got a full backstage's worth of people who all had a reason to want Gabriel Thorne gone.

This is deliberately our most demanding case yet — three fully-developed suspects, three separate accounts to get into, and a killer we wrote specifically to be the least satisfying answer in the room. If you're chasing the first name that feels right, you're chasing the wrong one.

What you'll actually be doing

You'll be working warrant access into two accounts and public access into a third, checking a call platform's own session log against an alibi that looks airtight until you check it minute by minute, and cross-referencing old production credits to spot a pattern nobody was supposed to notice. Every login is earned from something you found on paper first — nothing is handed to you.

Format:
Solo with a coffee, a date night, a dinner-party challenge, or a team-building exercise.
Typical solve time:
90–150 minutes — our most demanding case yet.
Digital gates:
Three separate accounts, warrant and public access alike.
The catch:
Three fully-developed suspects, plus real minor leads — no thin decoys.

By the end, you'll need to state — clearly, with a docket that would actually hold up — who is responsible, what happened during intermission, why they needed Thorne gone by that specific night, how they had the knowledge to do it, and why the two people you'll suspect first are not, in fact, guilty.

Curious how three suspects are built to stay standing this long? We wrote about it in why every suspect has to earn your suspicion.

Everything you need arrives as a printable case file plus three real, working login screens — the same standard our actual Digital Forensics unit would use.

The Story That Killed a Company

Step Into the StoryComing Soon

The story ran on the front page. The correction ran on page two, three months later. In between, a company died.

Kesterley District Council put its waste and recycling contract out to tender for the first time in fourteen years. The long-standing incumbent lost. The contract went to a smaller family firm, run by a woman named Frances Aubrey, on a bid nine per cent cheaper — the kind of result that should have been a good news story.

Six weeks before the new contract was due to start, The Kesterley Clarion ran a front-page exposé: leaked council correspondence and a payment record that, the paper said, proved Frances Aubrey had bought the contract. The council opened an investigation. The new firm's lender pulled its funding within nine days. A firm mid-way through fitting out vehicles and a depot, suddenly with no financing and no ability to earn, doesn't survive that. Ninety-one jobs went. The council quietly reverted to the old contractor — which is the detail almost nobody notices, and the one that matters most.

Three months later, the Clarion printed a correction: the leaked material couldn't be authenticated, and the paper accepted the allegations were unfounded. Frances Aubrey sued for defamation. And that's where you come in.

You're working for the paper that might have ruined her

You're forensic investigators, instructed by the solicitors defending the Clarion, which is fighting this on a public-interest defence. Your job is to reconstruct exactly what happened to those leaked documents — because the defence, and the newspaper's own insurance cover, both turn on one question: was the newsroom fooled, or was it complicit?

That's not a comfortable position to investigate from. You're working for a client whose survival depends on what you find, and there's a real chance what you find sinks them anyway. Nothing here is a crime scene. It's disclosure — committee minutes, tender sheets, weighbridge tickets, newsroom copy, an insurer's own claim file — produced by people who all had reasons to shape what they handed over.

The forged documents are sitting right in front of you

Here's the part that makes this case genuinely different: you don't read a description of the forgery. You get the actual leaked package, exactly as the newsroom received it — and half of it is completely real. A genuine payment, to a genuine firm, for genuine work, made years before any of this started. The other half was built to sit next to it and borrow its credibility. Working out which is which, and who could possibly have built it, is the entire investigation.

Along the way you'll meet a reporter who's been suspended over a story that wasn't entirely hers to get wrong, an editor who cut a verification step that exists for exactly this situation, a councillor with a real and properly declared financial connection to one of the leaked documents, and a council compliance officer twenty-two years into a job nobody ever looks at twice. Every one of them can explain a piece of what happened. Only one of them built the forgery.

What you'll actually be doing

This one doesn't ask you to read someone's private inbox — it asks you to search institutional records the way a real forensic accountant would. You'll be comparing a document-reference format against a system migration date to catch an anachronism nobody meant to leave behind, cross-checking a company register against a client's own ledger, and doing arithmetic on a weighbridge ticket book that looks perfectly ordinary until you sort it by load type.

Format:
2–6 players, explicitly solo-viable.
Difficulty:
3/5 — plenty to chase, no single thread requires holding another in your head.
Digital gates:
Three institutional records systems to search, not just an inbox to read.
The catch:
Identifying who's responsible and proving why are two different jobs. The case isn't solved until both are done.

By the end, you'll need to say — clearly, and with the paperwork to back it up — who built the leak, how it survived a legal read on deadline, and why. Get the who right and the why wrong, and the case still doesn't hold.

This case is in final production. Subscribe below and we'll tell you the day it lands — no other mail, ever.

The Letter She Left Sealed

Step Into the StoryComing Soon

Your mother said she didn't do it. She was right, and she knew who did.

Seventeen years ago, the sculptor Anton Vael died at Marrow Point — the family's studio and smallholding on South Africa's West Coast — poisoned during a weekend gathering with the people closest to him. His wife, Rosalind, was convicted eleven months later, on evidence that was largely circumstantial but for one damning detail: she was seen washing out the decanter believed to have carried the poison. She died in custody, fourteen months into her sentence.

You were ten years old. You're turning twenty-eight now — the exact age your mother was written into her own trust, the age she was when she married your father. That birthday unseals a personal archive she left behind, and the family solicitor hands it to you along with the rest of the estate. Inside is a letter, written in the months before she died, stating plainly that she didn't do it. And that she knew who did.

This time, nobody hired you

Every previous Exhibit A case has put you on the outside of the story — a consultant, an investigator, someone brought in to look at other people's lives. Not this one. This is your father, your mother, and your own name on the birth certificate.

The family's solicitor is honest with you about what you're actually holding: a route, not a guarantee. A petition under section 327 of the Criminal Procedure Act, addressed to the Minister of Justice, presenting new evidence that materially affects a conviction — a mechanism written for a living petitioner, with essentially no precedent for a case like yours. Your job is to assemble the evidence that petition needs. The report you eventually file isn't a police report or an insurer's finding. It's the substance of your own affidavit.

Five people were at Marrow Point that weekend. All five are still alive.

There's your father's business partner, who'd discovered a discrepancy in a foundry ledger days before your father died and had a great deal to lose if it ever surfaced. There's your mother's half-sister, mid-argument with your father that same weekend over a family cottage neither of them would back down on. There's the estate's longtime manager, who handled the household accounts and never quite explained a discrepancy of her own. And there's a woman who modelled for your father for three years — present at Marrow Point, and, as far as the original investigation ever established, entirely unremarkable.

Nobody in this file is a stranger. That's what makes reading their statements seventeen years later so much harder than it should be.

What you'll actually be doing

You're working through your mother's own unsealed email account, your father's studio business archive, and the original defence file itself — three separate archives, each released to you specifically because of who you are, not because of a badge or a warrant. Somewhere in a foundry pour log, an edition number that was supposed to mean something stops adding up. Somewhere in a caterer's schedule and a family photographer's contact sheet, a twenty-minute window narrows to exactly one person. And somewhere in your mother's own words, never sent to anyone, is the thing the original trial never had a way to hear.

Format:
2–6 investigators, solo-viable.
Difficulty:
4/5 — dense rather than sprawling. Fewer pages, more packed into each one.
Digital gates:
Three sealed family and legal archives, unlocked on the terms of a trust, not a warrant.
The catch:
The person who convicted your mother wasn't wrong that something happened in that kitchen. They were wrong about what it meant.

By the end, you'll need to say — clearly, and with enough to actually put in front of the family's solicitor — who poisoned your father, what happened, and why. Your mother already told you she knew the answer. She just didn't get to say it in a way anyone believed.

This case is in final production. Subscribe below and we'll tell you the day it lands — no other mail, ever.

Six People, One Road

Step Into the StoryComing Soon

Six people. One road. It went at midnight.

Ardenfell Observatory sits on an upland plateau, ninety kilometres from the nearest town, reached by a single road that crosses a shallow river at a low-water ford. Six people were there for a three-night observing run. On the second night, the rain didn't stop, the ford went under, and the only way in or out of Ardenfell disappeared with it.

Somewhere around 02:00, Dr. Miriam Hallam — a revered astronomer on what everyone knew was her last observing run before her health ended her career — fell roughly seven metres from the exterior catwalk of the main dome onto the concrete below. It should have been a tragic accident on a dark, badly-lit walkway. Then the site manager's own report mentioned a catwalk gate that shouldn't have been open, and a witness account that didn't quite hold together.

It was forty hours before the road was passable again and anyone official could reach the site. Forty hours, six people, one building, and — for at least one of them — the growing certainty that somebody in that room had probably killed her.

Forty hours is a long time to get your story straight

You're detectives with the Hartsmere Constabulary Major Crime Unit, brought in the moment a probable accident became a suspected homicide. But this isn't a scene anyone preserved for you. The first accounts were taken over a satellite phone by a non-police first responder, and by the time you actually arrive, six people have had forty hours together to talk, to tidy, and — whether they meant to or not — to align.

What you get instead is something better than an untouched crime scene: a set of very human, very self-interested statements, and the one category of witness at Ardenfell that had no motive and no forty hours to reconsider anything — the observatory's own machines. Dome rotation logs. Instrument exposure logs. A power event log. A long-exposure camera pointed at the sky the whole time. None of them can lie, and none of them are on anyone's side.

Everyone at Ardenfell had a reason to be up there

There's a visiting instrumentation scientist commissioning new equipment, with a professional history nobody on site actually knows. There's a postdoctoral researcher whose entire career is riding on this run's data, and who's worked out something about Miriam he's not saying out loud. There's the site manager — twenty years at Ardenfell, the only person who holds a key to that catwalk, and the only one who knew exactly which section of handrail was unsafe. And there's a technician who lied about being asleep, and a science journalist Miriam had threatened to freeze out of a story that mattered to her.

Opportunity doesn't help you here — everyone on site had it. This one gets solved on means, motive, and the moment a person's own account stops matching what a machine wrote down.

What you'll actually be doing

You'll build a reconstruction grid — six names down the side, the hour that matters across the top — and fill it in twice: once from what each person says, and once from what the site's own systems recorded. Somewhere in that grid is exactly one cell where those two versions cannot both be true. You'll need warrant access into the site's own mail system, a production order for an off-site university record no one at Ardenfell could have touched, and a password assembled from two documents that, on their own, have nothing to do with this observatory at all.

Format:
Built for 4–8 investigators.
Difficulty:
5/5 — our most demanding case yet.
Typical solve time:
3–4 hours.
Digital gates:
Three separate systems, accessed by warrant and by production order.
The catch:
Everyone had opportunity. The case turns on the one thing that can't be talked around.

By the end, you'll need to state — clearly, and against a docket that either holds or doesn't — who is responsible, what actually happened on that catwalk, and why. Rule out the obvious answer first. It's there for a reason.

Ninety Seconds of Darkness, One Missing Masterpiece

Step Into the Story

Three hundred guests, black tie, the press in the room, and a painting nobody had seen in decades finally about to be unveiled. Then the lights go out — and when they come back, the frame is empty.

The Halstead Gallery had spent months building up to this exact moment: the unveiling of The Nightingale's Hour, a masterwork by Marguerite Colville, presumed lost for decades and only recently authenticated. It was meant to be the museum's biggest night in years. Instead, at the precise second the curtain was supposed to rise on the painting, the entire gallery lost power. Ninety seconds later, the lights came back. The curtain rose anyway. The frame was empty.

Called in before this becomes a headline

Director Rosalind Whitfield has one goal: work out what actually happened before the insurers start asking questions she can't answer and before this becomes the story the press runs with instead of the painting itself. So she brings in a set of discreet outside consultants — that's your table — to get to the truth quietly, before anyone official is involved.

Here's the thing worth sitting with before you start pointing fingers: a ninety-second blackout is an oddly specific amount of time to steal anything. It's barely enough to walk into a room, let alone lift a canvas off a wall and disappear with it. Which raises a question the obvious theory doesn't answer — was anyone actually stealing anything at all, or is that the wrong question entirely?

A guest list full of reasons to look elsewhere

There's a rival collector with a long-standing grudge against the gallery. There's a descendant of the artist with his own complicated feelings about how this "rediscovered" piece is being handled. And there's the museum's own conservation team, who had more access to that canvas in the weeks before the gala than almost anyone else in the building.

Every one of them can explain a piece of what happened that night. Only the full picture — the blackout, the painting, and exactly who had the access to arrange both — actually closes the case.

What you'll actually be doing

This one's built for a group to split up properly: four distinct threads — the blackout itself, the painting's own condition, the conservation lab's access records, and the guest list's motives and alibis — meant to be divided into pairs and worked in parallel, then argued over when everyone reconvenes. Half the satisfaction here is watching your own group disagree about what a piece of restoration paperwork actually proves.

Format:
Built for a group of 4–6, split into pairs across four threads.
Typical solve time:
110–140 minutes for the core case.
What you're working with:
Security logs, restoration records, and a guest list that doesn't clear itself.
The catch:
At least three people genuinely worth suspecting — plus a couple of thinner leads that exist purely to slow you down.

By the end, your group needs to be able to tell the Director — clearly, and with the paperwork to back it up — who's responsible, what actually happened during those ninety seconds, and why. It's a more sympathetic story than a straightforward theft would be. It's also a much better mystery.

The Vault Nobody Remembered

Step Into the Story

Every record the bank holds says the same thing: decommissioned, contents none, nothing to see. So why did someone go to the trouble of quietly resealing it during a power cut nobody was supposed to notice?

The old Church Street branch is being cleared ahead of a scheduled redevelopment — the kind of routine, unglamorous work that mostly involves clipboards and dust sheets. Then, in the early hours of 14 June, the night security officer notices something the paperwork can't explain: the vault's inner seal has been disturbed, and carefully put back, during a maintenance blackout that shouldn't have given anyone the chance.

According to every system the bank holds, that vault has been empty since 1994. Officially, there was never anything here worth stealing back. Unofficially, someone was willing to arrange a five-hour power outage to get near it — which means either the records are wrong, or somebody wanted them to look that way for a very long time.

Brought in before anyone official finds out

Lena Marais, the bank's Head of Compliance & Legal, isn't ready to hand this to the insurers or the board — not yet, not until she knows what she's actually dealing with. So she brings in outside help, quietly, and that's where you come in: a set of pre-demolition sign-out slips, a decades-old locksmith's invoice, and a court judgment from 1985 that nobody's thought about in years, all waiting for someone to notice they belong to the same story.

What you're chasing isn't a straightforward theft. It's a secret that somebody has been protecting since long before the vault was ever declared "empty" on paper — and the closer you get, the less that word looks like an accident.

Everyone in this file has a reason to want that vault to stay shut

The Head of Archives has been quietly pulling old personnel files that have nothing to do with her actual job. A young CEO — grandson of a name buried in that 1985 court case — has had his office calling Archives about this exact vault, more than once, including the day of the break-in. A woman with a family grudge that predates all of you has been researching the same history from the outside. And a Branch Operations Manager whose sign-off happens to cover the exact area that was broken into is carrying a kind of stress that colleagues have definitely noticed.

Every one of them has a real reason to be on your list. Only one of them arranged that blackout.

What you'll actually be doing

This is the case that taught us three logins is better than one — you'll be cross-referencing an old locksmith's invoice against a personnel file to reconstruct a password nobody wrote down anywhere, reading through a colleague's actual inbox once you've earned your way in, and reading a real bank statement, transaction by transaction, to find the exact moment somebody's finances stopped adding up. Nothing is handed to you as a conclusion. You have to go and find it, the way an actual investigator would.

Format:
Solo with a coffee, a date night, a dinner-party challenge, or a team-building exercise — this one flexes.
Typical solve time:
60–90 minutes for the core case.
Digital gates:
Three separate logins, each a different kind of puzzle.
The catch:
At least three people genuinely worth suspecting — plus a couple of thinner leads that exist purely to slow you down.

By the end, you'll need to say — clearly, and with evidence — who actually emptied that vault, what they took, why they wanted it, and how they had the access to pull it off. Get any one of those wrong and the case doesn't hold.
