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.

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.

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.

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

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.

He Kept Every Secret in Code. Someone Just Stole the Key.

Step Into the Story

Anton Draganov died quietly, of a heart attack, in his own home. Within a week, his private study had been searched and the one thing he never let anyone touch — a lifetime's worth of secrets, kept in a cipher only he was supposed to understand — was gone.

For decades, Anton was one of the region's most careful black-market antiquities dealers: never flashy, never caught, and — it turns out — never entirely honest even with the people who trusted him most. His personal ledger wasn't just old business. It was proof of exactly what he took, and from whom, across a lifetime nobody else ever fully saw.

Not police work — a recovery, and a race

You're investigating for The Provenance Trust, a private cultural-heritage recovery organisation that had been quietly building a case against Anton for years, waiting for the right moment to either prosecute him or negotiate the return of what he'd taken. His death didn't close that file. It may have just made things harder — because whoever has that ledger now has decades of his secrets, and at least one shipment of genuinely stolen antiquities he never actually delivered.

Nobody's died as a result of the theft. Nobody's called the police, and nobody's going to. What's actually at stake is whether a hidden cache of looted cultural property gets returned to where it belongs — or vanishes into the market for good, in the hands of whoever gets there first. That might not be you.

A house full of mourners, and only one who went into the study

The memorial gathering after Anton's funeral brought together everyone who ever had a reason to care what happened to that ledger: a relative back in the country for the first time in years, a business partner of two decades who gave a short, genuine remembrance to the room, and the caretaker who'd managed Anton's house — and, it turns out, spent a great deal of time near that study — for his final eighteen months.

During that fifteen-minute remembrance, with the whole gathering's attention on one room, the rest of the house sat essentially unwatched. Someone used that window. Working out who requires more than a guess — you'll need an alibi, a motive, and an opportunity that actually survives being checked against the minute.

What you'll actually be doing

This is one of our more demanding cases: a genuine substitution cipher to work out for yourself, using a photograph, a shipping record, and one deliberately misleading example designed to teach you the mechanic without handing you the answer. Once you've got it, you'll be applying it to a real coded ledger entry — and reading three separate accounts, one of which was never meant to be found at all.

Format:
Solo with a coffee, a date night, a dinner-party challenge, or a team-building exercise.
Typical solve time:
120–160 minutes — one of our more demanding cases.
Digital gates:
Three separate accounts, one of them locked behind a cipher only you can crack.
The catch:
At least three people genuinely worth suspecting — and an ending that may not feel as clean as you'd expect. That's intentional.

By the end, you'll need to say — clearly, and with evidence — who actually took the ledger during the gathering, what drove them to it, how they had the opportunity in that one specific window, and why the other two names on your list aren't, in fact, responsible.

If you want to judge this one against anything else on the market first, the nine checks in our buyer's guide are the same ones we hold our own cases to.

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.

Why Every Suspect Has to Earn Your Suspicion

Behind the Design

There is a specific failure we design against on every single case: a solver opens the evidence packet, reads two documents, and names the culprit correctly before they have touched half the pack. It happened once, early on. It has not happened since — because we rebuilt the rule that governs every case that follows.

The rule is simple to state and hard to build: every case needs at least three suspects who all remain genuinely plausible until the full picture is assembled. Not one obvious culprit propped up by two thin decoys who fold the moment you look at them. Three real people, each with a real motive, each with something genuinely alarming attached to their name, each requiring an independently checkable fact before you can cross them off. Beyond those three, we add at least two more minor red herrings — smaller, faster to resolve, but still real leads, never throwaway names dropped in for texture.

The test we hold every case to before calling it done: could someone read any single document in the pack and confidently name the culprit? If the answer is yes, the case fails — no matter how good the writing is around it.

A red herring earns its place the same way the real culprit does

"Had a motive, but had an alibi" in two sentences is not a red herring — it is a shrug. Every suspect we build gets the same three-part arc: a real motive, a specific detail that should worry you, and a resolution that only comes from a fact you had to go and find and check yourself, not a line of text telling you they are innocent. If a lead does not earn that much, it does not go in the pack.

Discover, don't state

That connects to something else we hold to on every page: we never state a conclusion when a player could discover it instead. Early on, one of our evidence items said, in plain text, that a suspect had missed two loan payments — a fact handed over for free. The fix was not rewriting the sentence. It was deleting the sentence, and moving that same fact into a bank statement a player had to find the login for and read themselves.

The fact did not change. Who did the work to learn it did. That is the difference between a mystery you read and one you solve.

Nothing in the pack is labelled "optional"

It is tempting to label a thinner lead "Bonus — skip if you are short on time", but that instantly tells a player it does not matter, which defeats the entire point of a red herring. If a thread exists in the pack, it is there to be taken seriously.

And every page — evidence, quick-access cards, the ordinary institutional paperwork sitting between the pieces that matter — carries real content, never a couple of clues floating in white space. A half-empty page is its own kind of spoiler: it tells you where to look before you have earned the answer. A full page makes you do the work of figuring out which line is the one that counts. That is not padding. That is the actual product.

Who, what, and why — never who alone

Naming the right person is not solving the case. Every one of our report screens asks for the who, the what and the why, because a lucky guess and a proved conclusion should not score the same. If you can name the culprit but cannot say what they did or why they did it, the case is not closed — and the screen will tell you so.

How to check this in anything you buy

None of the above is proprietary. It is how fair-play mystery has worked since Golden Age detective fiction, and you can run the same tests on any kit before you spend money on it — open the PDF, find the solution page, read only the culprit's name, then ask whether any single document would have given that away. We put the full checklist in our buyer's guide to murder mystery kits.

If you would rather see the principle from the player's side, how to solve a murder mystery game covers the same ground from the other end of the table.

Every case built to the rules above — three suspects who stay standing, nothing solvable from a single page, and a verdict screen that asks you to prove it.

How to Solve a Murder Mystery Game

Tips & Guides

Most people who get stuck on a murder mystery game are not missing a clue. They are reading the evidence in the wrong order, and arguing before anyone has finished reading.

A good case file is designed so that no single document gives the answer away. That is the whole craft of it — and it means the skill you need is not cleverness so much as method. Here is the method, in the order that actually works.

1. Read everything once before you theorise

The single most common mistake. Someone finds a suggestive detail on page four, says it out loud, and the whole table starts building a case around it before anyone has seen page twenty. From that point on, every new document gets read as evidence for or against one theory rather than on its own terms.

Read the whole pack first. No theories, no accusations. It feels slow and it saves you an hour.

2. Separate what someone claims from what a record shows

This is the distinction that solves cases. A witness statement is not evidence of what happened — it is evidence of what a person chose to say. A bank statement, a call log, an access record, a timestamp: those are different in kind, because nobody wrote them to be read by you.

Keep two lists as you go. What people say. What the paperwork records. The answer usually lives in the first place those two disagree.

3. Build a timeline before you build a suspect list

Take a sheet of paper, put the names down the side and the hours across the top, and fill it in twice — once from the accounts people give, once from what the documents actually establish. Somewhere in that grid there is a cell where both versions cannot be true.

Suspect lists invite you to pick a favourite. Timelines do not care who you like.

4. Chase the boring documents

Everyone reads the dramatic letter. Fewer people read the ledger rows either side of the one that matters, or the third page of a maintenance schedule. Well-built cases hide the load-bearing fact in ordinary paperwork precisely because that is where a real investigator would have to look.

If a document seems too dull to be relevant, that is often the point.

5. Work out why each suspect is not guilty

Flip the question. Instead of hunting for the culprit, try to clear each person properly — and insist on a checkable fact for each one, not a feeling. A suspect you can only clear with "they seemed sincere" is a suspect you have not cleared.

You will usually find there is exactly one person you cannot rule out. That is the answer, and now you can say why.

6. Say the whole answer out loud before you commit

Who, what, and why. If you can name a person but cannot say what they did or what drove them to it, you have guessed. A well-built case will not let a guess score the same as a proof, and being able to state all three is the difference between finishing a case and finishing it honestly.

Read first:
The whole pack, before anyone theorises.
Two lists:
What people claim, and what records show.
Timeline:
Filled in twice — from accounts, and from documents.
Finish with:
Who, what and why — or you have guessed.

Where the digital gates fit

If your case has login screens as well as paper — ours do — the method does not change, but the order matters. A password you have not earned yet is not a puzzle to brute-force; it is a signal that you have not found the document that gives it to you. When you are stuck at a gate, go back to the paper rather than guessing at the keyboard.

And once you are in, read the system properly rather than skimming for the one item you came for. An inbox or an archive is written to be searched, and the thing you were not looking for is often the thing that closes the case.

Practising on something free

The instinct this all trains — treat every alibi as a claim, not a fact, until the paper trail backs it up — is exactly what Golden Age detective fiction was built to exercise. If you want to sharpen it before spending anything, our guide to free murder mystery games lists genuinely free, legal options with no email gate.

And if you are still deciding what kind of evening to run, start with how to run a murder mystery at home. For the design side of the same coin, why every suspect has to earn your suspicion explains what a case is doing to you while you solve it.

Put the method to work on a full evidence packet plus real, working login screens — no app, no account, just you and the file.
