Why Every Suspect in an Exhibit A Case Has to Earn Your Suspicion
There's 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've touched half the pack. It happened once, early on. It hasn't 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 isn't a red herring — it's 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 find and check yourself, not a line of text telling you they're innocent. If a lead doesn't earn that much, it doesn't go in the pack.
Discover, don't state
That last point 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 wasn't 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 didn't change. Who did the work to learn it did. That's the difference between a mystery you read and one you solve.
Nothing in the pack is labeled "optional"
It's tempting to label a thinner lead "Bonus — skip if you're short on time," but that instantly tells a player it doesn't matter — which defeats the entire point of a red herring. If a thread exists in the pack, it's there to be taken seriously, full stop.
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've earned the answer. A full page makes you do the work of figuring out which line is the one that counts. That's not padding — that's the actual product.
Who, what, and why — never who alone
Finally, solving an Exhibit A case has never been about picking the right name from a dropdown. Every report screen checks three things: who did it, what actually happened, and why — and you don't get credit for two out of three. A lucky guess on "who" has never been enough, and it never will be.
None of this is abstract theory bolted on after the fact. It's a framework built from specific mistakes we made, caught, and fixed — and it's the standard every case since has had to clear before we call it finished.
