How to play

Think like a detective

No trivia, no timers. You get a real case file and one guess. Here’s how it works.

01

Read the briefing

Each case opens with what the police knew on day one, and a single question to answer. Then you open the file.

Statement · Clue 0130 Jun 1910

Her friends go to the police

From: Report, Scotland Yard

John Nash and his wife, the music-hall performer Lil Hawthorne, tell police they are not satisfied with Dr Crippen's story. When they asked him where in California Cora died, his answers were vague. No death notice has come from America, and nobody received a letter from her before she left.

02

Work through the clues

Statements, lab reports, photos, plans, telegrams and newspaper cuttings — in the words of the time, kept short and clear. Some matter. Some don’t.

Make one guess

Your proof

Pick up to three clues. You score for each one that really helped crack the case.

Questions

Good to know

Are these real cases?

Yes. Every case is a real murder that was solved, with a conviction on the public record. The clues are condensed and paraphrased from trial records, inquests, memoirs and newspapers of the time.

Why are some names blacked out?

Where a clue would simply hand you the answer — a name in a telegram, say — we black it out. The detectives didn’t have it that easy either.

Is it graphic?

We never show victims or injuries, and there are no crime-scene photos. Some clues describe what investigators found, in short, factual words — only as much as you need to follow the evidence. These were real people, and each case opens with a note in their memory.

Do I need an account?

No. Your boards, notes and answers are saved in your browser on this device. Clearing your browser data will clear them too.

Can I change my guess?

No — you get one guess per case. Take your time, read everything, and use the board.

How often are new cases added?

Each case takes weeks of research to get right, so new ones arrive as they’re ready. Leave your email on the home page and we’ll tell you when the next one opens.
