CaseFilex: Detective Mystery

Be the detective. Twelve cold cases are waiting on your desk, and each one is a box of real-looking evidence: police reports, witness interviews, phone messages, receipts, door logs, maps, newspaper clippings and medical examiner summaries. No quiz questions and no hidden-object hunts. You read, you cross-check the clues, and you work out who did it.

HOW A CASE WORKS
- Open the case box and read the briefing.
- Study the evidence. Every document has its own look: typed police reports, chat bubbles on a phone, a thermal receipt, a handwritten note, a street map with numbered pins.
- Tap a highlighted detail to pin it to your evidence board. Clues with a time build your timeline in order.
- Mark suspects as suspicious or cleared and keep your own notes on every case.
- When you are ready, make your accusation: name the culprit, the motive and two or three clues that prove it.

FAIR MYSTERIES, ONE CLEAR ANSWER
Every case is solvable from the evidence alone. The red herrings are fair, and the evidence explains them. A wrong accusation tells you how many of the three parts were right and lets you keep investigating. There is no game over. Get it right and the case-closed debrief tells the whole story and shows the proof.

STUCK ON A CASE?
Each case has three hints: a nudge, a pointer and a near-answer. Open them one at a time, only when you want them.

THE COLD CASE FILES
- A cash box taken from a bakery by someone who knew the alarm code
- A 230-year-old violin that vanished during a fifteen minute interval
- An innkeeper's last cup of tea
- A painting swapped for a copy while the gallery was closed
- A warehouse fire and a ferry that never sailed
- A locked vault that opened with the right card and the right PIN
- A burglary on a half marathon route
- One set of footprints in fresh snow
- A radio host who vanished at the cliffs
- A leaked formula and a file full of clocks set to different time zones
- A clockmaker, a stopped clock and a suspicious will
- Two million in gold coins gone from a harbour on a dark night

Cases range from a gentle start to fiendish, rated from one to five magnifying glasses, with an estimated time for each. A good whodunit for fans of crime fiction, logic puzzles, deduction and detective stories.
