Case file

10:15 pm, Blackwood Manor. The Duchess's emerald brooch vanished in the Study.

Exactly one person was in the Study at that moment: the culprit.

The suspects: Felix, the gardener; Cecily, the heiress; Desmond, the butler; Maud, the archivist; Agatha, the cook. Rooms: Study, Kitchen, Conservatory, Library.

Among the five: 1 Liar, 2 Evasive, the rest Honest.

🔎 Evidence on the desk: 🎟️ a ticket stub, 🖋️ a fountain pen. Physical evidence never lies.

🔗 Felix & Desmond: married
Desmond & Maud: married
Felix & Agatha: siblings

Nobody lies about anyone else. The only thing a suspect can hide is where they were.
Honest suspects tell you where they were.
A Liar names the wrong room (never the Study), then sticks to the story.
An Evasive suspect won't say where they were.
The culprit is always a Liar or Evasive. Related suspects know each other's nature.

Suspects

The booth

A crime, five suspects, one of them was at the scene. Find them.

Ring a suspect's 🛎️ to bring them into the booth, then pick a question card. You get 10 questions in all.

Nobody lies about anyone else. The only lie is a Liar naming the wrong room for themselves, and the culprit always has something to hide.
Tap a suspect's name to see what you can ask them before you ring.
🔎 Some days there's physical evidence on the desk (up to two items). Try 🔄 spin, 🔍 zoom or 🧪 the bootleg test on it. Examining an item uses 1 question, once. After that, try the tools on it as often as you like. Evidence never lies.
Cases get harder through the week: easy on Monday, fiendish on Sunday. Play past cases from the 📁 archive.
The notepad fills in hard facts. Pencil in your own deductions.
Stuck? Sergeant Doyle, smoking by the window, will give you a tip, but it costs you a Perfect.
A wrong accusation clears that suspect and you can carry on, but it costs you a perfect solve. 3 charges per case.

🏆 Perfect: at or under par, and you charge the culprit the moment the testimony proves it, first try, no tips. 🎯 Sharp: within 2 of par. ✅ Solved. ❌ Wrong accusation.

Standard is pure deduction: Doyle only speaks up if you ask a question you didn’t need. Casual flags clashing testimony and tells you the moment you have enough. Switch at the top; the result card shows which you played.

Par is what a careful detective needs without knowing any answer in advance. The case report shows that route.

A new case every day. Everyone gets the same one.
