You are Inspector Arthur Vance of Scotland Yard, and ten cases are
waiting on your desk.

Detective Casebook is a hand-drawn mystery game about looking carefully and
thinking clearly. Every room is a crime scene to be reconstructed piece by piece
— and every case ends with you naming a suspect and being right, or being wrong.

SEARCH THE SCENE
Forty rooms across ten cases, each one drawn by hand. Objects are missing from
every scene; find where each belongs and restore the room to what it was the
night of the crime. There is no timer. Take as long as you like.

READ WHAT YOU FIND
Rooms give up evidence — a jammed flue lever, a torn letter of disinheritance, a
trail of frost across a solarium floor. Each is recorded in your casebook with
what it means, not just what it is.

BUILD THE CASE
The Mind Place is your deduction board. Four questions per case, four pieces of
evidence that answer them. Connect the right fact to the right question and the
picture comes together. Connect the wrong one and nothing happens — the board
will not flatter you.

MAKE THE ACCUSATION
Establishing the facts is not a verdict. You still have to name somebody. Charge
the right person first time and the case closes clean; charge the wrong one and
you are told so plainly, without being told who did it. The answer is never
handed over.

TEN CASES
I The Frostbite Manor Murders — a cold night, an infant alone, a lord vanished
II The Grand Theatre Poisoning — the soprano collapses mid-aria
III Blood on the Orient Line — a locked sleeper car in the Alps
IV The Clockmaker's Alibi — an impossible explosion where time stood still
V The Curse of the Nile Pharaoh — a tomb mask swapped during a blackout
VI The Venetian Masquerade Murder — a poisoned goblet at Carnivale
VII The Clockwork Automaton of Vienna — a machine kills its own creator
VIII Midnight at Raven's End — a keeper gone, the beacon burning green
IX The Casino Royale Heist — three wheels rigged to strike zero at once
X The Final Dossier — the syndicate unmasked inside Scotland Yard itself

THE LONDON GAZETTE
A hundred questions drawn from the cases themselves, ten per chapter, and never
about a case you have not yet opened. Nothing is spoiled.

THE FORENSIC LAB
Dust a print and compare it against the file. It will rule one innocent suspect
out. It will never tell you who did it — that is your job.
