Every case is real work. Every clue is fair. Every book has exactly one answer.

Casebook House publishes puzzle fiction: stories you do not just read, but solve. Each book is a cold case, told through letters, statements and old records, with a register of suspects and a trail of evidence that leads to one name.

An Edmund Hale Cold Case, No. 1

The Harbor Master's Ledger

Somebody in Porthgrey got away with murder. For seventy-three years, the only proof lay hidden in an attic.

A story worth solving.

Letters, witness statements, a ferry ledger and a town register: every case is told through the documents a detective would really hold.

Clues that play fair.

Every clue is tested by software before a book goes to print. Each one is needed, none of them is a trick, and exactly one suspect survives.

Built for the evening.

A pencil, a highlighter and a pot of tea. Checkpoints and hints are there when you need them, and never when you don't.
