CROSS OUT
WHAT CAN'T BE.

Murder mysteries you solve with a pen. You never guess the culprit — you strike out everyone and everything that cannot be, and see what refuses to fall.

How a case works

Three moves, and the field narrows

CLUE BY CLUE

Open a clue

A clue is a small scene — a sound in the walls, dust that lay unbroken, a key signed out at midnight. Every scene hides one rule.

PEN IN HAND

Strike the impossible

The rule condemns suspects — or the rooms they stood in. Strike them from the register and watch the field of the possible narrow.

THE ARCHIVE

Bring your answer here

When one stands alone, that is your answer. It is printed nowhere in the book — it lives only here, behind the seal.
