Short description

Long description

Add a ready-made detective section to your own puzzle books for adults.

Each of the 30 cases fits on one 8.5 x 11 in page: a short crime story set in a manor, a castle, an abbey or a grand hotel, a logic grid, and a list of clues. Readers cross off the impossible pairings, work out which suspect had which weapon and was in which room, and name the killer.

There are 3 levels: 10 easy cases (3 suspects), 10 medium cases (4 suspects) and 10 hard cases (4 suspects plus a timeline from the guest book). Every case was checked by a solver program: the clues lead to exactly one solution, and no clue is unnecessary.

The pack also includes a "How to solve a logic grid" page and 8 solution pages with the full answer table and the killer for every case. Black and white, no logo, no page numbers, at least 0.75 in of margin on every side.

• A "How to solve" page, 30 murder-mystery logic grid cases (one per page: story, grid, clues), 10 easy (3 suspects), 10 medium (4 suspects), 10 hard (4 suspects and a timeline), followed by 8 solution pages.
