Monday, 7 October 1957. Edmund Carrow brings a letter to the post office counter. The flap is rippled: someone has opened it and stuck it down again with flour paste. Find where the letter was opened, and at what time. About 26 minutes: 20 for the puzzles, 6 for the card.

Inside the book

64 puzzles, 7 kinds

Logic grids, word searches, suspect rosters, floor plans, safe codes, ciphers and a codeword. Four different kinds in every case.

Levels 2 to 5

Every puzzle prints its own level and its own minutes, from 3 to 17. About 10 hours of solving in all, by the book’s own estimate.

192 hints, in three tiers

A nudge, a strong hint, then a near answer for every puzzle. The Finale has three of its own.

Answers that show the working

Every answer is followed by the numbered steps that force it. The killer is named only at the very end, on a right-hand page behind a page that tells you to stop.

No apps or websites are needed to play. Pencil, paper and the book are enough.
