How a case is solved

The suspects' cards for case 11 · The cards
Each suspect says where they were: in an area, in a row, next to a piece of furniture or beside another person. They all tell the truth… except in some of the hard cases, where one of them is lying.
The map for case 12 · The map
Place each suspect: one person per row and per column, as in sudoku. The last free square is where the victim was, and whoever is in the victim's area is the murderer.
The solution to case 1, reasoned3 · The solution
At the back of the book, every case is solved and reasoned step by step: where each suspect was, why, and who the murderer is.

Every chapter, a world. Every case, a new map.

A house, the beach, a barn, an emergency room, a book club, a spa hotel, a museum at night, a Paris apartment building, a night train, a polar station, a ryokan, an excavation in Egypt, a mansion, an ocean liner… and ten bonus cases with animals.

Start knowing nothing

The book opens with a sample case solved step by step: what each card says, how squares are crossed out and how you get to the murderer.

  • The rules on one page, no jargon.
  • The first cases take a few minutes.
  • Difficulty rises chapter by chapter.
  • Tips for experts: the liar and the accomplice.

90 logic and mystery puzzles: a murder, a map and a handful of suspects who tell you where they were. Put each of them on their square and find out who was left alone with the victim.

SUDOKU DETECTIVE combines the sudoku rule with the logic of a whodunit: one person per row and per column. Each suspect tells you where they were (“next to the fireplace”, “in the first column”, “not with Diana”), the general clues narrow down the rest, and when only one free square is left, that is where the victim was. Whoever shares that area is the murderer.

No prior knowledge needed: the book opens with a case solved step by step, and from there the difficulty rises little by little. The first cases take a few minutes; the last ones, with a dozen characters, a liar or a hidden accomplice, will have you thinking like a real detective.

What’s inside

All you need is a pencil. The map, the clues and the satisfaction of pointing out the culprit come with the book.
