Detective Puzzles: Fiendish Puzzles

Detective logic puzzles: work out who was where and how the theft was pulled off — then name the culprit at the scene. All 60 cases use every trick we have at once: conditional clues, one false clue per puzzle, and groups where only some statements are true. Still solvable by pure logic — just not gently. Deduction only, never guesswork.

Coming soon to Amazon.
