About the book

About Who Killed Margaret: The 6,400-Suspect Murder Mystery Logic Puzzle

Margaret is dead. One of 6,400 suspects killed her, and you have 18 clues to work out which one. This is not a story to read. It's a case to solve. Every clue is a precise, verifiable fact about the killer. Apply it, cross out every name that fails it, and move to the next. There are no shortcuts and no way to guess your way to the end. The list is deliberately shuffled, so every name has to be read and judged on its own. Work through all 18 clues and exactly one name will be left standing. That name is the killer. HOW IT WORKS Turn to the suspect list. All 6,400 names, numbered and ready. Turn to the clues. Work through them one at a time with a highlighter, eliminating as you go. When one name survives every clue, you've closed the case. The answer is sealed at the back. PERFECT FOR Puzzle solvers who want something they can't brute-force True crime and mystery fans Screen-free evenings, long flights, quiet Sundays Anyone who thinks they'd make a good detective One name. Eighteen clues. 6,400 suspects. Grab a highlighter.
