Frequently Asked Questions

Q1: Are these puzzle books based on real murder cases, or fictional ones?

It varies by book. Gareth Moore's titles use invented, unnamed cases with true-crime framing rather than real victims or killers. CRIMESEARCH and Murdsearch are also built around fictional cold cases. Jack Rosewood's book leans more heavily on real, named cases and trivia.

Q2: What's the difference between a true crime word search and a “solve the case” puzzle book?

A standard word search just has you circling hidden words. “Solve the case” formats like CRIMESEARCH and Murdsearch add a second layer: after finding the words, you use the leftover letters, a missing word, or a decoder code to figure out who committed the crime.

Q3: What's a good true crime puzzle book for someone who isn't really a “puzzle person”?

Start with a word search–based title like CRIMESEARCH, Murdsearch, or Brain Games – Criminal Mind Puzzles rather than a logic-heavy option like The Crime Scene Puzzle Book.
