Peter is dead. Somewhere in a list of 22,500 suspects is the one person who did it - and the only tool that will lead you to them is your own logic.This is not a story to be read. It is a case to be solved.You are given 22,500 suspects and 20 clues. Every clue is a true, verifiable fact about the killer. Work through them one at a time, eliminate every name that does not fit, and when a single name remains, you have found the guilty party.There are no narrative tricks and no false trails. The suspect list is deliberately shuffled, so every name must be read and judged on its own - there are no shortcuts and no way to guess your way to the end. Each puzzle resolves to exactly one verified solution.An absorbing, screen-free challenge for puzzle enthusiasts, mystery readers, and anyone who enjoys pure deductive reasoning. Ideal for quiet evenings, travel, and gifting. All you need is a pen and a sharp eye.The answer is sealed at the back of the book.
