A murder mystery logic puzzle book built around a single deduction: 28,000 named suspects, 18 clues that are all true, and exactly one solution. There is no narrative to read through; you cross names off a long shuffled list until one remains, then check the answer at the back. It suits solvers who want a long, pen-and-paper elimination grind rather than a quick crossword or a story-driven whodunit. Compared with typical puzzle books, the scale of the suspect list is the draw and the main barrier: it rewards patience and careful cross-referencing, not speed.
