An Extremely Hard 15,000-Suspect Cross-Out Mystery Puzzle for Adults

Behind the velvet doors of an exclusive 1920s-inspired speakeasy, Captain Palmer’s closely guarded information has been betrayed. Somewhere inside a register of 15,000 suspects hides the culprit—and an accomplice who helped carry out the scheme.

In this extremely hard detective puzzle for adults, you’ll examine the suspect register, follow a trail of logical clues, and systematically cross out everyone who cannot be responsible. Names, table numbers, passwords, drinks, membership records, and coded letter patterns all matter. One careless elimination could send your entire investigation sideways.

The mystery unfolds across three acts, with new evidence introduced as the suspect list narrows. Progress checkpoints help you verify your deductions without revealing the answer.

Perfect for experienced puzzle solvers, armchair detectives, and fans of difficult whodunit games, logic elimination puzzles, escape-room challenges, and immersive crime mysteries.
