A Cross-Out Mystery · 3,000 Suspects, One Culprit

This is a Mystery you actually solve yourself: one blackmailer hidden among 3,000 suspects. Hours of screen-free, single-player detective work in one handsome volume. Track suspects, test alibis, and corner the culprit at your own pace.

A glittering country-house gathering has turned dangerous. Private secrets have fallen into the wrong hands, and someone among a sprawling list of guests, servants, visitors, and associates is responsible. Your job is to uncover the truth before another secret is exposed.

Find the Blackmailer by Lillian Jacobs is a deduction mystery designed for readers who love whodunits, logic puzzles, detective games, and the satisfaction of narrowing an impossible list of suspects down to one.

The rules sound simple: every suspect makes a statement. Every innocent person tells the truth. The blackmailer always lies. Follow the statements, test the possibilities, eliminate the innocent, and determine which single suspect’s story cannot be true.

But with 3,000 possible suspects, spotting that one critical lie is anything but easy.
