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

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.

Inside the paperback, you’ll investigate a complete mystery case featuring:

• 3,000 suspects to work through, 6x9 in book
• A country-house blackmail mystery filled with secrets and suspicion
• An incident report and extortion report that set the case in motion
• Detective-style case photographs and persons of interest
• Thousands of interconnected suspect statements
• A simple truth-versus-lie deduction system
• A worked example to help you understand how to investigate the case
• The final solution included when you’re ready to discover whether your deduction was correct

The investigation begins with Dame Tennant discovering that private secrets have fallen into cunning hands after the corridors of the country house have emptied. From there, the case becomes a massive process of elimination.

This isn’t a book you simply read from beginning to end. Keep it beside you, make notes, circle names, follow connections, question every statement, and build your case like a detective.

Murder mystery puzzles • Logic deduction games • Whodunits • Detective puzzles • Brain teasers • Mystery gifts • Crime-solving games • Challenging paper-and-pencil puzzles
