70 FLIGHTS. 9,000 PASSENGERS. 19 CLUES. 1 KILLER.
A murder has been committed at an international airport, and the killer is hiding among the passengers. Everyone is watching Flight 417 but the killer isn't on it. One guilty name is buried in the flight records, and only logic will find it.

This isn't a murder mystery novel you read passively. It's a murder mystery puzzle book for adults : an immersive logic puzzle and elimination game you solve with nothing but a pencil and your own deduction.

HOW THE CASE WORKS

Read the 21 clues : Each clue is a hard, absolute fact about the killer. Some clear hundreds of innocent passengers at once; others make you look closer at a name, a seat, a passport, a piece of luggage.

Work the flight records : You hold the complete flight records: every flight, every passenger, their seat, class, baggage and passport and who sat in front of and behind them. Cross off every traveler a clue rules out, flight by flight, like a detective working a suspect list.

Find the one name that survives : Only one passenger fits all 21 clues. When that name is the last one standing, you've found the killer.
