18,731 Suspects. 18 Evidence Files. Large Print. Pure Deduction - Zero Guessing.
TWO FULL CASES IN ONE: Includes an exclusive QR code unlocking a 2nd complete investigation using the same 18,731-suspect register with 18 brand-new clues!
THE FALCON IS BACK. 18,731 SUSPECTS. ONE OF THEM HAS THE FALCON - AND YOU'RE GOING TO FIND OUT WHO.
Seven years ago, a black bird worth killing for disappeared into an evidence locker and stayed there. Sam Spade thought that was the end of it.
Then it turned up again - dockside, in a crate marked machine parts - and two days after customs logged it into evidence, it walked out the door a second time.
Somebody on the inside took it. A customs man, a warehouse clerk, a longshoreman with the wrong friends. Eleanor Voss wants it back before it disappears for good, and she's brought Spade a list: every name with a plausible reason to have been near that crate in the three weeks before it vanished.
Eighteen thousand, seven hundred and thirty-one of them.
This is a logic-elimination puzzle book, not a novel. Your suspect list gives you names - nothing else. Every clue tests how a name is spelled: how many letters it has, how many vowels, which specific letters it does or doesn't contain, what letter sits in a certain position. No hidden information, no attributes to guess at - everything you need to solve it is checkable directly against the printed list in your own hands.
- 18,731 real suspects - printed in full, waiting to be crossed off one by one
- 18 evidence files - every single one genuinely narrows the list; nothing is filler
- Clues test spelling, not backstory - length, vowels, letters present or absent, letter position
- Clues don't lie - nothing misleads, nothing contradicts
- One guaranteed answer - apply the evidence correctly and exactly one name survives all eighteen
- Pure deductive reasoning - no guessing, no luck, no shortcuts
You're not reading this case. You're working it.
Open the register. Pick up your pencil. The bird is waiting for whoever finds it first.
