How 46,600 suspects became the internet's favourite obsession

The Killer Isn't Alice opens on a very bad morning. Alice Starling is missing, and the police find three things in her flat: a dead body, a cryptic note, and a folder of names. Somewhere in that folder — 46,600 of them — is the person who did it. Alice says she's innocent, and she's left you eighteen clues and the job of proving it.

What you're actually doing

There is no plot to follow and no solution printed at the back. You work the clues one at a time and cross out the names that can't possibly be the killer. Some clues are almost mean in their simplicity — the killer's name is longer than three letters, it doesn't start with an S, it contains at least two vowels. Others make you hunt: the killer appears on a page with a repeated name, or in a chapter that also contains all four Beatles. Slowly the sea of names drains away until one is left standing.

How it blew up

The book was self-published in February 2026 by Iris Starling — the pen name of Liz Blackwell, who made it with her husband and collaborator Kevin Fray. The response was far bigger than anyone had expected, and publishers around the world stepped in to print and distribute it properly. The version on the shelves now is the Updated Edition: same eighteen clues, but every name has been changed, so even people who already solved it are starting again, with a bonus puzzle thrown in.

Can you check your answer?

Yes, but not in the book. Once you have a suspect in mind, you submit a tip to the Chipping Mere Constabulary through the book's own website, and they tell you whether you've got the right person. That single detail is a large part of why it's so addictive — you can chase the answer for hours without ever being handed it.

Is it worth the fuss?

If you like methodical, quiet work and you don't mind a pencil in hand, absolutely. If you want a story with people in it, this isn't that — pick up In Cold Blood or I'll Be Gone in the Dark instead. The UK paperback is £14.99, and it's the cheapest evening of detective work you'll find.
