How It Works
HOW THE CASE UNFOLDS
No detective in this story. You're it.
Step 01. The Arrest
Read the crime
June is behind bars and the official story doesn't add up. Start with the case, meet the ledger, and pick up your first lead.
Step 02. The Ledger
Eliminate 43,000 names
Each of the 17 clues is a puzzle in its own right. Solve it, apply it, and cross off suspects by the thousands, from thousands to hundreds to a handful.
Step 03. The Verdict
Name the killer
When one name survives every clue, deliver your verdict at the online verification site and find out if you're right. No printed answer to spoil it.

ABOUT THE AUTHOR
A mystery with no detective at all.
Charlotte Brooke has always been drawn to puzzles that reward patience: the crossword you can't leave unfinished, the logic grid that finally clicks, the mystery you solve one step ahead of the detective. After years of loving classic whodunits, she wanted to create something different. A mystery where the reader does every piece of the solving.
Every one of the 43,000 names and 17 clues in The Killer Isn't June was placed deliberately, so that careful reading, careful logic, and the patience to see it through are rewarded with the only name that survives them all.
COMPLETE THE INVESTIGATION
Serious detectives bring the right tools.
INTERROGATION ROOM
Still got questions? We've got answers.
A traditional mystery has you follow the story. The Killer Isn't June puts you in the detective's seat: you work through 17 clues, eliminate suspects from a field of 43,000 names, and narrow the case down yourself, one deduction at a time. Every name you cross off is progress you made, which is what makes the solve so rewarding.
Yes. Every clue you need is printed in the book, and together they give you everything required to find the killer. No impossible twists, no hidden information, just logic, deduction, and the patience to apply each clue correctly. Do that, and exactly one name survives.

No. This is a different book entirely. There are a few murder-mystery puzzle books around now, but The Killer Isn't June was designed and built from scratch by Charlotte Brooke. Every one of the 43,000 names and 17 clues was placed deliberately so the puzzle has exactly one provable answer.
No. Plenty of readers solve the case without it. It's there to make the solve smoother: space to work through each clue, track which chapters you've cleared, and log the names still in play. Instead of flicking back through the book trying to remember where you got up to, your whole investigation lives in one place.
Fans of murder mysteries, detective stories, true crime, puzzles and escape rooms. Recommended for ages 13 and up. It's a murder-mystery theme with no graphic violence or adult content, designed for teens and adults who enjoy clues, logic, and elimination.
