““Ok so it’s a murder mystery but you already know who did it. You’re looking for who’s HIDING him, which is somehow worse? You read a line of his letter and cross names off till one is left. Took me a few nights over a week and I kept thinking about page 116 at work lol””
Renée T. ★★★★★
““Bought it because I was sick of scrolling my phone every night and honestly it worked. You just sit there with a highlighter crossing off names and it’s weirdly calming. My daughter stole it off me so now I have to order another one””
Macy L. ★★★★★
““Warning! Addictive. I sat down ‘for five minutes’ and lost two hours. It’s hard but not annoying-hard, and every clue actually matters, which I didn’t expect. Wasn’t happy til I had one name left. Highly recommend 🤭””

About the Author
Clara Whitlock 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 killer is already known, and the reader does every piece of the solving. Who's Hiding the Killer? challenges you to work through the clues, eliminate names by the thousands, and narrow 46,000 names down to one. Every clue is designed to reward careful reading, careful logic, and the patience to see it through.
““I bought this on a whim and finished it in four nights. The clues are hidden in a way that rewards careful readers. Twice I was certain I had the person, only to find one line of the letter I’d skimmed. The ending was earned rather than sprung on you, which made that last name so satisfying.””
Jennifer S. ★★★★★
““I do a lot of puzzle books and this is genuinely unlike any I’ve ever seen. It’s not over in a couple of minutes like a sudoku, it actually makes you think and concentrate. A few clues in you start second-guessing everything and going back over names you already crossed off. In a good way lol””
David R. ★★★★★
““I’ve read dozens of murder mysteries and most of them just tell you a story and reveal the answer at the end. This book was different. It made me pay attention, question my assumptions, and connect clues for myself. Knowing the killer from page one and hunting the person protecting him was a clever twist. I wanted to talk about it with someone the second I finished.””

“This is my new quiet time thing. Cup of tea, highlighter, cross off some names. It’s oddly peaceful, almost zen? But then a clue lands and suddenly you’re a detective and it’s 11pm. A really nice way to spend an evening that isn’t a screen”

“Bought this to work on over coffee and it was the best decision. I thought I’d found the hider by clue six and couldn’t have been more wrong 😂 First mystery book that’s actually made me stop, think, and piece everything together myself. Already looking forward to tomorrow’s coffee.”

★★★★★
“Bought two so my friend and I could do it at the same time and it was the best decision. We compared notes all week like actual detectives. Perfect if you love a whodunnit but want to DO it instead of just reading it”

★★★★★
“This wasn’t even on my reading list. I saw it in an ad and thought it looked interesting. Best impulse buy I’ve made in ages. Completely different from a normal mystery and the letter idea is genius.”

Every clue matters, and every name you cross off is progress you made, which is what makes the solve so rewarding.
✓CAN I ACTUALLY SOLVE THE MYSTERY BEFORE THE END?
Yes. Every clue you need is printed right there in the book, and together they give you everything required to find the person hiding him. There are no impossible twists and no hidden information. Just logic, deduction, and the patience to apply each clue correctly. Do that, and exactly one name survives.
