5 Reasons Your Evenings Keep Disappearing — And Why

43,000 Suspects Might Be the Fix

From the Case Files of Corex Books

Publisher of Logic-Elimination Mysteries

1. You Don't Remember Last Night. Your Phone Does.

You are sitting down "for a minute." One video becomes forty. A feed becomes a fog. And when you finally look up, it's midnight, your thumb aches, and you couldn't name a single thing you just watched.

Here's the uncomfortable part: it's not a willpower problem. Your phone is engineered by thousands of very smart people to make sure your evening ends exactly this way. You were never going to out-discipline it empty-handed.

The only thing that reliably beats a feed is something more absorbing than the feed — something your hands and your mind can sink into at the same time.

The Killer Isn't June hands you a pen, 17 clues, and a ledger of 43,000 names — one of which belongs to a killer. Crossing off names, clue by clue, is absorbing enough to replace the scroll, and real enough that at the end you can see what your evening built.

Bought it because I was sick of scrolling my phone every night and honestly it worked. It kind of turns the chaos in your brain off? You just sit there with a pen crossing off names and it's weirdly relaxing.

2. Every Mystery You've Ever Read Solved Itself Without You.

Think about the last whodunit you loved. You followed along. You suspected the neighbor. You called it three chapters early — and then sat there while the detective got the credit.

"The detective finds the clues."

"The detective makes the connections."

"The detective corners the suspect."

"The detective names the killer."

"You just watch."

That's the quiet flaw in every mystery novel and true-crime documentary ever made: you're a passenger. And for the reader who pauses the documentary to explain who did it, being a passenger stopped being enough a long time ago.

The Killer Isn't June has no detective in it. You're it. June has been arrested for a murder she didn't commit and her trial starts tomorrow. Every clue is printed in the book, every one solvable by logic alone — and there's no answer inside to peek at. When you think you've found the killer, you submit your verdict online and find out if you were right.

Most mysteries simply tell you a story and reveal the answer at the end. This book was different. It constantly encouraged me to pay attention, question my assumptions, and connect clues for myself.

3. When Life Gets Heavy, Your Mind Needs Somewhere to Go.

Some seasons are just a lot. Recovery. Caregiving. Stress that follows you from room to room. And in those seasons, "just relax" is useless advice — because an unoccupied mind doesn't rest, it circles.

What actually helps isn't emptiness. It's absorption: a task structured enough to hold your full attention, and gentle enough to pick up and put down between everything else life is asking of you.

Psychologists have a word for that state. Our readers have a simpler one: they call it their quiet time.

The Killer Isn't June works in sittings. Solve a clue, clear a few hundred names, set it down, come back tomorrow. It asks nothing of you except attention — and in exchange it gives your mind one clean, solvable problem in a world full of unsolvable ones.

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.

4. Your Brain Doesn't Want Rest. It Wants a Worthy Opponent.

You've felt the difference. A sudoku is over in nine minutes. A word search doesn't fight back. A phone puzzle exists mostly to sell you gems.

They pass time. They don't use you.

The problem isn't that you don't like puzzles. It's that you outgrew the ones on offer.

The Killer Isn't June is built like a single enormous logic problem: 17 interlocking clues, each collapsing the suspect pool — from thousands, to hundreds, to a handful, to one. Exactly one name survives every clue. It is not over by dinner.

5. "Watching Something Together" Isn't Really Together.

Be honest about your last few nights in: two people, one couch, one show neither of you chose with conviction — and two phones out by the second episode.

Sitting side by side isn't the same as doing something together. The evenings people actually remember have a shape to them: a shared problem, a little friendly disagreement, and a moment where somebody gets to say I told you it was her.

That's also why this book keeps getting bought twice — one to keep, one for the friend, the mum, the partner who thinks they'd solve it first.

The Killer Isn't June is collaborative by design: one book comfortably runs a whole table of amateur detectives, arguing over clues and defending their suspects. Or buy two copies and race — separate ledgers, same killer.

First correct verdict wins bragging rights forever.

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.

I've never seen anything like it.

Ok so it's a murder mystery but YOU solve it. You cross them off one by one using the clues until you find the killer. Took me a few sittings over a couple of days and I kept thinking about it when I put it down lol.

Warning! Addictive.

I sat down 'for five minutes' and lost two hours. It's hard but not annoying-hard, and honestly so satisfying when a clue clicks and you get to cross off a whole chunk of names. Wasn't happy til I solved it.

It kind of turns the chaos in your brain off? You just sit there with a pen crossing off names and it's weirdly relaxing. My teen stole it off me so now I have to order another one.

Unlike any puzzle book I own.

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.
