"I don't say this lightly — this is the most original book I've picked up in years. It's not a novel, it's not a standard puzzle book, it's something completely new. You're handed 46,600 names and 18 clues and told to find a killer. That's it. No story to follow, no author holding your hand. I stayed up until 2am three nights in a row working through it. The moment I narrowed the list down to under a hundred names I felt my heart rate actually go up. Submitted my answer on day four and got it right on the first try. I haven't felt that satisfied finishing something in a very long time. If you love logic, deduction, and mysteries — this is the one. Nothing else comes close.

"My husband is obsessed with crime podcasts and logic puzzles so I bought this on a whim for his birthday. Within two hours of opening it he had spread papers across the entire dining table and was completely unreachable. Four days later he emerged, looked up from his notes, and said "I got her." He was right. He immediately started asking if there were more. I've since bought two more copies — one for his brother and one for our friend who does cryptic crosswords competitively. Both of them had the same reaction. This book does something to people. Absolutely brilliant gift. Verified Purchase · Helpful to 2,187 people"
"I genuinely did not think a book could make me feel like an actual detective. I was wrong. 🔍 The Killer Isn't Alice by Iris Starling is not a novel. It's a case file. Alice is missing, framed for a murder she didn't commit, and she's left you with 18 clues and a list of 46,600 suspects to find the real killer. I worked on it every evening for a week. By day four I had eliminated tens of thousands of names. By day six I had one suspect. I submitted my answer and I was right. The satisfaction of solving it is unlike anything I've felt finishing a book before. Highly recommend if you love puzzles, crime, or just want something that actually makes you think. 📖 #TheKillerIsntAlice #IrisStarling #MurderMystery #PuzzleBook #Onera #BookTok #CrimeFiction"
"This book broke my brain in the best possible way 🧩🔪 No plot. No chapters. No narrator guiding you along. Just you, 18 clues, and 46,600 names standing between a missing woman and justice. I thought I'd crack it in a day. It took me nine. And I loved every single minute of it. What's genius about The Killer Isn't Alice is that there are no red herrings — no tricks the author is playing on you. Every clue is real. Every elimination is satisfying. And when you finally land on one name out of forty-six thousand, you feel it. Perfect for fans of Murdle, logic puzzles, or anyone who wants a proper screen-free challenge. Get yours from Onera. 📦 #MurderMystery #LogicPuzzle #IrisStarling #TheKillerIsntAlice #Onera #ReadersOfInstagram"
"I've been reading mystery fiction for thirty years. I've read cozy mysteries, hardboiled noir, psychological thrillers, locked-room classics. I thought I'd experienced everything the genre had to offer. The Killer Isn't Alice proved me wrong. What Starling has done here is strip the mystery down to its purest form — pure deductive reasoning, applied to a real dataset, with no authorial interference. The 18 clues are precise, fair, and completely satisfying to apply. There are no tricks, no misdirection, and no moments where you feel cheated. I solved it in six sittings. The final narrowing — when the list collapses from hundreds to dozens to single digits — is genuinely thrilling in a way I didn't expect from a book with no narrative whatsoever. Remarkable achievement. Shelved in: Mystery · Puzzle · Favourites · Highly Recommended · Read-In-One-Sitting"
What Our Customers Are saying...
The most satisfying thing I've read this year
I picked this up on a recommendation and had no idea what I was getting into. By page ten I realised this was unlike anything I'd ever read. By day three I was carrying a notebook everywhere, scribbling elimination notes between meetings.
The structure is deceptively simple. 46,600 suspects. 18 clues. Apply each clue, eliminate everyone who doesn't fit, repeat. But the execution is brilliant — the clues are layered in a way that keeps the field narrowing satisfyingly without ever feeling arbitrary.
I got the answer on my first submission. The feeling of typing that name into the website and receiving confirmation was genuinely one of the most satisfying moments I've had as a reader. Iris Starling has created something special here.

Finished The Killer Isn't Alice last night — honest review
Saw this mentioned a few times on here and finally caved. Just finished it last night. Here's my honest take.
First: it's genuinely unlike anything else. If you go in expecting a story you'll be confused. There's no narrative — just a premise, 18 clues, and 46,600 names. That's the whole thing.
Second: it's harder than it looks. The first few clues feel almost too easy. Then you hit clue seven or eight and you realise the remaining list is still in the thousands and you have to really start thinking carefully.
Third: the payoff is real. When I finally landed on my answer and submitted it online and got the confirmation — I actually said something out loud to my empty apartment.
Do it properly. Don't look up hints. Take notes. It's worth it.
TL;DR: Legitimately original, properly challenging, extremely satisfying. 10/10 would solve again.
My book club did not expect this when I suggested it. Neither did I honestly. 😂

We usually read novels — literary fiction, the occasional thriller. This month I suggested The Killer Isn't Alice by Iris Starling because two people in the group love puzzles and I thought it might be a fun change.
We ended up splitting into teams and competing to solve it first. We had three separate spreadsheets going. There were arguments about clue interpretation. Someone brought a whiteboard to week two.
We all got the same answer. We were all right.
I genuinely cannot remember the last time a book caused that much engagement in our group. Iris Starling has done something completely new here and it is absolutely brilliant. Grabbed ours from Onera — fast delivery and came really well packaged.

I finished The Killer Isn't Alice last week and I'm still thinking about it. 46,600 suspects. 18 clues. You are the detective. There is no story — just evidence, logic, and your brain against a list of names.
I was so sure I knew who it was by day three. I was wrong. Took me until day seven to lock it in properly. Got it right on my first submission and genuinely screamed.
If you like Murdle, logic puzzles, true crime, or just want something that actually challenges you — this is it. Get it from Onera. Link in bio. #TheKillerIsntAlice #IrisStarling #PuzzleBook #MurderMystery #BookTok #LogicPuzzle
I bought it as a gift. My friend refused to talk to me until she finished it.
I bought The Killer Isn't Alice for my best friend's birthday because she's obsessed with true crime and logic puzzles and I thought the concept sounded perfect for her.
She called me the day it arrived, already three hours in, to tell me it was the best thing I'd ever given her. She then went quiet for four days.
On day five she texted me: "Got her. First try. I need you to find me another one."
I've since bought three more copies — for her sister, for our friend who does escape rooms competitively, and one for myself because after watching her reaction I couldn't not. This book does something to people. It's genuinely one of a kind.
Highly recommend for anyone buying a gift for a puzzle lover, a mystery fan, or honestly anyone who says they get bored easily. They won't be bored.

What exactly is The Killer Isn't Alice — is it a novel or a puzzle book?
+
It's neither — and both. The Killer Isn't Alice is a completely new kind of experience that sits somewhere between a murder mystery and a logic puzzle. There is no story to follow, no narrator, and no plot. Instead, you're handed a real case: Alice Starling is missing and framed for a murder she didn't commit. She's left you 18 clues and a binder of 46,600 suspect names. Your job is to apply the clues, eliminate the innocent, and identify the one killer hidden in the list. Think of it less like reading a book and more like working an actual case file.
How difficult is it? Do I need any special knowledge to solve it?
+
No special knowledge required — just patience, logic, and attention to detail. The puzzle is challenging but completely fair. Every clue is precise and designed to be applied systematically, with no red herrings or narrative tricks. Most readers solve it within 4–10 days working at their own pace, though some finish faster and some take longer. The satisfaction comes from the process of elimination itself — each clue narrows the field, and the momentum builds the closer you get to one name.
How do I know if my answer is correct?
+
Once you've worked through the clues and landed on a suspect, you submit your answer online through the official solution page. The system will confirm whether you've correctly identified the killer and cleared Alice's name. This interactive element is part of what makes the experience so unique — the puzzle extends beyond the physical book and gives you a real moment of resolution when you crack it.
Is the solution included in the book?
+
No — the solution is not printed anywhere in the book. This is intentional. The Killer Isn't Alice is designed to be solved, not spoiled. The answer is verified through the online submission page, which means there's no risk of accidentally seeing the answer while flipping through pages. Take your time, trust the clues, and submit when you're confident. The answer is in there — Alice made sure of that.
Can I do this with a group or is it a solo experience?
+
Both work brilliantly. Many readers have solved it solo as a personal challenge, working through it over several evenings with a notebook. But it also makes for an extraordinary group activity — book clubs, couples, families, and friend groups have all used it as a collaborative puzzle, splitting into teams or working through clues together. If you're looking for something different for your next book club or game night, this is it.
