The Lottery Killer
What's inside?
What's inside?
'The Lottery Killer' is one complete murder case, handed to you the way an investigator would receive it. A philanthropist dies of poisoning at his own charity gala. His wife is arrested for it, and what she leaves behind is fifteen clues and a lottery register holding 6,000 ticket records — one of which bought a man's death. Your job is to read the evidence, rule out everyone the evidence clears, and end up holding the single ticket that leads to the killer. Nothing is guessed. Nothing is handed to you.

The first murder mystery with suspect faces
Real investigators don't guess, they narrow. 'The Lottery Killer' hands you that seat: one poisoning, fifteen clues, suspects you can actually look at, and 6,000 ticket records standing between you and the answer.
You'll learn to read evidence for what it says rather than what you hope it says, discard everything that doesn't move you forward, and stay with a problem past the point most people quit — which is the difference between people who notice things and people who don't.
🧠 thinking that stays sharp long after the case closes
Stop guessing, start ruling out on purpose
Clue one feels like a wall. By clue five you've stopped skimming and started eliminating deliberately, and by the last one you're working the register the way an investigator works a case file.
That shift is the whole point of the book. You aren't grinding through 6,000 tickets — you're building a way of thinking that makes complicated problems look a great deal smaller than they did before.

How It Works
-
Each clue reveals one detail about the killer's ticket — the time, the amount, and often what they didn't do.
-
Work the register and cross off every ticket the clue rules out. Each elimination narrows the field.
-
Follow the evidence until one ticket is left. If your reasoning holds, you've found the killer.

Bought this thinking it'd keep me busy for an evening. Three nights later I'm still going, pencil in hand, arguing with myself about whether the guy in the bowler hat is actually clean. My phone's been face-down the whole time, which honestly never happens.

I planned to solve just one clue before bed and ended up doing five. There's something ridiculously satisfying about crossing off rows of suspects and watching the page empty out. My wife started looking over my shoulder and now she's got her own theory.

FAQ
6,000 tickets sounds impossible. Is it actually solvable?
6,000 tickets sounds impossible. Is it actually solvable?
Entirely. Every clue is built to knock out large blocks of the register in one go, so the field collapses much faster than the number suggests. By the midpoint you're working a shortlist rather than a crowd. Every ticket is removed by evidence, never by guessing, which is why finishing feels earned instead of lucky.
Do I need puzzle or detective experience?
Do I need puzzle or detective experience?
None. The method is taught to you inside the book, starting with clues that clear the field quickly before the reasoning gets more demanding. If you can read carefully and think in order, you can finish this.
How long does it take?
How long does it take?
Most solvers spread it across several evenings rather than one sitting, and plenty deliberately stretch it out. There's no timer and no pressure — you can stop and restart whenever, because your progress stays marked on the page.
Is it a story I read, or a puzzle I solve?
Is it a story I read, or a puzzle I solve?
You solve it. No detective steps in at the end of a chapter to explain it for you. The case arrives as clues, records and Clara's notes, and the only route to the killer is working the evidence yourself.
Is the solution included?
Is the solution included?
Yes, in full at the back. It walks the reasoning through step by step, so once you've named your ticket you can trace how each clue narrowed the field and see precisely where the answer was hiding all along.
Is it too hard, or too easy?
Is it too hard, or too easy?
Neither, and that's deliberate. It's demanding enough that finishing means something, but every clue plays fair and nothing hides behind a trick. The red herrings only catch people who guess — working methodically is always rewarded.
Can more than one person do it?
Can more than one person do it?
Yes, and many prefer it. Working it with someone else means arguing over clues and catching what the other missed. It holds up just as well alone, which is why it lands so well as a gift for anyone who likes a mystery.
