The Killer Isn't Alice

One murder. 42,800 suspects. Nineteen clues. And not a single answer is handed to you before you earn it.
When a high-profile victim is found dead under suspicious circumstances, Alice appears to be the obvious suspect. The evidence points toward her. The timeline seems to fit. The case looks almost solved.
But Alice is innocent.
Your task is to uncover the one person who is not.
The Killer Isnt Alice is a premium fair-play murder mystery logic puzzle built for readers who want a genuine challenge without the frustrations that ruin the experience. No solution is printed beside the suspect registry. No bold answer appears on the next page. No tedious hundreds of pages of repetitive names stand between you and the fun.
Instead, 19 carefully constructed clues progressively eliminate the field from 42,800 suspects to exactly one logically provable killer.
Track evidence. Test alibis. Cross-reference details. Use optional checkpoints to confirm your progress without revealing names. Build your case on dedicated detective worksheets, make your formal accusation, and only then choose whether to enter the protected solution.
Two spoiler barriers separate you from the final reveal, so the mystery remains yours to solve until the moment you decide you are ready.
And when the truth is finally revealed, you will not simply be told who did it. You will see exactly how every clue fits, why Alice was wrongly suspected, and why every other suspect fails.
No guessing. No accidental spoilers. No arbitrary ending.
Just one murder, one airtight deduction, and one true killer.
Can you prove who it is before the final reveal?
