About The Poisoner’s Handbook
The Poisoner's Handbook is a deduction puzzle game with a macabre theme: you work through problems by testing, observing results and narrowing possibilities.
The interest is in the method rather than the theme — it's structured like a laboratory, where each experiment eliminates options rather than confirming an answer outright.
