Murder, Made Personal — Instant Personalized Murder Mysteries

First edition

The Last Party at Blackthorn Manor

Eccentric collector Edmund Blackthorn invites your group to his manor for one final gathering. Before midnight, he promises to expose a betrayal committed by someone in the house.

He never gets the chance.

Choose how you want to play. With 1–5 human players, you enter Detective Mode: investigate six scripted offline suspects, question them round by round, and solve the case from the evidence. With 6–8 human players, you enter Party Mode: your real guests become the suspects themselves while the underlying mystery stays fixed, tested and solvable.

Personalized in minutes.

Choose your mode
