Every answer either brings you closer to the truth — or deeper into deception.

A locked room, a stopped watch, and a city where every witness remembers the night differently. Greyhaven, 1897. Clockmaker Elias Voss has been found dead. The watch that could establish his time of death has stopped, the official record does not add up, and nearly everyone has something to hide. Explore the city, examine physical evidence, question the people who knew Voss, and build your own account of what happened. The Greyhaven Files is a story-driven detective adventure about observation and deduction—not combat—and this complete, self-contained case will not simply hand you the truth. INVESTIGATE WITHOUT A GLOWING ANSWER Study illustrated evidence up close and choose the interpretation that makes sense to you. A clue may support more than one explanation, and the most convincing answer is not always the correct one. QUESTION EVERY VERSION OF THE NIGHT Choose what to ask, decide when to press, and watch each witness’s demeanor. Compare their answers with documents, timelines, and details you uncovered elsewhere in the city. BUILD THE CASE YOU BELIEVE Use the case board to review suspects, testimony, evidence, and contradictions. A mistaken deduction does not always lead to a retry screen: it may redirect the investigation, close one line of questioning, or reveal another way to verify the truth.
