A cooperative mystery adventure developed by vrisch and released in 2023 for Meta Quest 2 and Meta Quest 3, supporting one to four players. Set in the world of Sherlock Holmes, the scenario places players in an urgent investigation: three cabinet members have been found hanged, Holmes himself has gone missing, and midnight is the deadline before the killer strikes again. Players examine crime scenes, gather evidence, and interrogate suspects, then synthesize their findings through a Mind Palace mechanic to build a coherent case. The game draws on immersive theatre conventions alongside VR, framing the experience as an evening-length session designed to be replayable. The whodunit structure encourages careful deduction rather than action, and the multiplayer option allows the investigation to function as a shared social activity. The developer, a small team, describes it as an ongoing project and has invited player feedback to refine the experience.
