A disoriented, rambling stranger walks into the detective agency asking for the Master Detective by name — and the case they bring with them is the story of Mrs. Agnes Bishop. What seems at first like confusion or minor distress takes an alarming turn when the visitor mentions a name that should not exist in this timeline. From there, the investigation runs through family secrets, jealousy, questions of identity, and the unsettling sense that someone other than the detective is controlling the case. A new enemy to face. Deadly traps to survive. The Bishop family mansion to explore. A new chapter in the classic Hidden-Object Puzzle Adventure series — one that may reframe everything you thought you knew about the detective's own past.
