A hapless detective and a cat with actual supernatural intuition solve a murder at an acting troupe's wrap party. The cat does the real detective work. Yoshitaro stumbles through, gets nowhere, and Holmes sits on the solution until the moment it matters most. This 1992 OVA treats a murder mystery like a family comedy where the family pet is smarter than everyone else in the room, and that gap between human effort and feline certainty is the entire joke.

Yoshitaro Katayama is a hapless detective who shares his home with his sister Harumi and their calico cat, Holmes, whose sixth sense for solving mysteries tends to outshine his owner's. When Harumi's acting troupe gathers for a party after a performance, the celebration turns into a scene of murder and tragedy. Fortunately, Yoshitaro has brought Holmes along. Adapted from Jirou Akagawa's popular novels, this stand-alone OVA blends comedy, drama and a mystery to be solved.
