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 considers himself a detective, though his actual success rate remains debatable. What he lacks in skill, he compensates for with an unlikely partner: Holmes, a calico cat with an uncanny ability to sniff out the truth in any case. When Yoshitaro's sister Harumi hosts a celebration for her acting troupe, the festive atmosphere quickly turns sinister. A murder rocks the afterparty, and suspicion spreads through the crowd like poison. The usual investigators seem stumped, but Yoshitaro knows exactly who to turn to. What follows is a comedy of errors wrapped around a genuine whodunit, as the bumbling detective and his mysteriously perceptive feline work to untangle the threads connecting cast members, motives, and secrets. Tension and humor collide as red herrings pile up and Holmes' cryptic behavior points toward answers only the cat seems to understand. For viewers who enjoy mysteries with a lighter touch and don't mind their detective work served with a side of chaos and charm, this OVA delivers both laughs and genuine intrigue in one compact package.
