Ep. 520: Conan deduces a murder victim's revenge via a tainted wine bottle and bloody fingerprint evidence.

520

Kogoro attends a wine appreciation party hosted by collector Murozo Honjo. Conan and Ran observe Honjo arguing with critic Goro Akamaru, after which Conan witnesses Honjo striking Akamaru with a brick. Although Conan cannot find immediate evidence, he discovers blood in a barrel, realizing Akamaru’s body was moved to avoid detection. The only unexplored area is a fingerprint-secured wine storage room. During a tasting, Honjo’s prized wine is ruined because dregs mixed with the liquid. Conan examines the bottle and finds a bloody fingerprint, concluding that Akamaru regained consciousness in the cellar and sabotaged the wine as revenge before dying.
