Meitantei Conan

Synopsis

Kogoro is invited as a guest to a wine appreciation party hosted by a wine collector named Murozo Honjo. While exploring the villa, Conan and Ran notice Honjo in an argument with a wine critic named Goro Akamaru. From afar, Conan witnesses Honjo smashing a brick into Akamaru's skull.

Conan runs to their location but is unable to find evidence of the assault. While Conan investigates, he notices blood in a barrel and realizes Akamaru's body was stored there but moved to a different location so he would not be found. Conan realizes the only room he had not investigated is the wine storage room which is secured by a system requiring Honjo's fingerprint. During a wine tasting ceremony, Honjo's prized wine has been found to have been shaken and subsequently caused the dregs to mix with the wine and ruining the taste. Conan examines the bottle and finds a bloody fingerprint; This leads him to conclude that Akamaru regained consciousness while imprisoned in the wine cellar and ruined Honjo's wine in an act of revenge.
