Detective Conan

Kogoro is invited to a wine appreciation party by Shiratori. While there, Conan witnesses an argument between two men and sees one attack the other. When he finally arrives at the crime scene, there is no sign of the attacked man. The other man is obviously hiding him, but Conan cannot seem to find proof. After finding a reason to trick people into entering the cellar, they find the victim unconscious and the culprit is arrested.
