The five greatest detectives in the world become murder suspects when Police Chief Gaynor is murdered in a locked room right under the noses of his bodyguards - Tim and Les. As if that isn't bad enough, a huge diamond, belonging to one of the detectives, is stolen at the same time. Rather than solving the case, each of the detectives (the sexy Russian commissar, the head of the Surete, the chief of Scotland Yard, the Tokyo police official, and the arrogant amateur) seems to do everything possible to make Burke's job even more difficult. Even after recovering the missing gem, he is no closer to the solution. Inviting all the suspects to his home, Burke plans to unmask the killer, but first finds Henry's body slumped over the desk, a crimson stain spreading across his shirtfront! (thetvdb.com)
