After Cassandra Cass is shot in her bed (by a mysterious hooded figure) while her butler draws her bath, it is revealed that she has been blackmailing subscribers to her society Blue Book. One after another of the suspects (a deposed Balkan King, a banker, a drugged out socialite and the head of a ""psychodrama"" society) more or less confesses to the crime, but each of their descriptions of the event varies slightly from the known facts. Meanwhile, Les keeps insisting that ""the butler did it"". With the help of Cassandra's sexy secretary and a health fanatic, Burke concocts a plan to trap the real killer.

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!

Granny Grabber, the not-so-nice head of a toy firm, is blown sky high by a bomb placed in his giant toy soldier cigar lighter. The killer had to be one of five people who were photographed coming into his office that day (Granny was paranoid about industrial espionage). The victim's sultry secretary, the company's military adviser on all war toys, an aeronautical scientist, a ""James Bond"" wannabe, and the head of a school for juvenile delinquents all come under suspicion. When one of the suspects discovers a vital clue and is murdered, Burke discovers that Granny had plans to make millions by NOT producing a toy!

Burke's vacation south of the border is anything but restful when he is jailed for the murder of a gossip columnist and a popular local fisherman. With the help of his vacation date and the ever-faithful Henry, Burke escapes from prison, but can he outwit the local police chief after all his ID has been stolen? He needs to find out whether the killer is the Nazi, the anthropologist turned voodoo priestess, the novelist, or the sexy sailor gal, before the angry mob catches up with him. When one of the locals is poisoned, Burke knows who the killer is.
