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!
