Detective Inspector Angel must investigate a strange case where both the murderer and the murdered man are without shoes. The victim was a millionaire, adored by beautiful women, particularly the Frazer sisters, who put sparkle into his life and showed him how to spend his money. An antiques dealer and his son are the prime suspects, but they have a rock solid alibi. At the same time, Angel has to investigate a flood and a stink at the Great Northern Bank, which permitted a gang of robbers to escape with millions of pounds.
