A diver discovers five boxes of gold coins in a shipwreck while on a dive for a museum. He goes to ask for a percentage of the find. The next day he turns up dead, an apparant drowning victim. Sandy thinks it was murder, so he enlists Ken to find out what happened and if it is related to a woman the diver reported seeing in the sunken ship the day before his death.

Sandy is hired to find an old acquaintance, the director of a lingere show. He encounters a number of romantic double-crosses. One member of the show entourage turns up dead, an apparent suicide, but Sandy thinks otherwise.
