An intriguing case for Detective Inspector Napoleon Bonaparte begins on a calm October day in an Australian seaside town. Three men set out to sea for a day’s fishing… and do not return. Despite intensive searches, no trace of the men or their boat is found until, weeks later, a passing trawler hauls in a gruesome catch - the head of one of the missing fishermen. It is quite clear that its owner was murdered with a pistol bullet. But by whom, and why, is for Bony to find out.
