When the radio operator on a luxury cruise ship is murdered, Lt. Valcour takes charge. While investigating the crew and the passengers, especially a lovely but lethal man-eater, the killer strikes again - and it's up to Valcour to solve the crimes before anyone else falls victim! Rufus King (1893-1966) was an American author of Whodunit crime novels. He created four series of detective stories: the most famous being Lieutenant Valcour. Modern critics are rediscovering Rufus King's work. Mike Grost, on Golden Age Detective, features a long write up of King, stating: "King had a vivid writing style, with colorful characters, events, and images. He was clearly a born writer."
