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 writeup of King, stating: «King had a vivid writing style, with colorful characters, events, and images. He was clearly a born writer.»
