James Kennaway: the cuckold who came from the cold

The NY Daily News reminds us of some literary cuckoldry involving two writers: One famous, one now forgotten.
 The famous one is John le Carré, the preeminent spy novelist of our time, author of, among many other outstanding works of fiction, “The Spy who Came in from the Cold” and “The Little Drummer Girl.”
 The forgotten one is James Kennaway, the Scottish author who was one of the bright stars of the postwar Brit Lit firmament. He first came to prominence in 1956 with the publication of “Tunes of Glory,” a novel about the peacetime clash between two career soldiers at a Scottish Highland regimental barracks.
 In the mid-1960s, le Carré, whose literary career was just taking off, had an affair with Kennaway’s wife, Susan. Kennaway was something of a mentor to le Carré (whose fourth novel, “The Looking Glass War,” is dedicated to him), so the betrayal must have been particularly stinging. The article then continues with an overview of how the affair featured in novels by both men. Susan's swinging nature earns James a solid 7 on the cuckold scale.
