From the author: "the Great War is over, and Harry, formerly Captain Henry Bridgeman, is learning how to be a civilian again. Then Sam, who was a corporal in Harry's company, comes back into his life, and he remembers things Harry would prefer to forget."
From pinboard.in: "Harry Bridgeman has been demobilised for almost a year when he meets Sam Jackson, a corporal he had been forced to discharge for sodomy."
