Phillips Oppenheim, “What Sir Stephen Forgot” in Sinners Beware, Boston: Little, Brown & Co., 1932, p. 158, (first published as “In the Strongroom” in Collier’s Weekly, 11 April, 1931), “If it isn’t Peter Hames?” he cried. “God bless my soul! They told us over in New York that you were living in these parts, but to tumble on you like this! Why, we only landed here two minutes ago. I call this fine.”
