Trivia about Pop. 1280
One of Harry Whittington's crime novels, written for Gold Medal in the 50s, never came out in print in his home country. Rejected by Fawcett in the US, it got sold to Whittington's French publisher Gallimard instead (they had been doing a successful set of Serie Noir thrillers, in French-language hardcover editions, and the book fit right in). Can you pick out its unpublished English title?
