Sometime in September 1935 Sayers finished Gaudy Night and sent it to her publisher, Gollancz. Victor Gollancz wired Sayers on 26 September to say that he very much liked the book. It was immediately copyedited, typeset, and printed, and hit the bookstores on 4 November. To any writer today that sounds impossible: Surely it was published in November 1936?? Nope: it went from submission to publication in little over a month.
