I have no idea. I first actually noticed it in the facsimile hardcover, which I was reading very carefully for the first time, though of course it was rereading of the actual book; and just assumed that it had been corrected in paperback editions later on. Then I became curious and checked. Nope, it's there all the time. I haven't made any kind of study of Sayers's manuscript history; I don't know if anybody else has either. I was so put off by the first biography and critical study of her that I read that I've pretty much been avoiding such things since.
