"How Much Evil Can a Woman Endure?" pants Popular Library. I suspect that some sensation-seeking readers may have been disappointed with what was actually between the covers, however.
Well, witness now Bantam's 1949 paperback edition of Holmes' "most famous case,": The Hound of the Baskervilles. Judging from this cover, the "hound" of the title would seem to be a man.
As I recollect this cover actually has some basis in events from the book, described at second hand. But you have to to flip to the back cover to learn about the actual hound of Baskerville legend. Perhaps a better title to go with this cover would have been The Woman in Red.
