If we can trust online translations (which we probably can’t), this 1963 Dutch edition of Erle Stanley Gardner’s 1961 Perry Mason novel The Case Of The Singing Skirt reads “The Girl’s Secret In Leotard”. Well, that’s what I got, anyway. Which might make sense since the model in Dutch photographer Philip Mechanicus’ cover photo doesn’t appear to be wearing a skirt at all. To be fair, many U.S. paperback editions of Gardner’s Perry Mason novels showcased peculiarly steamy covers for their wildly successful mysery/courtroom potboilers. This one? A low-rent California gambling den’s cigarette girl and aspiring songstress who witnesses a gambling debt payoff winds up pinned with a murder rap…Perry Mason to the rescue.
