New York: William Morrow, 1935. First Edition. Publisher's file copy, with "OFFICE FILE COPY" stamped on the rear panel of the jacket and several penciled annotations and deletions on the front flap and front endpaper. Near Fine in a Very Good or better dust jacket. Evidence of removal on the front pastedown, else book is quite clean. Jacket has no significant loss, only some rubbing at the folds, light fading to the spine panel, and small chips at the corners. A very presentable—and probably unique—copy of the sixth Perry Mason mystery.
