London, Hodder & Stoughton, 1933. First edition. What would you do if you opened a package to find a man’s head? What would you do if the headless corpse had been swapped for a case of bullion? What would you do if you knew a brutal murderer was out there, somewhere, and waiting for you? Dr. Thorndyke intervenes. Spine slightly cocked and faded. Light wear to extremities, small bookseller's sticker to rear endpaper. $75.00.
