London: Michael Joseph, (1965). First edition. His third mystery. SIGNED by Francis on the title page. Faintest ring marks on front cover, page edges darkened with subtle mottling (not immediately noticeable and not extending to margins), otherwise would be near fine; in good or better dust jacket, which presents better than it sounds -- rubbed, flattened creasing at base of spine and narrow line at middle, few small chips and tears, and extensive staining to the verso, which fortunately is only outwardly visible on the rear panel.
