New York: William Morrow, 1939. First Edition. Very Good in a Good plus example of the scarce dust jacket. INSCRIBED by the author on the front endpaper: "To Margie and Babe / with all my love / Daniel Geoffrey Homes Mainwaring." Book is slightly cocked and a bit shaken, otherwise clean with green titles and design quite bright and unfaded; jacket is worn, with chips at the spine ends (neither affecting the publisher's device or lettering), wear at the extremities, and a diagonal crease across the front panel. Basis for the rapid-fire 1941 B-movie, starring Chester Morris and Jean Parker. A difficult book in dust jacket, and an extremely scarce signature.
