New York: Harper & Brothers, 1930. First edition of the author's first book, a Harper Sealed Mystery. YELLOW SEAL PRESENT but opened resulting in chipping to its fore edge where tipped to p.211 (not affecting any text). Rear half of the seal, which is unprinted and tipped to rear free endpaper, is fine. Blue cloth boards stamped in lighter blue. Cloth at head of spine frayed, otherwise about very good lacking dust jacket.
