New York, David McKay, 1972. First US edition. Originally published 1940, at the beginning of WWII. British Intelligence operatives Murdoch and Dell pose as a honeymoon couple visiting a quaint country hotel. They stumble on spies and thieves, and try to support a plan to align the neutral nations against Hitler. Spine cocked, corners very slightly bumped. A touch of wear to DJ. Small stains to author's note and first page of text. $7.50.
