London: Hodder & Stoughton, (1941). First edition. Hardcover. Very Good / Very Good. Original light blue boards, lettered in black to the spine. 8vo - 288 pp. The blue cloth has some spotting to both the front and rear panels. There is some foxing to the fore-edge and bottom edge. The book remains solid. The jacket has had some professional restoration. There was some old tape on the exterior near and around the spine which had to be removed. This has been done - and superbly - and most important - out of necessity lest the jacket perish. The jacket is price-clipped as well. A World War II novel of espionage as a team of British Agents infiltrate and engage Fifth Columnists in Holland. Very rare in jacket.
