[320pp, top edge blue]: xvi, 304; gilt black cloth, jacket (unpriced & unclipped); 206 x 148 x 35 mm. Second edition of the author's paradigmatic espionage 'novel' (previously 1928), the first to bear his seven-page Preface [Stott A37b note]. Reissued as a primer to war. A virtually new copy in bright jacket with the very lightest edge-wear. Remarkable thus, especially for a wartime book.
