Atkinson quickly establishes place, diction, and a credible spirit of wartime and postwar milieus—while rarely getting bogged down in unnecessary exposition. The tone in the early chapters is both keenly literary and vividly cinematic. Confusion arises, however, with a plethora of secondary characters, i.e., the German sympathizers and double agents, some of whom are being “run” by Godfrey Tobey, some by Perry (her boss). The reader might be forgiven for wondering why many of these clandestine members of the Fifth Column talk so openly about “working for Berlin” or “spying for the Gestapo” in the midst of wartime England.
