Bletchley Park, 1943. Cryptanalyst Tom Jericho is recalled after German naval communications abruptly become unreadable, threatening the Atlantic convoys on which Britain depends. Already strained by exhaustion, he must help recover access to the Enigma traffic before U-boats exploit the intelligence blackout.
Jericho’s technical work becomes entangled with the disappearance of Claire Romilly and indications that someone inside Bletchley is concealing evidence. Codebreaking, espionage and personal obsession converge as the investigators race against both the convoy timetable and the security service.
