'A must-read for murder mystery lovers' DAILY MAIL 'Ellis conjures up an immersive, authentic world in this evocative series' FINANCIAL TIMES 'Gripping...expertly combining a crime mystery with a wartime thriller....a potent mix which has produced this excellent novel' ALEX GERLIS ***AN ASPECTS OF CRIME BOOK OF THE YEAR*** WINNER OF THE 2026 COB AND PEN LITERARY AWARD*** London. Spring 1943. While Europe continues to suffer under the iron fist of Nazi occupation, Britain remains battered but unbowed. DCI Frank Merlin, already contending with a booming wartime crime wave in the capital, is confronted with a baffling case: the brutal murder of a respected doctor. Following a puzzling trail that leads him into the hidden corners of clubland - and which appears to be linked to the disappearance of both British and American officers - Merlin must untangle a dark web of shocking secrets.
