October 1941. London reels under nightly bombings, and a boy messenger named Freddie Hackett witnesses a murder in the rubble of a bombed-out street. When he later comes face to face with the killer, no one believes him—except Maisie Dobbs.
Maisie, already walking a dangerous line as she recruits for Britain’s Special Operations Executive, knows Freddie is telling the truth. But her work assessing agents for resistance missions in France collides with the investigation, pulling her into a shadow war of betrayal and secrecy.
As enemies close in, Maisie uncovers ties that reach back to the Great War and forward into the heart of Britain’s survival. Stopping the killer is no longer just justice—it may decide the fate of the war itself.
