London, 1945: Four adolescent orphans with a dark wartime history are squatting in a vacant Belgravia mansion --- the owners having fled London under heavy Luftwaffe bombing. Psychologist and investigator Maisie Dobbs visits the mansion on behalf of the owners and discovers that a demobilized soldier, gravely ill and reeling from his experiences overseas, has taken shelter with the group. Maisie’s quest to bring comfort to the youngsters and the ailing soldier brings to light a decades-old mystery concerning Maisie’s first husband, James Compton, who was killed while piloting an experimental fighter aircraft. As Maisie unravels the threads of her dead husband’s life, she is forced to examine her own painful past and question beliefs she has always accepted as true.
