London, 1945. Four adolescent orphans and a gravely ill demobilised soldier are squatting in the Belgravia mansion where Maisie once worked as a servant. Their evasive accounts and unexpected combat skills suggest a wartime history that the authorities may not understand, and Maisie attempts to secure their safety before the group is dispersed.
Her inquiry also uncovers information about the experimental aircraft crash that killed her first husband, James Compton. In a country facing rationing, homelessness and psychological exhaustion, Maisie must reconsider long-accepted beliefs about her own past and help another generation damaged by war imagine a future beyond secrecy and survival.
