London, spring 1930. Wealthy businessman Joseph Waite hires Maisie to find his missing daughter Charlotte, whose privileged life has also been a form of confinement. The apparently private disappearance becomes more serious when women from Charlotte’s wartime circle are murdered and Scotland Yard begins to see a pattern.
Maisie and Billy Beale trace the victims through friendships formed during the First World War and through secrets protected for more than a decade. The investigation exposes the unequal freedoms available to women in interwar Britain and shows how grief, guilt and family control can turn a shared past into a motive for further violence.
