London, 1931. On the night before the opening of his new and much-anticipated exhibition at a famed Mayfair gallery, Nicholas Bassington-Hope falls to his death. The police declare it an accident, but the dead man's twin sister, Georgina, isn't convinced. When the authorities refuse to conduct further investigations, Georgina takes matters into her own hands, seeking out a fellow graduate from Girton College: Maisie Dobbs, psychologist and investigator.

The case soon takes Maisie to the desolate beaches of Dungeness in Kent, as well as the sinister underbelly of the city's art world. She again uncovers the dark legacy of the Great War in a society struggling to recollect itself in difficult times. But to solve the mystery of the artist's death, she will have to remain steady as the forces behind his death come out of the shadows to silence her.

Jacqueline Winspear delivers another vivid, thrilling, and utterly unique episode in the life of Maisie Dobbs.
