In London, 1931, the controversial artist Nick Bassington-Hope falls to his death. The police rule it an accident, but Nick's twin sister, Georgina, a wartime journalist, isn't so sure. When the authorities refuse to consider her theory that Nick was murdered, Georgina seeks out an old classmate from Girton College, Maisie Dobbs, psychologist and investigator, for help. Before long the case leads Maisie to the desolate beaches of Dungeness in Kent, and into the sinister underbelly of the city's art world.
