Dame Beatrice Lestrange Bradley is typically consulted for her astute detective skills, but her most recent invitation is anything but typical. She has been summoned to the home of an unknown relative, Romilly Lestrange, who asks not for her assistance in solving a crime, but for her psychiatric opinion of his wife. The young woman, according to Romilly, has developed a troubling habit of tossing items and pets off a cliff top! But Romilly's wife, Rosamund, tells a different story--one of repression and deceit at the hands of her captor. As Dame Beatrice attempts to discern the eccentric from the criminally insane, the news of a family inheritance arises, followed by the discovery of another relative's dead body floating in the sea. Dame Beatrice must use skills both psychoanalytic and sleuthing to uncover the truth...for never has a case been closer to home, and never has her life been in such peril.

Legendary crime fiction author Gladys Mitchell sends her most notorious detective into her most perplexing case: the mystery of the Lestrange family itself.
