"Agatha Christie hardcover collection"--T.p. verso.

At the request of archaeologist Dr. Eric Leidner, Amy Leatheran has accepted a position as companion to his wife, Louise, a woman prone to nervous terrors. What is the young nurse to make of Mrs. Leidner's bizarre stories of her first husband, a dead German spy, who has returned in a rage to destroy her new marriage? Stories of threats and dreadful warnings? Yet it's more than a flight of fancy that bludgeons poor Mrs. Leidner to death. - Publisher.
