A series of baffling murders among a group of imprisoned agents threatens the outcome of World War II in this chilling mystery from the New York Times bestselling author of Mr. Churchill´s Secretary. November, 1942. World War II is raging, and former spy Maggie Hope knows too much: what the British government is willing to do to keep its secrets, who is lying, who the double-crossers are. She knows exactly who is sending agents to their deaths. These are the reasons Maggie is isolated on a remote Scottish island, in a prison known as Killoch Castle. When one of her fellow inmates drops dead in the middle of his after-dinner drink--he´s only the first. As victims fall one by one, Maggie will have to call upon all her wits and skills to escape--not just certain death . . . but certain murder. For what´s the most important thing that Maggie Hope knows? She must survive. Praise for The Prisoner in the Castle
