This new edition of the world's longest-running play will contain a new introduction, the official play script and exclusive material from the show's archives. As news spreads of a murder in London, a group of seven strangers find themselves in a remote countrysideguesthouse. When a police sergeant arrives, the guests discover - to their horror - that a killer is in their midst.
