Information for Where is Mrs Christie? at Theatre at the Tabard, Outer London (Play). Agatha Christie was one of the greatest thriller writers of all time and certainly the most prolific. In 1926, she was at the centre of a mystery as perplexing as any of her fiction, which sparked one of the biggest and most extensive police hunts in history. Her crashed car was discovered in Surrey and the famous author was missing, presumed dead by many, for eleven days. However, she was eventually found at a hotel in Harrogate. She claimed then, and for the rest of the life, that she was suffering from amnesia and remembered nothing. Neither the press nor the police believed her. Did Agatha Christie lie, and if so why? Did she suffer from amnesia? Was it a publicity stunt? Or was there a darker secret involved in this disappearance which was to affect her for the rest of her life? The answer to all these questions will, as in all good thrillers, be revealed!
