The New York Times bestselling author of the brilliantly inventive The Word Is Murder and The Sentence Is Death returns with his third literary whodunit featuring intrepid detectives Hawthorne and Horowitz. When Ex-Detective Inspector Daniel Hawthorne and his sidekick, author Anthony Horowitz, are invited to an exclusive literary festival on Alderney, an idyllic island off the south coast of England, they don't expect to find themselves in the middle of murder investigation--or to be trapped with a cold-blooded killer in a remote place with a murky, haunted past.
