"Legendary stage and movie star Sir Nigel Bellingham arrives on Cape Cod to star in a stage production of The Hound of the Baskervilles put on by the West London Theater Festival. When Sir Nigel, some of the cast, and the director visit the Sherlock Holmes Bookshop at 222 Baker Street, owner Gemma Doyle realizes that Sir Nigel is not at all suited to the role. He is long past his prime and an old drunk to boot. The cast, in particular the much younger actor who previously had the role, are not happy, but the show must go on. Before the play opens, Leslie Wilson, mother of Gemma's best friend Jayne, arranges a fundraising afternoon tea to be catered by Mrs. Hudson's Tea Room. The event is a huge success, but when it's time to leave, Sir Nigel has gone missing--only to be found at the bottom of the rocky cliff, dead. Along with the body, Gemma finds evidence incriminating Leslie Wilson. When the police focus their attention on Leslie, despite the numerous other suspects, the game is once again afoot, and it's up to the highly perceptive Gemma and the ever-confused but loyal Jayne to clear Jayne's mother's name"--Dust jacket.
