Final Curtain (The Alleyn Mysteries)

Troy Alleyn, Inspector Roderick Alleyn's beautiful young wife, is engaged to paint a portrait of Sir Henry Ancred, famed Shakespearean actor and family patriarch, but she senses all is not well in the dreary castle of Ancreton. When old Hnery is found dead after a suspicious dinner and an unfortunate family fracas, Troy enlists the impeccable aid of her husband to determine who among a cast of players would have a motive for murder -- and the theatrical gift to carry it out.
