When Matthew Glynn is murdered, Wycliffe is mystified. Why would anyone want to kill him? But a look at Glynn's background reveals tension within the family. Alfred Glynn, an eccentric recluse, has born a grudge against his brother for years. The other brother, Maurice, argued bitterly with Matthew over the sale of family land. His sister Sara is caught out in several crucial lies to the police. Add to this a discontented son, the discovery of valuable documents in the bookseller's safe, and the mysterious, still unexplained disappearance of Matthew's wife years earlier, and Wycliffe faces one of his most impenetrable cases yet. And then another Glynn dies . . .
