'Safety and security are commodities you can sell in return for excitement, but you can never buy them back.' Yvonne Carmichael is a geneticist, a scientist renowned in her field but one day, she makes the most irrational of decisions. While she is giving evidence to a Select Committee at the Houses of Parliament, she meets a man and has sex with him in the secluded Chapel in the Crypt beneath the Great Hall of Westminster. It's the beginning of a reckless liaison, but there is more to her lover than is at first apparent - as Yvonne discovers when the affair spins out of control and leads inexorably to violence. "Apple Tree Yard" is about a woman who makes one rash choice that ends up putting her on trial at the Old Bailey for the most serious of crimes. Like the highly acclaimed "Whatever You Love", it is part literary investigation of personal morality, part psychological thriller. Both a courtroom drama and an exploration of the values we live by, it is the gripping seventh novel from an author who has been acclaimed as a 'courageous writer, willing to explore deeper territory with each book' ("Independent") and 'terrifically compelling' ("Daily Mail").
