Murray Shaw has bought his dream home - the imposing St Margaret's House in the exclusive Edinburgh district of Corstorphine. However, for his wife Rowan his dream is about to become her nightmare. Because St Margaret's House has a dark past. And, unknown to Rowan, that's exactly why Murray bought it. Forty years earlier Murray's school friend Angus lived in the house - until his shocking death in an unexplained arson attack. So what has drawn Murray back to the scene of such terrible memories? Why has his behavior become so furtive of late? And why is the Reverend Shelagh Kerr, minister of the nearby St Margaret's Church, so terrified to learn that Murray has returned?
