In this, the tenth Simon Serrailler crime novel, Simon must engage with his own demons as Lafferton struggles to cope with a series of crimes that threaten the sanctity of hearth and home. On the face of it DC Simon Serrailler has had time to recuperate after the violent incident that cost him his arm, and nearly his life. He is back in harness at Lafferton CID, but is spending his spare time high up in the cathedral roof, making drawings of the medieval angels which are being restored. Lafferton is going through a quiet patch, so far as crime is concerned, until one rainy night two local men open their front door to a couple seeking shelter. A serious error of judgement in the investigation puts Simon's reputation on the line and calls into question how full his recovery has really been. In her new role as a private GP, Simon's sister Cat's medical and counselling skills are tested by terrible and unexpected events at the homes of two very different Lafferton women. Simon and Cat's unreliable father, Richard, has returned to live nearby, in a luxury apartment for the well-heeled over 60s. He's soon up to his usual tricks.
