Thea Osborne agrees to do a second spell of house-sitting for Lucy Sinclair, in her new home in Northleach. Lucy is scheduled for an operation on her back in Oxford and needs Thea to look after things for a few days. Thea is glad of the change of scene and soon meets several of the townsfolk, and it appears that few of them have any liking for Lucy. When a man is found dead in a Northleach house and turns out to be Lucy's stepson, Thea is once again at the very heart of a police investigation.
