William Trevor: Death in Summer [1999] paperback

There were three unexpected deaths that summer. After Letitia died, her husband decided to bring in his mother-in-law to help with the baby. None of the likely nannies had proved suitable. But one candidate was particularly persistent, and her return to the beautiful house in Essex led inevitably to the other deaths ... William Trevor's new novel is a riveting, haunting story of tragedy striking at the heart of apparent ease.
