When Elizabeth Nightingale is murdered, DCI Wexford has to sort his way through quite a number of suspects - from the gardener to the household staff, to a permanent Dutch house guest, to the husband Quentin and the victim's brother and his wife. While trying to figure out what really happened on that fateful night that cost Elizabeth's life, Reg Wexford uncovers that the Nightingales' marriage was not as happy as it seemed and that there are secrets to be revealed.
