The Corpse in the Snowman (Nigel Strangeways, #7)

Nigel and Georgia are asked to come in midwinter to Easterham Manor under the pretense of investigating a psychic incident. Shortly after their arrival, the rather notorious, strikingly beautiful, Elizabeth Restorick is found dead by hanging.

Nigel uncovers evidence of murder, and he soon finds himself once again working with his friend, Inspector Blount of Scotland Yard.
