Castle Keyvnor on the rocky, remote coast of Cornwall, is an ancient place with a reputation for things that go bump in the night, even in the sophisticated Regency period of England. The Earl of Banfield has died and the new earl and his family are at the castle for the reading of the will, along with ghosts and witches, ghouls and pixies on this most unhallowed of Halloween nights in 1811. Hal Mort, Lord Blackwater, finds himself in Keyvnor, and finds himself aware of ghosts for the first time in his life; and he is more than aware of Lady Morgan, Banfield's daughter. Two ghosts play matchbreaker and matchmaker for Morgan and Hal. Can Morgan and Hal deny the existence of the ghosts? Only if they can deny their growing attraction for each other.
