During a guided tour of Garre Castle, a man is killed by an arrow after sneaking away from the rest of the group. Shortly thereafter, Mr Howett and his adopted daughter, Valerie, move into Lady's Manor, next door to the castle. Valerie is looking for her mother she has not seen in 20 years. John Wood, a friend of Valerie's brother John Bellamy, who was killed in the war, is also there.
