A double murder is discovered in Spalding some days after it takes place.
Enquiries by the police and social services reveal that some four years previously Grace was the sole survivor of the horrific massacre of her mother, grandparents and sister at Brocklesby Farm in North Lincol.
The victims are Tina Brackenbury, the foster mother of Grace Winter, a ten-year-old who escapes the killer because she is staying her friend Chloe Hebblewhite\'s house at the time, and Tina\'s infant daughter.
