Heather Barnett's mutilated body was discovered by her son and daughter on their return home from school in Bournemouth one November afternoon. The police quickly ascertained that the murder was premeditated and meticulously planned down to the last macabre detail: the killer had not left one single piece of DNA evidence -- even the bloody footprints from a distinct pair of trainers did not lead out of the house but ended in the front room, without any further trace. As a bizarre and sickening calling card the killer placed a lock of someone else's hair in the victim's hand. Detectives were shocked by the savagery of the murder and baffled by the apparently sadistic ritualism of the killing. Many long months of enquiries led to an eventual lead from Interpol: the parents of a missing girl in Italy had been posted a lock of hair. Could the two murders be linked and had the police just made the breakthrough they so desperately needed? In this in-depth and chilling book acclaimed crime writer Michael Litchfield investigates the full story of the killer behind these terrible murders.
