When Detective Constable Connie Childs is dragged from her bed to the fire-wrecked property on Cross Farm Lane she knows as she steps from the car that this house contains death. Three bodies discovered - a family obliterated - their deaths all seem to point to one conclusion: One mother, one murderer. But D.C. Childs, determined as ever to discover the truth behind the tragedy, realises it is the fourth body - the one they cannot find - that holds the key to the mystery at Cross Farm Lane. What Connie Childs fails to spot is that her determination to unmask the real murderer might cost her more than her health - this time she could lose the thing she cares about most: her career.
