Harm None - Will North - Bog

Penwith, the southwest tip of Cornwall, is a land of mystery and magic, of prehistoric monuments, witchcraft...and murder. When an American archaeological team stumbles upon the skeletal remains of a missing child beneath a Stone Age burial quoit, irascible CID Detective Sergeant Morgan Davies and her Scene of Crimes partner, Calum West, unearth a growing list of suspects.
Within days, another body is discovered. Is the killer the mind-reading village witch-who has long been a suspect in the child's disappearance? Is it the drug-dealing partner of the child's heroin-addicted mother? Or is it someone even closer to the investigation? Just as Davies and West close in on their prime suspect, another child disappears.
