Inspector Jim Carruthers

In a small Scottish university town, what links a spate of murders, a targeted bomb explosion and a lecturer's disappearance? Who is pulling the strings? Having returned to Castletown intending to win back his estranged wife, DCI Jim Carruthers finds himself entrenched in the investigation. DS Andrea Fetcher assists him in the hunt for the perpetrators. They need to work fast. But can they truly rely on Jim's old adversary?

A man is discovered stabbed to death in a nature reserve, a ball of cloth rammed in his throat. When a second body is found, Carruthers is convinced that the reason for the deaths lies in the past. But how is the historical disappearance of a boy, the murder of a former journalist and a bitter dispute about a nature reserve connected? Are they hunting for one killer...or more?
