Each Man Kills:

A drunken old farmer is murdered and Swansea police detective Harry Lambert is unable to discover a motive for what looks like the work of a professional killer. But before long the hunter becomes the hunted as an ex-SAS soldier escapes to remote, rural west Wales, pursued by DI Lambert. The trail is strewn with all manner of intriguing debris: terrorism; Celtic mysticism; and tortured relationships. Each man struggling to shrug off the complexities of the past. Each man having to surrender the present. Each man, in his own way, killing.
