A passionate birdwatcher and quiet man, he has few relationships and prefers it that way. But when his only friend is found brutally beaten, South's detachment is tested. Not only is he bereft - it seems that there's a connection between the suspect and himself. For South has a secret. He knows the kind of rage that killed his friend. He knows the kind of man who could do it. He knows, because Sergeant William South himself is a murderer.
