In this hardboiled murder mystery set on the secluded Welsh island of Anglesey, DI Tudor Manx leads the hunt for a brutal serial killer.

A woman has been murdered and mutilated in her own home; her liver cut out, and a message left within it.

Tasked with leading the case, DI Tudor Manx identifies several suspects, including the victim’s estranged husband. But all trails run cold.

Then, another victim dies – and from the modus operandi it seems that North Wales police are dealing with a serial killer. But who would target the inhabitants of such a peaceful island?

As the death toll increases, Manx and his colleagues must pick their way through long-forgotten history to trace the killer. But when one of them disappears, it seems that solving this crime may come at a terrible price.
