Bad Dog

Monsters can come in all sorts of disguises.

When a young woman is brutally murdered in the Norfolk countryside, the locals blame Black Shuck - a legendary wild dog. There's only one problem: the wounds weren't made by an animal.
Detective Robert Kett is battling a black dog of his own. With his wife still missing, and the injuries from his last case leaving him in constant pain, everything seems impossible - not least looking after his three young children.
But when a second body appears, even bloodier than the last, Kett finds himself on a hunt for one of the most ruthless serial killers the country has ever seen.
A killer who may be hunting him too.
