When savage death stalks the British countryside, there’s only one man to call....

In the aftermath of a vicious attack, Tara Pride, a young American student, doesn’t know where to turn. Terrified and distraught over the death of her friend, she’s convinced this is more than just wild dogs or rabid animals. So she reaches out to the one man who might believe her - paranormal investigator and Cambridge professor, Marcus Mortlake.

At first glance, Mortlake seems an unlikely candidate to battle the supernatural considering his eccentric character. But despite his curmudgeonly exterior, Mortlake has faced evil beyond imagination, and put his life on the line countless times to defend humanity. 

Now, Mortlake and Tara find themselves facing a deadly enemy: Rupert Gonfallon, a wealthy and sadistic Lord who owns the land where the attack took place. And Mortlake is certain Rupert is connected to a string of bloody murders.

But the truth is even more dangerous than the professor suspects. A pack of savage killers lurks within the Lord’s estate harboring a sinister agenda. Infecting themselves with an ancient curse to gain power and strength, these ravenous beasts claim the dark forests as their territory.

Now, their infection is spreading. And unless Mortlake can stop them, the countryside will run red with the blood of fresh prey....
