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.
