In an ancient monastery, far from the bustling streets of London, an order of monks celebrates the glories of art and music. Separate from the world, they conceal a secret. For within the sheltered walls, a beautiful woman makes a horrifying promise - and a boy receives a life-saving gift. Soon a monster is preying upon the people of Victorian London. A fiend who thrives on darkness and blood. Victim after victim falls to the beast. No one is safe. The murders are indiscriminate, ruthless. Only the same violent death links them - the torn throat and the bloodless corpse left behind. Lead by the famous vampire hunter Dr. Abraham Van Helsing, six men set out to track down and unmask the killer - and bring the nightmare gripping the city to a blessed end. If they can stay alive. . . .
