Deadspawn : Necroscope V
By Brian Lumley
Series: Necroscope

"There's a maniacal murderer on the loose, brutally slaughtering young women with a ferocity that rivals that of the vampires Harry Keogh has spent his life combatting. The Necroscope's been asked to solve the crimes... asked by the dead spirits of a madman's victims.

Harry cannot turn down a request from the dead... even if it costs him his soul. In the climatic battle with the vampires, mankind prevailed and purged the vampires from earth - thanks to Harry, his team of psychically gifted spies, and Faether Ferenczy, long dead 'father' of the world's vampires, who betrayed his own kind.

But Harry's alliance with Faether has a terrible cost - Harry's very humanity is under attack from the vampire evil coiled in his mind!" (from book cover)
