Necroscope

Harry Keogh is the man who can talk to the dead, the man for whom every grave willingly gives up its secrets, the one man who knows how to travel effortlessly through time and space to destroy the vampires that threaten all humanity. In Necroscope, Harry is startled to discover that he is not the only person with unusual mental powers--Britain and the Soviet Union both maintain super-secret, psychically-powered espionage organizations. But Harry is the only person who knows about Thibor Ferenczy, a vampire long buried in the mountains of Romania--still horribly alive, in undeath--and Thibor's insane "offspring," Boris Dragosani, who rips information from the souls of the dead in a terrible, ever-lasting form of torture. Somehow, Harry must convince Britain's E-Branch that only by working together can they locate and destroy Dragosani and his army of demonic warriors--before the half-vampire succeeds in taking over the world!
