Necroscope II: Wamphyri
Brian Lumley
 The spirit of Harry Keogh now resides in his son, Harry Jr. When his infant son sleeps, Harry can roam the Continuum and speak to the dead, but is gradually losing his control as the son "reels" his father's spirit back in. Roaming in his spare time, Harry discovers that Thibor had infected a pregnant woman with a small part of his flesh, which results in a lesser breed of vampire, albeit a still formidable one. This youth, Yulian Bodescu, retains many vampire abilities: hypnotism, increased lust, bodily transformation, regeneration, and creating thralls (lesser vampires that are infected with a shed body part of the master vampire). Harry eventually contacts Faethor Ferenczy, a master manipulator (as all vampires are), who was not ready to die but was forced to when he was pinned beneath an unmovable column. When Faethor died, a small worm like (leech) creature left his body, which was also killed. Talking to Faethor, Harry discovers that the creature is the "true" vampire and source of the Wamphyri power, longevity, and when the two beings are merged, they are Wamphyri. Faethor tells Harry about Thibor, who was a mighty warrior centuries prior, and how he infected Thibor with his sole wamphyric egg. Thibor was to watch over Faethor's castle and servants while gone, but after disobeying him, Faethor had him chained underneath the earth (leading to the events of the prior book). Yulian is creating thralls out of his family, and Thibor uses telepathy to tell him that Harry Jr. is a great enemy. Yulian sets out to kill the infant, and Harry informs E-Branch that Thibor has a piece of dead skin left behind, which could be used to further Yulian's mutation. E-Branch teams up with the current Russian head to destroy Thibor's remains and a "finger mutation" left behind in Castle Ferenczy. After destroying the remains of Thibor, Alec Kyle is captured by rogue Russian agents believing him to be a spy. With the assistance of Zek Foener they mindwipe him and steal his knowledge of British E-Branch and Harry Keogh. Afterwards Zek Foener learns she has been tricked and vows never to use her talents for the Russians again. As Yulian prepares to murder Harry Jr, the infant, using powers he learned form his fathers mind slips through the Mobius Continuum, to E-Branch HQ with Brenda while the dead rise to slaughter Yulian Bodescu. Before he goes Harry Jr. releases his fathers consciousness, which is drawn to inhabit the now mindless body of Alec Kyle. Enraged at what the Russians have done to Alec Kyle, Harry destroys the Russian HQ once more. It is unclear at the end of the Novel whether Yulian would have developed into "FULL" Wamphyri, however such seems likely as he had been able to shapeshift extensively among other talents that lesser vampires seldom possess to any great extent.
