Harry quit British E-Branch and devoted himself to his search, which soon became an obsession. Years passed and the Necroscope turned recluse, living in a rambling, ramshackle house some miles outside Edinburgh.

Then… E-Branch contacted him again. They were badly in need of Harry's help and guessed he'd be reluctant, but there was also a carrot. The Branch had a similar case on its hands: a Secret Service agent had gone missing, not presumed dead. Just like Harry Jr and his mother, so now a young spy had disappeared into thin air. The mindspies had reason to believe he was alive, but still they couldn't find him. Harry checked it out with the Great Majority, who denied that the missing man had joined their ranks. And yet E-Branch swore that he wasn't 'here' on Earth. So… where was he?

Could it be he was in the same place as the Necroscope's wife and child?

Eventually Harry's inquiries led him to the Perchorsk Projekt, a Russian experiment buried deep in a ravine under the Ural Mountains. In an attempt to create a force-field barrier as a counter to the USA's Star Wars scenario, the Soviets had accidentally blasted a 'wormhole' out of this space-time dimension into a parallel plane of existence. And in so doing they had also discovered the ancient source of all vampiric infestation of Earth! Things were coming through the Perchorsk Gate into our world. Unbelievable things — unbelievable except to the Necroscope and certain members of the British and Soviet E-Branches.

Through his contacts with the dead, and especially with the assistance of August Ferdinand Möbius, Harry discovered a second Gate and used it to venture into the world of the Wamphyri, whose skyscraper aeries gloomed gaunt and nightmarish over all Starside, the world where the vampire Lords held sway. There he discovered his son, grown now to a young man, but, alas, infected with vampirism!
