Necroscope

The hero of the Necroscope series – or antihero, as the story unfolds – is Harry Keogh. Keogh's grandmother was a Russian immigrant who settled in Great Britain. His father died when he was very young. His mother later remarried and was eventually killed by Harry's stepfather. During his early childhood Keogh lived with an aunt and uncle in County Durham in North East England. Keogh would eventually return to exact vengeance on his Russian stepfather.

While at school, being not particularly popular or academically inclined, Harry discovers his ability to speak to people who have died. He also, in most part due to this ability, shows great aptitude in the fields of mathematics and creative writing.

The author also puts forward the idea that death is not the end, and that whatever someone was or wished to be in life, he or she continues to be in death, within the restraints that death imposes. For example, a mathematician would continue perfecting his math, an inventor would keep inventing new things, and a psychic would continue to practice using their powers.

Not only can Harry speak to the dead (thus earning him their eternal admiration, almost amounting to worship), but he can also form a bond with them which allows them a degree of control over him when he permits. For example, when faced with a dangerous situation, Harry hands his mind over to the control of a former gym teacher who was an army sergeant, and learns martial arts skills. He does not forget what he learns, and continues to use this skill and many others throughout the series. In addition, if the dead are nearby and the physical situation permits, they will literally raise themselves up out of the ground and fight for him. This gives him powerful allies as, being dead already, they have nothing to lose and almost nothing to fear.

Harry is also able to teleport anywhere in the world via the Möbius continuum, which he learned from August Ferdinand Möbius. By employing advanced equations learned through his dead tutor and his intuitive mathematical mind, Harry can conjure a door in space and enter the Möbius continuum, he can then create another door to exit. There is no time in the continuum so teleportation is instant. Harry is also able to open a past or future time door and observe what may be, but he cannot appear there physically.

In total, Harry Keogh has 6 different ESP talents by the end of the first series of five books:

• Deadspeak: an evolution of his mother's talent as a psychic medium.[2]
• Teleportation: technically space-time manipulation, learned from August Ferdinand Möbius.[3]
• A 'mind-blanket': gifted by the deceased Norman Wellesly which completely blanks his mind out.[4]
• Telepathy: learned from the E-Branch telepath Trevor Jordan.[4]
• Locator: by connecting with another mind, Harry can locate and appear near them.[4]
• Resurrection-type Necromancy: by means of a spoken incantation, learned during a battle against the vampire Janos Ferenczy, Harry can bring the dead back to full animation.[4] Readers of H.P. Lovecraft's works will note that the same incantation from his works appears here. Lumley is well known for his extension of the Cthulhu mythos (the Titus Crow novels et al.), and this to some extent acts as a tie-in to Titus Crow universe and to the Mythos in general.

Son of Harry Keogh and his wife Brenda, Harry Jr. shows immense intelligence even as toddler and has even greater powers than his father.

Choosing to flee from Earth after attack by the vampire Yulian Bodescu, the baby Harry Jr., showing even greater mastery over the Möbius continuum than his father, transports himself and his mother to the parallel universe of Starside/Sunside and also back in time twenty years.

Living on Starside with his mother, Harry Jr. is vampirised by an 'infected' wolf and becomes Wamphyri and is named 'The Dweller in His Garden in the West' by the world's fearful inhabitants. Hiding his Wamphyri features behind a golden mask and black cloak – he shuns the Wamphyri lifestyle, instead using his immense willpower to hold his vampire at bay.

The Dweller forms an alliance with the Szgany Lidesci (the planet's gypsy-like humans) but becomes infamous among the Wamphyri of Starside because of his mysterious powers. Fearing him, they form an alliance to attack him at his garden in the mountains.

Severely injured during the battle, his vampire leech re-shapes his damaged body into that of a more simple entity, a wolf, to save both their lives. His injuries were immense, and with much less mass, rebuilding damaged tissue and bone was easier. The exception to this transformation was his hands, which he willed remain, so that the Szgany may know him, and so that he too would have a reminder of the man he once was.

The change removes his ability to use the Möbius continuum, leaving him with just Deadspeak and telepathy. His mind soon wanes and he loses touch with his humanity, preferring to take the company of his Starside/Sunside wolf brethren.

Son of Harry Keogh and a Szgany traveller woman Nana Kiklu, born in the vampire world of Sunside/Starside with his twin brother Nestor, Nathan is at first the quietest and most withdrawn of the two and is thought of as dumb by some of the Szgany tribe due to his lack of confidence, his stutter and unwillingness to speak, only talking to those closest to him.

Inheriting his fathers deadspeak powers Nathan hears the thoughts of the dead in his dreams but they refuse to talk to him, wary of him as they had been his father at the end of his life. He also communicates with three friendly wolves which talk to him telepathically while he sleeps, although not knowing why or understanding how Nathan takes them as just dreams. By the trilogy's end, it is revealed that they are the Dweller's pups, born with intelligence rivalling man, with their father's Deadspeak and sense of direction (the ability that Harry Jr/The Dweller used in finding the way to Sunside/Starside).

Everything changes for Nathan when his village on Sunside is attacked by Wamphyri, seeking his lost brother he leaves on a long journey of discovery taking him across the whole of Sunside/Starside. Becoming strong and confident, losing his stutter, and learning to use his long dormant telepathy while on his travels, he eventually returns to his Szgany clan before being taken by the Wamphyri and is thrown through a wormhole (gate) to Earth.

Arriving in a Russian base he escapes and is found by the British E-Branch who teach him of his heritage and his true father and more importantly Nathan finally learns the ways of teleportation via the Möbius continuum like his father.

With the help of British E-Branch Nathan returns to his own world and wages war on the Wamphyri.

Jake Cutter is not a blood relative of Harry Keogh but becomes a Necroscope when the world is once again threatened by the Wamphyri.

Apparently chosen by the spirit of the dead Harry Keogh, Jake is spotted and recruited by the British E-Branch where he is tutored and taught about Harry's legacy and deadspeak and eventually masters the Möbius continuum.

Also not of Harry Keogh's bloodline. While in mourning for his dead wife, Scott is struck by a fragment of Harry and becomes a Necroscope.
