[1] David Sorrel has been sentenced to life in Long Barrow Maximum Security Prison on Dartmoor, following the murders of his wife and her lover, who are also beheaded.
David is dreaming about the night that he murdered his wife and her lover, in which he grins an insane smile, one which resembles the monster Grice's.
Hell is breaking loose in Long Barrow Prison as a guard runs through the blood-splattered corridors before being decapitated by one of the monsters.
Harry tells him that he was allowed to write a book about the prison once, giving him access to the internet where he discovered facts about the ventilation system, cellars, and exits.
But luckily the horribly mutated Harry has managed to fight off the transformation and kills him with a pole and tells the woman to make a run for it.
Suddenly, they realise the Sheeny has transformed into a creature and is trying to wreck the bio-weapon they brought with them to try and kill the TDI's.
He tells them that the Otherworld was created by extra-dimensional intelligence to try and force the creatures to evolve from their physical form to leave their Universe.
However, it turns out that human beings can make this evolutionary jump, and Sorrel tells them that he and the other light-beings will destroy all trace of mankind in the Otherworld to hide this fact from the extra-dimensional entities.
Sorrel confirms Harry's suspicion that he will have to be killed, to hide all evidence of mankind in the Otherworld, though he goes onto tell him he will probably become a light-being like himself.
Cramming their advanced technology into Sorrel when he died of Carbon monoxide poisoning to invade Earth, but failed when Jon Prentiss sacrificed himself.
