Having once risked everything precious to him to halt King Lud's progress from the ancient bowels of London to the city's modern streets, teenage Paul Rector knows his task is far from over. Paul also knows that, like his brother John and his great uncle Harry, he is both demon and man. Will it be fate that decides which side wins out? To find out, Paul takes Hell's Underground back to London of the Blitz in World War II and becomes involved in defeating Harry Rector's plot to assassinate Prime Minister Churchill. His main weapons are fire and fear. Along the way, he learns more about the Rector curse and once again endangers not only his own life, but that of the people he comes to regard as a second family.

Late one night after a strange tube journey to Whitechapel in East London, Paul makes a new friend, John Redman - daring and enigmatic, just as Paul longs to be, away from his cloying mother (his only family - so he thinks). Redman charms Paul at once, but also a girl called Jude they meet on a night about town. A few days later, Paul learns that Jude has mysteriously died, and Redman has disappeared. Shortly after that, one of Paul's teacher dies suddenly - frightened to death - near where Jude's body was found. A link for sure. And Paul feels implicated, because both victims were known to him. He senses Redman, who comes and goes as it suits him, is involved as well. His new friend is dangerous. But so, we learn, is Paul. In uncovering the truth about Redman he learns shocking facts about himself. There's an evil curse loose in his family and Paul is the latest inheritor. The spree of death - camouflagued as copycat Jack the Ripper-style murders - will continue until Paul confronts the demon in himself head on.
