Two of London’s urban legends are given relatively detailed sub-chapters. The odd rather comical figure of Spring-Heeled Jack, who terrorised London during Queen Victoria’s reign and the Highgate Cemetery Vampire of the swinging sixties and seventies. If Hammer was to make a nostalgic homage to its vampire films of the era, then the supposedly Highgate undead and their real life amateur vampire hunters would be fertile material to base it on. Highgate’s Western Cemetery is certainly a wonderfully eerie locale, with its overgrown gravestones and dilapidated vaults-one of London’s genuine hidden areas of potent magic.
As a mere starting point into the labyrinth of London’s occult past (and present) this will do fine, but for more serious investigators though read Sinclair, Ackroyd et al.
