A legendary early-Victorian London figure (>>> Urban Legends). He was (at first) a mysterious outlaw who attacked his victims while wearing a large helmet, a long black flowing cloak and tight-fitting white oilskin-like suit. His hands were claw-like, his eyes burned like coals, his ears were huge and his mouth spat blue flame. He was capable of jumping rooftops at a single bound. Guns didn't bother him. He made no noise at all. In early penny-dreadful appearances – like Spring-Heeled Jack, the Terror of London (circa 1870) – he was villainous, but he soon became in effect a Masked Avenger, defending the poor and helpless; this version stars in Philip Pullman's Spring-Heeled Jack (1989). In Tim Powers's The Anubis Gates (1983) SHJ is far more menacing. [JC]
