Spring-Heeled Jack

Spring-Heeled Jack was the terror of Victorian London, a leaping fiend first reported in the late 1830s who haunted the popular imagination for decades afterwards. Witnesses described a tall, cloaked figure with burning red eyes and clawed hands, who breathed blue or white flame into his victims' faces and then bounded away over walls and rooftops with impossible, spring-loaded leaps. He was said to fall upon lone travellers — especially young women — before vanishing into the dark.

The panic spread through the newspapers and the penny dreadfuls until Jack became a fixture of cheap Victorian fiction, half bogeyman and half anti-hero. Theories at the time ranged from a prankster aristocrat to an outright demon, and no culprit was ever found. Spring-Heeled Jack endures as Britain's first great urban legend — a monster born not of the old countryside but of the gaslit city, and one of the earliest to be spread by the mass-printed sensation of the age.
