Spring-Heeled Jack: Cryptid or Conspiracy?

Two hundred years ago, London had no streetlights. Walking home on winter nights meant braving pitch-black alleyways. When the Scales sisters hurried along Green Dragon Alley one evening in 1838, they spotted a tall man in a cloak ahead of them. As they drew near, he whipped around and exhaled blue fire—bright indigo flames that blinded one sister, singed her eyebrows, and knocked her to the ground screaming. Then the attacker sprang into the air, rising to the rooftops before landing a block away and bouncing over a high wall out of sight.

This was not the first such attack. The same mysterious figure had slashed women's skin, ripped out their hair, forcibly kissed and undressed them, and even thrown a woman into the river. Some said it was a demon. Others believed it was a band of costumed elites conspiring to commit crimes without consequence. Still others thought it was an alien. But everyone called him the same name: Spring-Heeled Jack.
