SPRING-HEELED JACK

1. Public Record

London, winter 1837-38. A figure in the lanes east of the city who rang gates, claimed to be a policeman, then threw off a cloak and showed a helmet, tight pale clothing like oilskin, eyes like red balls, and a mouth that put out blue and white flame. He tore at clothing with what Jane Alsop swore were metal claws, leapt walls that a man should not leap, and left a name the papers were already using: Spring-heeled Jack.

The case that put him in the police court is Bearbind Lane, Old Ford, 20 February 1838. About 20:45 a violent ringing. Jane Alsop, eighteen, went to the gate. The man outside said they had caught Spring-heeled Jack in the lane and needed a light. She brought a candle. He put it to his chest, spat flame, seized her by the neck and dress, and started on the gown. Her sister pulled her into the house. He kept ringing until he ran.

The Lord Mayor had already been receiving letters about a “suburban ghost.” After Alsop, the complaint was no longer folklore in a newspaper. It was an assault with named witnesses at Lambeth Street office.

For God’s sake bring me a light, for we have caught Spring-heeled Jack here in the lane.

2. Date of Incident

First press cluster autumn 1837. Alsop assault 20 February 1838. A second named attack on Lucy Scales in Limehouse followed days later: a jet of fire to the face, no claws this time. Later provincial copycats run for decades and should not be stapled to the 1838 core.

3. Location

East London fringe: Old Ford, Bow, Limehouse. Alsop house on a then-lonely lane between Bow and Old Ford. Approximate 51°32 N 000°02 W.

4. Official Narrative

Police treated it as a masked assailant. Rewards were discussed. No arrest that stuck. The fashionable early suspect - a young nobleman doing it for a wager - was never produced in a dock. Official narrative: dangerous hoaxer, not a demon. They still could not catch him on the night.

5. Witness Layer

Jane Alsop’s statement is the best page in the file because it was given next day, with her father and sisters present, and because the ruse is specific: he used the panic about himself as the password. Scales adds a second named woman and a different method. Together they describe a costume that could be built - oilskin, helmet, some kind of fire-spitter - and a physicality that the costume does not automatically explain, the walls and the speed.

He vomited forth a quantity of blue and white flame from his mouth, and his eyes resembled red balls of fire… his claws, which she was certain were of some metallic substance.

Frequent representations had of late been made to the Lord Mayor of the alarm excited by a miscreant who haunted the lanes and lonely places in the neighbourhood of the metropolis.

6. Recovery Logistics

No costume recovered. No chemical residue logged. The candle Jane handed over is the only object that definitely changed hands.

7. Assessment

A human assailant in a theatrical kit is the least strained reading of Alsop. The fire and the leaps are why the kit never quite closes the folder. Later spring-heeled figures in the Midlands and the North are mostly the name travelling. Keep 1837-38 London as the case and the rest as aftershock.

8. Materials & Remains

Court and press statements. No claws in a drawer. The oilskin is a description, not an exhibit.

9. Key Personnel

Jane Alsop - Primary assault witness.

Lucy Scales - Second named 1838 victim.

Mr Alsop and the other sisters - Immediate corroboration.

Lord Mayor / Lambeth Street magistrates - Official paper.

10. Aftermath

Penny dreadfuls ate him. The name outlived the man, which is how you lose a suspect. The 1838 statements are still sharper than anything written about him after 1870.

11. Current Archive Status

Status: Named 1838 assaults. Costume likely. Identity never fixed.

Confidence: High that Jane Alsop was attacked at her gate on 20 February 1838 by a man using the Jack panic as bait. High that a similar figure was already being reported that winter. Low that a single noble wager explains every leap. Low that a non-human reading is required by the court paper.

Filing note

This file starts at a garden gate and should be allowed to stay there. Jane Alsop answers with a candle for a man who says they have caught Spring-heeled Jack. He throws off a cloak, spits blue-white flame, tears the gown with metal claws. The later rooftop devil is a different drawing. Start at the gate.

He asked for a light. A human sentence, the sort you give a watchman. What he did with the candle is why the file is still open. That small request at the latch makes the flame colder than any penny-dreadful leap across a roof.
