One rainy but humid Wednesday evening in July 1909, a stranger entered the Lady of the Lake public house, at 41 Brownlow Hill, Liverpool, England.
The man wore a wide-brimmed floppy fedora, and a long dark grey over-coat and ordered a glass of imperial stout.
Two regulars, Mick McTiernan and Eddy O'Brien, tried to engage the stranger in conversation; querying why he wore a fedora on a warm summer night.
The stranger had a prominent aquiline nose, small darting eyes, and swept-back eyebrows that met in the middle.
He wore a distinguished dark Vandyke beard, and had long tapering fingers with well-kept, but pointy, nails.
"Think we're below you, do you?" Eddy touched the man's shoulder with his index finger, and it was a big mistake.
The stranger turned to face Eddy and spat a mouthful of imperial stout in his eyes.
Mick swung a punch, and the stranger moved his head back with lightning reflexes. Mick's fist caught the brim of the hat and sent it flying, revealing a strange sight.
The man had long pointed ears, and small horn-like appendages just above his eyebrows.
His eyes moved independently, like a lizard.
The barman had witnessed some fights, but the two punches by the stranger were the most powerful he had seen.
One rapid blow knocked out Eddy O'Brien, and the other sent his friend sailing across tables.
The stranger then shrieked with high-pitched laughter and jumped clean over the bar, almost hitting his head on the ornate ceiling mouldings.
People in the bar thought Spring-Heeled Jack was paying a surprise visit, for no human could exercise such incredible acrobatic skills.
There was a mass exodus as drinkers poured out onto Brownlow Hill.
The fiend stood on a man's shoulders, leapt onto a table, swung from a chandelier and then back-flipped out of the pub.
He ran at an incredible speed up Ainsworth Street and vanished into a labyrinth of courts.
The drinkers gradually filed back into the pub, and found an old plasterer named Longfellow, sitting serenely in the corner with a smile on his face. His glass of Irish whiskey was still intact.
He said over 20 years before he had seen the very same acrobatic madman at an old tavern in the Rainhill area.
Some called him the Galosher Man, among other names, and said he was what was known as Other-kin, strange-looking people who are the offspring of human and supernatural creatures.
Spring-Heeled Jack and various other bogeymen were Otherkin, according to Longfellow.
The Galosher Man - so called because of the strange boots he always wore - occasionally attempted to live among mankind by entering inns and even churches disguised as a human, but he was usually exposed
