Dissected and Displayed After Hanging: What She Threatened Was Order, Not Money
Mary Bateman, an 18th-century fraudster, worked through fortune-telling and a poisoned pie — not for the money, but for the pleasure of control. Her cons landed precisely on what people wanted to believe, and after her death her body was still put on display, exposing how much a society feared anyone who upended its order.

Once the con artist blends into the crowd, magic's tacit bargain collapses
In the 1740s, a magician announced he would climb inside a bottle on stage at the Haymarket Theatre in London. The audience paid for tickets, expecting to suspend disbelief and enjoy an ingenious deception. But the performer never appeared, the crowd rioted at having been made fools of, and soldiers were eventually called in to put it down. Maddie points out that up to then there had been a tacit bargain between magic acts and their audiences: what happened on stage was a safe illusion, and the audience played along knowing full well it was fake. The moment the trickster broke that contract and melted into the crowd — becoming any stranger at all — every kind of trust stopped working. The episode reads as a metaphor for the era: all the settled rules were being rewritten.
— Maddy PellingShe was not short of money; what the con bought her was private control
After a mill fire, a pregnant Mary went door to door collecting bandages for the hospital, then turned around and sold every one of them. She was not short of money: her husband John was a wheelwright with a respectable income and a place in the militia. Maddie stresses that Mary's behaviour came out of a craving for private control, not an economic motive. She was skilled at using her pregnancy to win trust, at reading other people's fears, at offering comfort that seemed uncannily precise — and then destroying them completely. That pattern of manipulation runs through her whole life, and foreshadows the far graver crimes that followed.
— Maddy PellingThe con does not end in money; it ends in a pie laced with arsenic
Rebecca Perigo was chronically unwell, and Mary claimed the cure required spells worked through an intermediary, a Miss Blythe, luring the couple into handing over nearly everything they owned — a new bed, hams, gold coins. When William grew suspicious, Mary's final instruction was that they eat a pie with a powder mixed into it, then take honey to cover the bitterness. Rebecca ate a few mouthfuls, then was rolling on the floor vomiting, and died in agony days later; William survived because he took only one bite. He set a trap to lure Mary in, and she was carrying a small bottle of arsenic on her person, with several of her victims' possessions found in her house. At that point the con had escalated from psychological manipulation to lethal poisoning.
— Maddy PellingThe letter she told him to burn became the evidence that hanged her
At trial William produced the letters Mary had written him — she had told him to burn them after reading, but he kept them, and they became the strongest physical evidence against her. Several doctors examined the remains of the pie and the vomit; one of them even had a heart attack in the courtroom. Sentenced to hang, Mary tried ‘pleading the belly’, and the judge closed the court so that women present could examine her; the conclusion was that she was not pregnant. A prison keeper recalled her nursing her baby one last time, handing the child to her husband, and walking to the gallows. Mary was still lying up to the moment she died, but the chain of evidence could no longer be overturned.
— Maddy PellingHanging her was not enough; she had to be boiled into an exhibit
After Mary was hanged, her body was taken back to the anatomy school in Leeds, where the anatomist William Hay charged admission for three days, took the corpse apart in front of the crowd, and held up her womb to announce there was no baby in it; spectators joked that the heart wasn't black enough. Her remains were boiled and then exhibited, and her bones stayed museum exhibits until 2015. Visitors queued to touch the bones, afraid she would come back for revenge. Maddie argues that this extreme treatment shows she had shaken the hierarchical order of an emerging capitalism, and so had to be erased entirely, not merely executed.
— Maddy PellingShe made a living by defying the system, so the system had to erase her
Maddie points out that Mary feels strangely modern — reading weaknesses, offering hope, impersonating authority, exactly like plenty of con artists today. She was able to live inside the social system by working against it, and that is precisely what threatened a consolidating structure of capitalist power. So she was dissected, boiled and publicly displayed, to eliminate her symbolic threat. It exposes the era's fear of things running out of control: when society changes too fast, people look for an outlet in irrational explanations, and Mary was both a product of that demand and its scapegoat.
— Maddy PellingThe con artist isn't selling a product; it's hope reality can't supply
A listener, Stuart, describes his aunt paying $15,000 for a ‘magic box’ built out of a low-spec computer, on the grounds that expensive meant good. Maddie's reading is that the most powerful thing about con-artist stories is that they offer hope reality cannot deliver, while dressing themselves in authority and expertise. She notes that in the Enlightenment the definition of knowledge and the question of who held authority were both changing radically, and ordinary people found it hard to tell the difference; the modern internet amplifies the danger of that imitation of authority. When someone is drawn to the certainty a stranger projects, that is usually the moment they are most vulnerable.
— Maddy PellingThe deadliest forgery proves the expert was right all along
Tim uses the Van Meegeren case to show how precisely a con can be aimed at its target. The art critic Abraham Bredius had believed all his life that Vermeer went to Italy and was influenced by Caravaggio, but the evidence was thin. Van Meegeren painted a Caravaggesque Vermeer, letting Bredius see his own long-held theory confirmed — and so fooled the ultimate authenticator. Tim stresses that this is less plain forgery than ‘pressing a button’: it proves the other person has been right for their entire life. Anyone can be brought down by their own background and blind spots, and that is exactly what makes scams so hard to guard against.

And suddenly the trickster can be anyone, and the gloves are off, essentially, and this opens the gate for all kinds of chaos.

She was able to make a living actively working against it, and for that she is taken apart and destroyed and obliterated.

I think it's got to be that it offers people hope.

That story is the contract. Van Megran was a Nazi.
