The Great Amherst Mystery: Canada's Most Violent Poltergeist

In 1878, in the small town of Amherst, Nova Scotia, 19-year-old Esther Cox became the unwilling focus of what would become one of North America’s most famous and violent poltergeist cases. After suffering a traumatic sexual assault, Esther began experiencing phenomena that defied explanation: her body swelled grotesquely, objects flew through the air with lethal force, fires ignited spontaneously, pins materialized and stabbed into her flesh, and writing appeared on walls—most chillingly, the words “Esther Cox, you are mine to kill.” Over the course of a year, more than 100 witnesses—including doctors, ministers, police officers, and journalists—observed the phenomena firsthand. The case was investigated and documented by Walter Hubbell, an actor who lived in the house for weeks, later publishing “The Great Amherst Mystery” (1888), one of the first detailed accounts of poltergeist activity. The case established the pattern that researchers would see again and again: poltergeist activity often centers on a young person, usually female, who has experienced severe psychological trauma. The Great Amherst Mystery wasn’t just a haunting—it was a warning about what can happen when the mind breaks and something else moves in.

Esther Cox

Esther Cox was born in 1860 in Amherst, Nova Scotia, orphaned young, and raised in the crowded household of her married sister Olive and brother-in-law Daniel Teed on Princess Street. The home was full—Daniel and Olive, their two children, Esther’s sister Jennie, and two more brothers all shared the cramped space, leaving little room for privacy. Esther worked at a local shoe factory and was by all accounts an ordinary young Victorian woman, described as nervous and excitable, prone to anxiety, but not mentally ill. Nothing about her life was unusual until August 1878, when everything changed.

That month, Bob McNeal, a family acquaintance, lured Esther into a carriage and drove her to an isolated location where he attempted to sexually assault her. The attack was interrupted before completion, but the damage was done. Esther escaped physically, but she was psychologically shattered. McNeal fled town and no prosecution was ever pursued. The family kept the incident quiet, as Victorian shame prevailed, and Esther suffered alone. In the weeks that followed, she became withdrawn, nervous, and frightened. Within weeks, strange things began to happen. The connection between the trauma and what followed was unmistakable.

The Phenomena Begin

One night in September 1878, Esther and Jennie were sharing a bed when something moved in the bedding. They assumed it was mice, but then the bed began to shake violently with no explanation. Days later, Esther’s body began to swell—her face, hands, and whole body grotesquely inflated, as though something inside were trying to burst out. The sight was terrifying to witness.

Dr. Carritte was called to examine Esther but found no physical cause for the swelling. As he watched, loud banging erupted from nowhere, the bedding flew off the bed on its own, and then, most chillingly of all, writing appeared on the wall: “ESTHER COX, YOU ARE MINE TO KILL.” The letters scratched themselves into the plaster as those present watched, forming one by one as if traced by an invisible hand. The doctor fled in terror, though he returned the following day to witness still more.

The activity escalated rapidly. Objects flew through rooms, furniture moved on its own, loud banging sounded at all hours, and matches appeared and lit themselves, starting spontaneous fires on beds, clothing, and walls. Pins materialized in the air and stabbed into Esther’s face and arms, appearing from nowhere and targeting her specifically. The violence was personal—something hated Esther Cox. Knocking, banging, and scratching filled the house, and occasionally voices were heard, naming themselves “Bob,” “Maggie,” and “Peter,” leaving investigators to wonder whether multiple entities were present or one was pretending.

The Investigation

Dr. Thomas Carritte, a respected local physician who was initially skeptical, became convinced that something supernatural was occurring after witnessing objects move without physical cause, writing appear on walls, Esther’s body swell and deflate inexplicably, and temperature drops in rooms. He documented his observations extensively and concluded: “I am unable to explain the phenomena I have witnessed in that house. There is something present that I do not understand. It is not trickery—of that I am certain.”

He was far from the only witness. Reverend R.A. Temple, a Baptist minister, along with multiple doctors, police officers, journalists, neighbors, and visitors—over one hundred people in total—confirmed that the phenomena were real and not the result of fraud or hysteria. Multiple people saw the same things, physical evidence existed, and something dangerous was clearly present.

Walter Hubbell, a professional actor who heard about the case, traveled to Amherst to investigate and ended up living in the house for weeks. Objects were thrown at him, his umbrella flew across the room, his chair moved while he sat in it, and he witnessed the fires and the writing appearing on the walls. He watched Esther suffer and documented everything he observed. His subsequent book, “The Great Amherst Mystery” (1888), included detailed witness statements, diagrams of the house, and a comprehensive timeline of events. It became a classic in paranormal literature and one of the first thorough accounts of poltergeist activity.

The Fires

The fire-starting was among the most dangerous aspects of the case. Fires ignited without any identifiable cause in multiple locations throughout the house. Lighted matches dropped from the air onto beds, clothing, and walls with no physical source. The entity, it seemed, wanted to burn.

The pattern was consistent: fires started when Esther was present, often when she slept. The house was in constant danger, and bucket brigades became a routine part of daily life. The family lived in perpetual fear of burning alive. In one notable incident, a dress hanging in a closet burst into flames while Esther was across the room, witnessed by multiple people. The fire was extinguished quickly, but the message was clear.

The fire-starting eventually led to devastating consequences for Esther. When she went to work for a neighbor named Arthur Davison, his barn burned to the ground. Esther was accused of arson, tried, convicted, and sentenced to four months in jail. The question of her guilt remained deeply controversial—she had no motive, and multiple fires had occurred before that were unanimously attributed to the poltergeist. But the court did not believe in ghosts, and Esther paid the price for whatever force had attached itself to her.

The Resolution

Following Esther’s release from jail, the phenomena decreased dramatically. The entity seemed satisfied, or exhausted, or simply moved on. The terror was ending. Theories about why it stopped vary—Esther married and moved away from Amherst, and perhaps the trauma was finally processed, or perhaps the entity departed on its own.

Esther went on to marry twice and have a son. She lived a relatively normal life until her death in 1912 at the age of fifty-two, never experiencing poltergeist phenomena again. She rarely discussed the case, finding the memories too painful, and preferred to forget the year of terror that had defined her youth. The poltergeist was done with her, and she had survived.

Understanding the Phenomena

The Great Amherst Mystery displayed all the classic features that researchers would come to associate with poltergeist cases: a young female at the center, recent psychological trauma, physical manifestations, escalating violence, multiple witnesses, and gradual resolution. What made the Amherst case unique was the writing on walls, the named entities, the direct death threats, the fire-starting, the legal consequences for Esther, and the thoroughness of the documentation.

The trauma connection is central to modern understanding of poltergeist activity. Researchers have observed that poltergeists often follow experiences of sexual assault, violence, or loss—the psychic energy generated by trauma must go somewhere, and it manifests externally, most commonly in young people. Esther’s case fits this pattern precisely: severe sexual trauma followed by the immediate onset of phenomena, with Esther herself as both the target and, possibly, the unknowing source.

Skeptics have advanced several explanations. The fraud theory suggests Esther faked everything for attention or sympathy, driven to desperation by the assault. However, this theory struggles to account for the sheer number of witnesses, the volume of physical evidence, the fact that phenomena occurred while she slept, and the fires that endangered her own life—an elaborate deception seems beyond the capabilities of a traumatized teenager. The hysteria theory proposes that Esther’s mind created illusions and that mass hysteria affected witnesses, but this fails to explain the physical evidence that remained after events: writing on walls, burned materials, and moved objects that were independently observed by multiple people.

Among believers, interpretations split between those who saw a demonic entity that attached to Esther and fed on her trauma, and those who favor the psychic theory of Recurrent Spontaneous Psychokinesis (RSPK)—the idea that Esther’s unconscious mind generated the phenomena, her trauma expressing itself physically. Under this interpretation, Esther was the poltergeist, unknowingly.

The Legacy

The Great Amherst Mystery remains one of the most documented early poltergeist cases and set standards for investigation that influenced future researchers. Hubbell’s book became a foundational text, and the case is still studied and referenced constantly in paranormal literature. It established the trauma-poltergeist connection, documented the pattern of escalation followed by eventual resolution, and demonstrated the critical importance of thorough documentation and multiple witnesses.

Modern researchers view the case as one in which genuine phenomena occurred, triggered by trauma through an exact mechanism that remains unknown. Whether Esther was the agent, the victim, or both continues to be debated. The mystery endures, but what the case teaches is clear: poltergeists represent real experiences, whether supernatural or psychological in origin. Something happens in these cases, documentation matters, context matters, and victims deserve compassion.

Visiting Amherst

The original house on Princess Street no longer stands, having been demolished long ago. A marker indicates the location, but nothing paranormal remains—the entity left with Esther. Amherst today is a small Nova Scotia town of approximately ten thousand people with an industrial heritage. The case is local legend, embraced by some and forgotten by others. Occasional walking tours cover the Amherst Mystery, providing historical context, visiting the house’s location, and including other local hauntings, with interest varying by season.

The Terror That Time Forgot

Esther Cox survived. She outlived the entity that tormented her, the trauma that summoned it, and the infamy that followed. She married, raised a child, and died an old woman in relative peace.

But for a year of her young life, she was the center of something inexplicable. Objects flew. Fires burned. Words appeared on walls, threatening her death. Over a hundred people watched and couldn’t explain what they saw.

The house on Princess Street is gone now. Amherst is just another small Nova Scotia town. The Great Amherst Mystery has faded into paranormal history—a chapter in books, a footnote in research papers.

But the pattern Esther established still repeats. Every few years, somewhere in the world, a young person emerges from trauma to find that objects move on their own, fires start without cause, and something unseen seems determined to destroy them.

The trauma-poltergeist connection that Esther Cox demonstrated in 1878 remains one of the most consistent patterns in paranormal research.

Whatever followed Esther, whatever wrote her name on those walls, whatever wanted her dead—

It wasn’t the last of its kind.

---

“Esther Cox, you are mine to kill.” Writing on walls. Fires from nowhere. Pins from the air. The Great Amherst Mystery: Canada’s most violent poltergeist, born from trauma, documented by over 100 witnesses, and finally—mercifully—ended. The house is gone. The girl survived. The mystery remains.
