A council house was haunted by a poltergeist, causing moving furniture, knocking sounds, and levitation of children.
Moderate for documenting the reports, investigator interpretation, photographs, later lectures, and skeptical objections; weak for paranormal causation. Some activity was admitted or observed to be staged. Complete original field tapes and committee archives are not packaged.

Investigative Assessments

"The reported claim remains worth testing against the record: A council house was haunted by a poltergeist, causing moving furniture, knocking sounds, and levitation of children. The strongest documented reasons to keep the file open are: Society for Psychical Research Psi Encyclopedia: Enfield Poltergeist: Details the timeline, names of witnesses, and scientific tests (laryngograph, weight measurements, psychiatric evaluation) conducted on Janet Hodgson.; Skeptoid Podcast Episode 527: Conjuring Up the Warrens: Provides a critical examination of the levitation photographs, the copying of Matthew Manning's teapot tricks, and the co-dependent relationship between Maurice Grosse and Janet Hodgson.. Key unresolved lead: Why did investigators fail to implement rigorous controls after repeatedly detecting the children playing tricks?"
"Evidentiary limitations: Moderate for documenting the reports, investigator interpretation, photographs, later lectures, and skeptical objections; weak for paranormal causation. Some activity was admitted or observed to be staged. Complete original field tapes and committee archives are not packaged. Note that: Society for Psychical Research Psi Encyclopedia: Enfield Poltergeist fails to support: Does not provide objective forensic proof of paranormal activity, and acknowledges that the children admitted to faking some of the phenomena.; Skeptoid Podcast Episode 527: Conjuring Up the Warrens fails to support: Does not contain original physical measurements or new eyewitness interviews from 1977.. Documented contradiction: While Janet Hodgson claimed the 'Bill Wilkins' voice was entirely paranormal, laryngograph and ventriloquism tests indicated it could be replicated via venting techniques or ventricular fold tension (plica ventricularis). Leading conventional hypothesis: Adolescent trickery and attention-seeking behavior by Janet and Margaret Hodgson, who admitted to faking some events."

Case Summary

A detailed parapsychological and skeptical investigation of the alleged poltergeist disturbances at 284 Green Street, Enfield, London, between 1977 and 1979. The case involved reports of knocking, flying objects, shifting furniture, vocal mimicry, and alleged levitation, primarily centering around eleven-year-old Janet Hodgson. Long-term studies were conducted by Society for Psychical Research investigators Maurice Grosse and Guy Lyon Playfair, while other SPR members and skeptical analysts concluded the phenomena were the result of adolescent trickery, attention-seeking behavior, and exaggeration. This dossier evaluates the primary records, the testimonies, and the structural co-dependencies of the investigators and the family.

Doubtful News: The Conjuring 2 (UPDATED)

Analyst rating: High authenticity for its inclusion of details from investigator Maurice Grosse's files and correspondence.

“Tom Ruffles looks into Maurice's files and finds WAY more info on this. Seems the Warrens did meet with the family and interview them... According to letters from Grosse's files, they MAY have spent at most 4 days there.”

Relationship to claimDeconstruction of the commercialized narratives surrounding the case.
Authenticity assessmentWritten by science writer Sharon A. Hill, incorporating research on Maurice Grosse's letters from the SPR files by Tom Ruffles.
What this supportsDocuments that the Warrens spent at most four days at the Enfield house, visited uninvited, and competed with SPR investigators to frame it as demonic for commercial purposes.
What it does not supportDoes not prove the complete absence of physical tricks by the children, but rather reinforces their presence and the commercial interests of the Warrens.

Documented Timeline

  • 1977-08-31: Janet and John Hodgson report shuffling sounds in their bedroom; mother Peggy Hodgson hears knocks and witnesses a chest of drawers slide 18 inches across the room. Neighbours Vic and Gary Nottingham witness further knocks.

  • 1977-09-04: Daily Mirror reporter Douglas Bence and photographer Graham Morris visit the house; Morris is struck by a flying Lego block.
  • 1977-09-05: Maurice Grosse of the Society for Psychical Research (SPR) visits the house and initiates a long-term investigation.
  • 1977-09-12: Guy Lyon Playfair joins the investigation, co-authoring the research with Grosse over the subsequent year.
  • 1977-12: An anomalous, deep masculine voice begins to emanate from Janet Hodgson, identifying itself as 'Bill Wilkins' and uttering swear words and biographical claims.
  • 1977-12: Anita Gregory and John Beloff of the SPR visit the house; Gregory concludes that the children are playing tricks and manually bending spoons.
  • 1978-05: The SPR establishes a committee (Barrington, Pincott, Hallson, and Stiles) to review Grosse and Playfair's investigation.
  • 1978-06-06: Ed and Lorraine Warren visit the house unannounced for a brief 4-day period, recording tapes and proposing book and movie deals to Playfair.
  • 1978-10: Grosse and Playfair conclude their active, continuous on-site investigation.
  • 1980: Guy Lyon Playfair publishes 'This House is Haunted', which is met with strong skepticism from parapsychologists like Anita Gregory and skeptics like Melvin Harris.
  • 2011: Janet Hodgson publicly admits in a newspaper interview that she and her sister Margaret faked about 'two percent' of the occurrences to test the investigators.

Named Participants and Roles

  • Peggy Hodgson: Mother of the family who reported the disturbances and maintained their anomalous nature until her death in 2003.
  • Janet Hodgson: The 11-year-old focus of the disturbances who was photographed jumping off her bed and admitted to faking a small percentage of the activity.
  • Margaret Hodgson: The 13-year-old sister who was also involved in some of the phenomena and vocal mimicry.
  • WPC Caroline Heeps: Police officer who signed a statement confirming she saw a chair slide across the living room floor.
  • Vic Nottingham: Next-door neighbour who entered the house and heard unexplained knocking.
  • Maurice Grosse: Lead SPR investigator who spent over a year on-site and remained convinced of the phenomena's authenticity, motivated in part by his deceased daughter.
  • Guy Lyon Playfair: Co-investigator and author of 'This House is Haunted' who defended the parapsychological reality of the events.
  • Anita Gregory: SPR member and investigator who visited in December 1977 and concluded the events were a hoax.
  • Douglas Bence and Graham Morris: Daily Mirror journalist and photographer who witnessed thrown toys.

Contradictions and Record Conflicts

  • While Janet Hodgson claimed the 'Bill Wilkins' voice was entirely paranormal, laryngograph and ventriloquism tests indicated it could be replicated via venting techniques or ventricular fold tension (plica ventricularis).
  • Photographs presented as evidence of levitation show Janet Hodgson in mid-air with body positions (such as bent knees or active jumping posture) consistent with jumping from her bed.
  • The children claimed to have no control over the events, but the phenomena consistently failed to occur when they were under direct observation or secret video recording.
  • The Warrens claimed to have played a central role in resolving the case, but SPR investigators Maurice Grosse and Guy Lyon Playfair documented that the Warrens spent at most four days at the house uninvited and were primarily focused on commercial exploitation.

Conventional Explanations

  • Adolescent trickery and attention-seeking behavior by Janet and Margaret Hodgson, who admitted to faking some events.
  • Vocal mimicry using plica ventricularis to produce a deep masculine voice.
  • Gymnastic jumping off the bed captured by still cameras at the peak of the jump to simulate levitation.
  • Confirmation bias and co-dependency by Maurice Grosse, who was grieving the recent death of his daughter also named Janet.

Missing Evidence

  • Uncut, continuous video recordings of the physical objects moving from a stationary state in an empty room.
  • Contemporaneous audio recordings of the 'Bill Wilkins' voice where the subject's mouth was completely and verified sealed without any vocal tract movement.
  • Independent physical or forensic trace evidence of the force that reportedly wrenched the built-in iron fireplace from the wall.
  • Complete unedited Maurice Grosse field-tape archive; attached audio is later public lecture material.
  • Full SPR committee file and signed police statement in redistributable digital form.

What Remains Unresolved

  • The precise mechanism and motivation of the minor anomalies reported by physicist John Hasted, such as transient weight-increase signals when Janet was strapped to a couch.
  • The exact source of the details about former tenant Bill Wilkins' death uttered by Janet's voice, though skeptics suggest the information was accessible via neighborhood gossip or municipal records.

Investigative Hypotheses

  • A hoax staged by the children in the household for attention and parental reinforcement.
  • Misinterpreted natural sounds, exaggeration of minor incidents, and co-dependent reinforcement by investigators.
  • Genuine paranormal or poltergeist activity manifesting as recurrent spontaneous psychokinesis.

Open Questions

  • Why did investigators fail to implement rigorous controls after repeatedly detecting the children playing tricks?
  • Can the anomalous voice recordings be fully explained by venting techniques or ventricular fold speech patterns?
  • How did the psychological dynamics of the fatherless household influence the initiation and prolongation of the phenomena?
