At a farm in the Dalby district of the Isle of Man, James Irving and his family said that an unseen visitor had learned to speak. The voice became known as Gef, the alleged talking mongoose, or the Dalby Spook. Its reported conversation was sometimes playful, sometimes threatening, and unusually full of everyday detail. Yet the surviving investigation contains a sharp division between the family’s accounts, visitors’ reports and physical material that could actually be examined.
From noises behind the boards to a speaking animal
The fullest readily accessible contemporary investigator’s narrative is chapter VI, pages 85–97, of Harry Price’s Confessions of a Ghost-Hunter (1936). Price explains that a woman on the island first contacted him in the winter of 1932. He then corresponded with Irving. Much of the early story in this chapter therefore comes from letters sent to Price, rather than events he witnessed.
Irving described a small yellowish, ferret-like creature with a bushy tail. The household initially heard barking, growling and blowing behind its wooden wall lining. Attempts to remove the supposed animal failed. Irving said that he began making animal calls and that the noises answered him accurately. His daughter Voirrey then tried nursery rhymes. According to the family, these too were repeated, and a clear, very high voice became part of household life.
The creature was more often heard than seen. Price’s account describes fleeting glimpses and a particularly close relationship with Irving’s wife and daughter. The family supplied a growing biography: Gef supposedly came from India, accepted food, accompanied journeys while keeping out of sight and left dead rabbits for the household. Price also reproduced claims of songs, unfamiliar languages and knowledge of distant events. These are records of what Irving told the investigator; the chapter supplies no controlled demonstration of those abilities.
The visitor who heard a voice
Price sent a preliminary investigator, identified in this book only as Captain X. He dates the captain’s arrival to 26 February 1932. After a quiet first evening, the visitor was leaving when he heard a shrill voice. Returning inside brought silence. The next day he waited again. Price’s report describes a packing-case needle striking a teapot and, later, a voice upstairs where Mrs Irving and Voirrey were situated.
The captain tried to approach the upstairs room, but a loose stair tread caused a noisy fall. The voice stopped. This was an interesting hearing report, but the account did not establish a visible animal as its source. It also lacked a repeatable test that excluded the people in the house. Price’s published narrative leaves those limitations apparent even while treating the visitor as a capable observer.
A further visit began on 20 May 1935. The captain reported a call in the dark and a demonstration involving coins. In the family’s version of that game, coins were placed outside and Gef announced whether they showed heads or tails, watching through an opening. Price noted that the answers were sometimes correct. This description is considerably narrower than a claim that the creature unfailingly read concealed information.
What the hair examination found
In March 1935, material said to be Gef’s hair reached the captain and then Price. The alleged collection had not been witnessed by the examiner: Irving said that Gef left hair from his back and tail in an ornament on the mantelpiece. Price sent the samples to Julian Huxley, who passed them to F. Martin Duncan for identification. Page 91 reproduces Duncan’s conclusions and describes his comparisons.
Duncan examined the hairs microscopically against material of known origin. He excluded mongoose, several small mammals, and sheep, goat and cow. He thought the specimens probably came from a long-haired dog or dogs. His reasoning involved the structure of the cuticular scales and the medulla, with comparisons including wolf and collie hair. He also found no root bulbs and considered that the hairs had been cut. Further photomicrographs compared the material with cocker spaniel and setter hair.
This was a concrete adverse result for the claim that the samples established a mongoose. Its reach should still be stated carefully. The examiner assessed the submitted hairs, whose collection was reported to him. That does not identify the source of every voice or explain who placed the material in the ornament. During his later visit Price encountered Mona, the family’s collie sheepdog, and explicitly raised the possible connection. His chapter treats that connection as a question rather than a witnessed substitution.
Price and Lambert’s silent visit
Price travelled to the island with R. S. Lambert, editor of The Listener, on 30 July 1935. Irving had warned that Gef was absent, but they kept their arrangement. They visited the farmhouse that night, questioned the family and waited until midnight. Mrs Irving appealed to Gef; Price asked for speech, a scratch or any other response. None came.
They returned the next afternoon and stayed through another evening. This allowed Price to inspect the wooden lining, openings and concealed spaces. He described a gap behind the panels and a boxed partition associated with Gef. He considered that the lining could carry a voice through the house, making it difficult to judge where the speaker stood. This was an observation about the building’s potential acoustics, rather than a demonstration that he had caught anyone making the reported sounds.
Neither visitor heard or saw Gef during these sessions. Price records one shrill voice that startled him while waking at his inn, but immediately identifies its source as the innkeeper’s parrot. It should not be extracted from the surrounding passage and counted as an encounter with the mongoose. The family’s later explanation that Gef returned as the investigators departed was another report received afterwards, not something Price and Lambert observed.
Later research and the limits of a verdict
Price says that impressions of paws and teeth subsequently arrived in plasticine. This chapter records their receipt, without providing a full laboratory assessment. His unanswered questions about motive also deserve separation from the material tests: an investigator’s difficulty explaining why someone might stage an event is not evidence that an animal spoke.
Christopher Josiffe’s archival investigation for Fortean Times 269 identifies the captain as James Dennis and follows letters in the Harry Price and Society for Psychical Research collections. It also discusses problematic impressions and photographs, differing assessments by Price and Nandor Fodor, and Voirrey’s later denial of a hoax in a 1970 interview. Those later statements and archival citations broaden the history; they are not fresh demonstrations of the alleged creature. Josiffe’s article is the route consulted here for that later material, rather than the original interview or every manuscript it cites.
The University of Maryland, Baltimore County’s Garrett Collection overview adds an important qualification about Fodor’s stay: he did not see or interact with Gef himself. Its catalogued papers and photograph document an investigator’s engagement with the case, not a captured talking animal.
Gef’s historical interest lies in that unusually detailed paper trail and the contrast between abundant reported conversation and limited independently testable evidence. The hair result undermined one proposed physical identification; the silent 1935 visit prevented the investigators from testing the central claim. Neither warrants diagnosing the family or assigning an unproved role to a particular person. This account identifies only the broad Dalby district, gives no private-property pin and offers no route to the former farmhouse.
For another animal-like presence preserved through a different kind of record, read Tchi-cô, Guernsey’s Tower Beast. That collected tradition should be distinguished from Gef’s correspondence and investigator visits; resemblance between stories does not establish a common cause.
