The strange events began in autumn 1931, when the Irvings noticed an unusual animal in their farmyard, being, as Price’s correspondent described: “similar in appearance to a weasel, with small body, long bushy tail, flat nose, and yellow in colour”.[3] Oddly, this animal did not appear to alarm the chickens. Later, it was seen inside the house, as James Irving described: “This eerie weasel, as I thought he might be, then began to keep us awake at night by blowing, spitting and growling behind the matchboard partition of the lower rooms…”[4]
The entity quickly progressed to something more sophisticated. Having learned to mimic various animal noises, it then began to repeat nursery rhymes, and within a short while – having built up a sufficiently wide vocabulary – it could converse with the family. Its voice is said to have been loud, clear, and one or two octaves higher than a human’s. Other witnesses describe it as a “very high, screechy sort”.[5]
Initial news reports spoke of the ‘man-weasel’ farm,[6] and indeed, the entity itself, when asked who or what he was, would frequently reply: “I am the ghost of a weasel, and I will haunt you with weird noises and clanking chains.”[7] It was only later on that he described himself as “just a little extra, extra clever mongoose”.[8]
Newspapers printed stories about Gef, although when reporters visited the farm, he tended to disappear. Some considered him a poltergeist or a shape-shifter. It was later thought that the Irving's teenage daughter, Voirrey, provided the voice of Gef, but she never admitted to a hoax. Link
