History, ghostlore, and the psychology of fear converge in the true story of the Mulmur Hills Poltergeist.

In the aftermath of the Great War, the Dobson family retreats to a quiet farm in Mulmur, Ontario, seeking peace from urban life. Their tranquility is shattered when terrifying horse mutilations signal the presence of an unseen thing. In time, the terror moves indoors, turning the farmhouse into a battleground of inexplicable phenomena: phantom knocks, shaking floors, and objects that defy gravity. When the disturbances take a darker, more violent turn, the Dobsons flee. Their ordeal draws journalists and thrill-seekers to the now-famous “Spook Farm.”

As rumours of family intrigue, buried secrets, and supernatural forces swirl, spiritualist investigator Ivan Hutchins joins the Dobsons to unravel the mystery through séances and first-hand inquiry. The story unfolds against a wider tapestry of rural Canadian poltergeist cases, comparing the Dobsons’ ordeal with other hauntings and the patterns they share.

This forgotten chapter of Canadian paranormal history explores why such occurrences echo throughout our folklore, our fears, and our enduring fascination with the unexplained.
