Frontiers of the Unknown

Andrew MacKenzie examines reported cases gathered under the methods and questions of psychical research, concentrating on prophecies, apparitions and poltergeists. The material ranges from individual experiences to investigations of incidents that attracted sustained attention, presenting competing explanations rather than treating paranormal claims as settled fact.

Among the cases discussed is the reported appearance of a dancing girl at One Tree Hill in south London in 1948. The closing account concerns the Fenland Poltergeist at Hannath Hall in Cambridgeshire, where witnesses described unexplained noises and sightings of a small fair-haired boy. Published in 1968, the book belongs to MacKenzie’s early studies of psychical-research cases and reflects his interest in assessing reported evidence.
