Between 1993 and 1998, four people held a physical mediumship circle that produced incredible evidence in over 500 sittings. Their work was conducted in a number of international locations, including Germany, Ireland, the Netherlands, Spain (Ibiza), Switzerland, and the USA. Among the investigating teams were electrical engineers, astrophysicists, criminologists, psychologists and mathematicians as well as three seasoned investigators from the Society for Psychical Research.
Among the remarkable phenomena the group experienced were paranormal light shows, unexplained breezes, smells, raps, taps, writing on a pad by unseen hands, sudden freezing cold, water splashes, ringing bells, writing on unexposed film, crackling sounds . . .
