The novel “Psychlone” by Greg Bear was published for the first time in 1979. Larry Fowler is invited by his old friend Henry Taggart to try to make objective measurements of strange poltergeist phenomena. Fowler is skeptical but he sees really extraordinary phenomena. Some days later, Taggart and his father die in a homicide-suicide case and Fowler thinks there’s a connection with the poltergeist phenomena so he goes back to investigate.
