The longer this mystery ages in my mind the more I suspect Greenfield of being a grand yarn spinner. In an unrelated podcast I heard Greenfield tell a story how he and a friend were drinking one night and called in a ufo hoax to a police station or something like that. Well next day or following days there were reported ufo sightings in that area like they described in the hoax . I think that sums up Hellier. A slow burn yarn spun by Greenfield to drum up intrested in his books. BUT along the way some pretty unexplainable phenomena occours. Is it real? Yes. Is it fake? Yes. Do you have to willfully play along to witness the strange? Likely. If i had to take a wild guess we are dealing with tricksters both mundane and cosmic.
