You may already have seen this above clip of Montague Keen dying on camera at a public meeting. Its a good watch. Keep the details in mind.
Then watch his wife Veronica do a 30 minute interview, where she describes his death as quite abnormal attested to by doctors, and a tape is played of the deceased Montague's voice coming thru a medium. More riveting than that, is what she reveals in the last 10 mins of the show. What her husband has done with her since he died. Hope you are wearing a seatbelt.
