Digital analysis of sound recordings at the instant of his assassination in Dallas, Texas on November 22, 1963, seems to prove Lee Harvey Oswald was not the only gunman - but with so many fragments of confused evidence, who will ever prove the truth? You could! You possess the most powerful espionage tool in the world, your mind. I was approached by American agents in the early Seventies to help set up a psychic spy operation. Formed in response to reports of highly effective KGB psychics, the remote viewing (RV) program at Stanford Research Institute in California tested clairvoyants by giving them obscure map references and asking them to describe what they 'saw'. The program developed into the covert Project StarGate - though I pulled out of CIA work when it turned sinister. I was asked to stop a pig's heart using Mindpower ... I feared a human heart could be next. But years later I used RV to 'travel back in time' to Memphis, Tennesee, to April 4, 1968, to watch the killing of Martin Luther King. What I sensed there convinced me that a lone assassin was not responsible. Remote viewing is an innate talent for almost everyone, and easy to develop. Suppose you want to visit the Copacabana beach in Brazil's Rio. Sit back in a comfortable chair and breathe deeply. Let your body relax - feel the tension flow out of your muscles. Close your eyes and visualise a glowing, golden door at the front of your mind. When you step through this doorway, you will walk out onto the beach. Alert all your senses - what you 'see' may be hazy at first, so prepare to use your hearing and especially your sense of smell - the tang of warm sunshine on salt sea will make the scene vivid.

Now - set the co-ordinates for Dallas, November '63.
