One of his books (just going from memory) is "Missing Time". He wrote a few others over the years. He was killed a few years ago in London while attending a UFO . . . shit, I can't think of the word, it's not convention . . . crap, my mind is not cooperating . . . summit is the right word (I think). :P A couple of others are: "Abduction: Human Encounters with Aliens" and "Passport to the Cosmos: Human Transformation and Alien Encounters".
Not that I've been reading this kind of thing for years or anything. *hides behind rocks*
