|Close Encounters of the Fatal Kind|
and author Nick Redfern
This is one of the few books in my collection (now at 122) that isn't on cryptozoology. It isn't really about UFOs either - it focuses on people who saw, investigated, or knew about UFOs that died under mysterious circumstances, things like suicides that are probably actually murders, strange disappearances, death because of contact with UFOs and alien viruses, and many, many other scary things.
Redfern writes about many times when UFO researchers seemed to have died too young. Is it all coincidence? I don't think so. Believe it or not, there is even a chapter about John F. Kennedy's assassination in 1963. Guess what: Kennedy wanted to release what the government knew about UFOs to the public - and that could be why he was killed!
There are many other interesting(and sometimes pretty scary) stories in Close Encounters of the Fatal Kind. I'd give it a 5/5 and recommend it to anyone interested in UFOs, but be warned, it might just scare you into NOT being interested in UFOs!
