For over a century, scientists have searched for proof that man survives death. In this book, and the BBC2 television series which it accompanies, Jeffrey Iverson looks for evidence of an after-life. Enquiries into the existence of psi powers which survive death of the brain include experiments in viewing at a distance where the odds against guessing correctly are billions to one, and the story of a team of psychics, led by a parapsychologist, who saw the infamous New York Son of Sam killer.
