The Edge of the Unknown

€ 1,26

A small, solid iron tank was filled with water. A man was placed inside, water completely covering him. Over this an iron lid with three hasps & staples was securely locked. The body was submerged & a clock began ticking off the seconds. In less than a minute & a half, the entombed man was standing calmly outside the tank, still dripping the locks had not been touched, the lid was still secure. Once again, the great Harry Houdini had confounded scientists & his audience by escaping sure death! How was it possible to survive this? His friend, Arthur Conan Doyle, thought the answer might lie in spiritualism. The Edge of the Unknown presents the evidence.
