Over the Border 

‚Over the Border‘ is a fascinating tale about hypnosis and mesmerism. The narrator lost much of his memory for many years after leaving his former life as a sailor. One night he visits a theatre where a hypnotist is performing. On his way home on the tram, he hears two doctors discussing a case at the hospital – a man with amnesia. One doctor recommends hypnosis as therapy to try to access the lost memories. (Amazon)
