Case files from the 1960's of Professor Hans Holzer, famous ghost hunter. Some are just stories told to him, some he investigated at the location, often bringing a psychic (medium) who became the ghost and spoke in a trance. The author's writing style was kind of stiff, and I thought the book was boring.
It didn't offer much supporting information, but still put a chill down my spine.
These are a series of real ghost hauntings authenticated by the author. The hauntings range from NH, VA, CA, LA, MN, etc. In all, 25 true, witnessed accounts are reported by Dr. Holzer.
As a seasoned paranormal investigator I have to say Hans Holzer is just amazing. This book however really did not keep my attention as well as some of his others.
