If this is truly the best of Hans Holzer, then I think I've read all the Holzer I need to read.

This anthology, edited by Raymond Buckland, of some of Holzer's writings on ghosts, apparitions, possessions and the like contains very little content of any merit.

Instead, what you get in these pages is a mishmash of vague assumptions and suggestions alongside surprisingly few actual ghost stories, with a touch of Holzer's own beliefs about possession thrown in at the end. Several chapters on ghosts of the American Revolution era barely even touch on the famous individuals referred to, the material on premonitions (such as the deaths of Abraham Lincoln and John F. Kennedy) is ridiculously vague and unconvincing, and information gleaned from seances (particularly one with the spirit of Elvis Presley) possesses nothing to actually make them remotely believable. The only haunted location that gets a decent treatment is the Waverley House.

Honestly, if I had picked up a manuscript of this book with no knowledge of the author and editor, I would have presumed the writer to be someone seeking to make Hans Holzer look bad.
