This book is a field guide for the prospective paranormal investigator. It provides information on how to form a group for the investigation of the paranormal, how to research haunted areas and much more. The advice is very practical and the author obviously has years of experience in this field. He provides details on the types of entities likely to be encountered, like ghosts, spirits or dangerous spirit creatures that are best left to an experienced exorcist. I found the sections on how to capture paranormal phenomena on film and how to record disembodied voices and sounds on tape particularly interesting, as these are easy to do with equipment that most people already have. What's more, it can be done anywhere as all walls and buildings contain some residue of recorded voices. Plenty of sources for material are provided, as well as contact details of organisations devoted to studying these phenomena. The book contains photographs, an appendix, a glossary, bibliography and index. It is a very thorough handbook for those who wish to pursue this rather unusual hobby.
