This is a complete guide to the supernatural. Every type of ghost is covered in this handbook for the potential ghostbuster: violent, malevolent poltergeists; recording ghosts which don't react to your presence; interactive ghosts which do, and many others - as well as examples of haunted machinery and aeroplanes. The book documents the first-hand accounts of witnesses and the testimonies of expert ghosthunters who regularly set up vigils in the most notoriously haunted places. The authors, expert researchers into the paranormal, give practical advice on how and where to set up your own vigil, as well as on what to do when you actually spot your spook.
