A Brief Guide to Ghost Hunting reviewed by Dr Tom Ruffles:

In an age when ghost hunting groups proliferate but their standards are often woefully inadequate, solid and reliable information on how to carry out an investigation properly is essential.  In response to that need, Leo Ruickbie has written a useful guide which will assist investigators to conduct meaningful research.  Subtitled ‘How to Identify and Investigate Spirits, Poltergeists, Hauntings and Other Paranormal Activity’, its progression is logical, taking the reader through the process of evaluation, equipment, investigation methods, analysis, and interpretation of results.  In addition he discusses more general issues of psychical research, drawing heavily on the files of the Society for Psychical Research (SPR) and the Ghost Club.  Supplementing such historical material he conducted two surveys, the ‘Ghost Hunting Survey’, interviewing investigators, and a ‘Preliminary Survey of Hauntings’, the latter examining nearly a thousand reports from across the UK.
