British author and former director of investigations with the British UFO Research Association (BUFORA), serving in that role from 1982 through to 1994.
Randles specializes in writing books on UFOs and paranormal phenomena. To date 50 of these have been published, ranging from her first UFOs: A British Viewpoint (1979) to Breaking the Time Barrier: The race to build the first time machine (2005). Subjects covered include crop circles, ESP, life after death, time anomalies and spontaneous human combustion.
This book intends to be a compendium of all the information gathered on the phenomena until that period focusing on the British cases, as the UFO community was too focused on the American ones. This book does a very good job at it, trying to present a skeptical approach to the subject matter, to me it today is quite obsolete but at the time it was really a cutting-edge work. I highly recommend it.
