Andy Thomas is one of the UK’s best-known authors and lecturers on paranormal phenomena and cover-ups, and is author of the acclaimed books Strange, Conspiracies, The New Heretics, The Truth Agenda and Christmas among others, including several books on crop circles. He also lectures on English history and folklore and speaks extensively in Britain and around the world at many kinds of events. His books have been widely praised as the finest available overviews of their subjects.

For three and a half decades Andy has investigated many enduring mystery subjects in a refreshingly balanced way, including conspiracy beliefs, freedom issues and paranormal areas such as crop circles, UFOs and other enigmas. He also speaks passionately on mainstream history and folklore. Andy has appeared on many popular radio, podcast and TV shows including The One Show, Richard and Judy, Esther, GMTV and Sky TV’s hit series Pineapple Dance Studios, and on US shows such as Caught on Camera, with appearances on The History Channel and National Geographic Channel. He also featured in the US cinema-released documentary Crop Circles: Quest For Truth.

Andy’s latest book, Strange (2025), published by the renowned Watkins Publishing, shares and examines many of the thousands of accounts of unexplained phenomena he has compiled over the years and is the culmination of his exhaustive work in this area. His previous book, The New Heretics (2021), was a brave encouragement for understanding of those who question orthodoxy, while its predecessor Conspiracies: The Facts – The Theories – The Evidence (latest edition 2019) is seen as a crucial overview of its subjects, appearing in several translations. Andy’s earlier book on mysteries and cover-ups, The Truth Agenda (latest edition 2013), was adopted as a sociology textbook at Canada’s Vancouver Island University.

Meanwhile, Vital Signs: A Complete Guide to the Crop Circle Mystery, has been described by many as the definitive guide to the circle controversy and was nominated for Kindred Spirit magazine’s 2002 Best Book award. His book An Introduction to Crop Circleswas a bestseller in British tourist outlets.

Andy is also author of the celebrated Christmas – A Short History from Solstice to Santa (2019 – also available as a Spanish edition) and four books on Sussex history.

Andy has written for many journals and magazines, including Kindred Spirit and New Dawn, and he regularly contributes to the popular alternative journal Nexus Magazine. He has also edited and helped produce books for other people, including Geoff Stray’s influential Beyond 2012: Catastrophe or Ecstasy (2005) and Richard Smith’s A Future World Vision (2011).

One of Britain’s most prolific lecturers, Andy is renowned for his striking presentations on ‘mysteries and histories’ across the UK, and has presented in many other parts of the world, including America, Australia, Brazil, Peru, Denmark and several European countries. Andy has given thousands of lectures over the years and has addressed a huge number of people in that time.

Andy regularly addresses all kinds of groups, including established organisations such as The National Trust, U3A, the Women’s Institute, Rotary, Round Table and Probus, to name but a few. Andy speaks for audiences of all sizes, from intimate events to large conferences [Andy’s appearance at Goldsmiths, University of London, pictured.]

Andy is founder of the Changing Times truth and mysteries group in East Sussex and is also co-presenter of the celebrated Glastonbury Symposium, one of the UK’s longest-running alternative events. He was also an experienced keyboard player for many years and wrote music with his co-composer David Swingland, examples of which are available online, and played live with guitarist Phil Light. Andy is married to the well-known psychological astrologer Helen Sewell.

Andy’s perceptive and accessible views on unusual subjects have become widely respected for giving credibility to areas not generally given the coverage they truly deserve, while always leaving audiences to make their own minds up.
