Mark Devlin & Andy Thomas at The Attic in Southampton - Saturday 20th June 2026

Andy Thomas, who's the co-founder and presenter of the Glastonbury Symposium

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, The New Heretics, The Truth Agenda, Conspiracies and Christmas, among other titles.

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 Circles was 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. See Books for more details on Andy’s writings.

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 books for other people, including Geoff Stray’s influential Beyond 2012: Catastrophe or Ecstasy (2005) and Richard Smith’s A Future World Vision (2011).
