Dennis's first book was The Missing Years of Jesus, an acclaimed study of the notion suggested in William Blake's poem 'Jerusalem' that Christ once visited Britain. He followed this with A Tale of Sound & Fury, an autobiographical account of two turbulent decades spent as a singer, poet, performer, Hell Fire Club member and knight touring Britain, Europe and Scandinavia in the 1980s and 1990s. He is now working on the first-ever definitive study of a connection between the ancient British Druids and Stonehenge. A former archaeologist, he is a prolific writer on ancient British mysteries, as well as a writer of verse, lyrics and commentaries. He lives with his family and black dog in Devon, in a rural paradise surrounded by Britain's demonised wildlife.
