Tony Sullivan lives in South East London with his wife and three children. His first book, _King Arthur: Man or Myth?_ was published in 2020\. Three further books followed in 2022: _The Battles of King Arthur_ investigating the famous battle list from the Historia Brittonum; _The Real Gladiator_, looking at the historical reality behind the 2000 film; and _The Roman King Arthur?: Lucius Artorius Castus_, which dismantles the Artorius-Arthur theory and places this historical Roman officer in the reigns of Severus and Caracalla.
""A simply fascinating read from start to finish... is exceptionally well written and impressively 'reader friendly' in organization and presentation. ...a very highly rated and unreservedly recommended...""-- ""Midwest Book Review""
