Acclaimed historian and TV broadcaster Dan Jones returns to the county town to talk about his latest book, Crusaders.

The Crusades were a sequence of religious wars fought from the late eleventh century to the late medieval period in which armies from European Christian states tried to wrest the Holy Land from Islamic rule.Crusaders tells a tale soaked in Islamic, Christian and Jewish blood and charts the stories of not just popes and kings but gives voice to other sources usually pushed to the margins of history.
