Tom Swan and the Head of St George Part One: Castillon

Castillon: Part One of a fast-paced serialised novel set in the turbulent Europe of the fifteenth century.1450s France. A young Englishman, Tom Swan, is kneeling in the dirt, waiting to be killed by the French who have taken him captive. He's not a professional soldier. He's really a merchant and a scholar looking for remnants of Ancient Greece and Rome - temples, graves, pottery, fabulous animals, unicorn horns.
But he also has a real talent for ending up in the midst of violence when he didn't mean to. Having used his wits to escape execution, he begins a series of adventures that take him to street duels in Italy, meetings with remarkable men - from Leonardo Da Vinci to Vlad Dracula - and from the intrigues of the War of the Roses to the fall of Constantinople.
