Robin Hood and the Heretic Prince

'Your Excellency,' said the knight, 'there may also be Christians in there. How can we tell which is a heretic, and which a good Catholic?' 'Kill them all,' said the papal legate. 'God will know his own!' AD 1209: When a robbery in Sherwood goes wrong, Robin Hood, Sir Alan Dale and a handful of their outlaw friends are forced to flee their homes to escape the wrath of a vengeful King John and his iron-hearted Sheriff of Nottinghamshire. After travelling to the Languedoc, a land of good food, fine wine, elegant love poetry and religious tolerance, the Sherwood men find themselves caught up in a blood-soaked crusade launched by Pope Innocent III. Robin Hood and his band become mercenaries in the employ of the Count of Toulouse, tasked with protecting his people, whom the Pope has condemned to death as Cathar heretics. At the Castle of Béziers, besieged by an army of fanatical Catholic crusaders, the Sherwood heroes vow to hold its walls against these northern French knights until the Heavens fall. But one member of their company has other ideas . . .
