King John is tired of having his taxes stolen so he decides at last to replace the Sheriff. The new Sheriff, Philip Mark, is known as 'The Butcher of Lincoln' and his Saracen sidekick Sarak is not much better. Determined to catch the Outlaws, Philip Mark formulates a ruthless plan.

Robin and the Outlaws make their way to Croxden Abbey to give away their loot to Abbot Martin - a fanatical monk and custodian of the Cross of Saint Ciricus, which is said to have healing powers. En route they come across a Lady, a victim of a robbery on her way to Croxden. Thinking she is about to die, the Lady makes a confession to Friar Tuck and reveals a strange connection between herself and Robin.

Much has been wounded in a forester's trap. His wound becomes infected and he is very ill. The Outlaws are miles away from any of their known safe villages, but happen across a kindly carter who offers to take them to his village Cromm Cruac. However, Gulnar - formerly the sooth-sayer to Owen of Clun, is not far away and has an old score to settle.
