After their recent defeat, the hamlets and villages of Derbyshire are no longer ringing with the wild shouts of Bonny Prince Charlie's Highland Brigade; instead troops loyal to King George are looking for those accused of high treason and are offering a reward of twenty guineas for the death of any traitor or rebel. Philip Gascoyne is in hiding, in fear for his life after being wrongly accused by Sir Humphrey Challoner of being a traitor to the King. He has been given shelter and a cover by honest John Stitch, the local blacksmith. John hires the notorious Beau Brocade, a masked highway man who roams the moors holding up coaches so he can steal from the rich and give to the poor, to connect Philip with his family and arrange his return to London.
