A dark mysterious stranger riding across the wilderness of Bushey Heath late at night stumbles upon two bodies in the road. One of them is the young highwayman Ned Carey known as "The Ghostrider" for his ability to elude his pursuers by apparently vanishing into the hillside. The stranger takes the body to town where it is collected by Michael and Katie, the highwayman's younger brother and sister. Who is this mysterious man and why is he so kind to them? What is the connection between their much-admired Schoolmaster and the dreaded 'Resurrection Men'? How does the Ghostrider return from the dead? Is he a ghost after all?
