sentences:  At the climax of the story, Mordrin is shot by the mortally wounded Owen inside the Knights' chapel at the headquarters, rather than in the surrounding forest.These differences and other details – such as that the Knights wear black but otherwise conventional battledress – suggest that the book was written before production and that the television script was therefore expanded to fit the desired length.The novel also contains much additional detail about the world of 2020 and the Civil War, such as Ireland as a whole having become an American state, and the source of much of the rebels' supplies, despite an official arms embargo.
