Continued in George R.R. Martin's The Hedge Knight #4 published by Devil's Due.
Night falls over the life of one noble knight and brings the dawn of his squire's knighthood. Dubbing himself 'Ser Duncan the Tall', 'The Hedge Knight' sets forth to the tourney at Ashford Meadow in search of fame and glory and the honor of upholding his oath as a knight of the Seven Kingdoms. Unfortunately for him, the world isn't ready for a knight who keeps his oaths, and his chivalrous methods could be the very cause of his demise.
The Hedge Knight was written as short fiction (novella), by SFF writer George R. R. Martin, and originally published in the 1998 “Legends” anthology. It was soon followed by its later half, “The Sworn Sword”, originally published in the 2003 “Legends II” anthology. Both anthologies were edited by the esteemed SFF writer and editor Robert Silverberg.
References to the tale of Ser Duncan can be found in Martin’s epic four-book “Song of Fire and Ice” series.
The 2001 blockbuster movie, “A Knight’s Tale”, starring Heath Ledger, Rufus Sewell and Shannyn Sossamon is loosely based upon the The Hedge Knight and The Sworn Sword.
