Edgar Rice Burroughs 
The Outlaw of Torn [PDF ebook] 

The Outlaw of Torn is a historical novel by Edgar Rice Burroughs, originally published as a five-part serial in New Story Magazine from January to May 1914, and first published in book form by A. C. Mc Clurg in 1927. It was Burroughs’ second novel, his first being the science fiction work A Princess of Mars. His third was Tarzan of the Apes.
The story is set in 13th century England and concerns the fictional outlaw Norman of Torn, who purportedly harried the country during the power struggle between King Henry III and Simon de Montfort. Norman is the supposed son of the Frenchman de Vac, once the king’s fencing master, who has a grudge against his former employer and raises the boy to be a simple, brutal killing machine with a hatred of all things English. His intentions are partially subverted by a priest who befriends Norman and teaches him his letters and chivalry towards women.
Otherwise, all goes according to plan. By 17, Norman is the best swordsman in all of England; by the age of 18, he has a large bounty on his head, and by the age of 19, he leads the largest band of thieves in all of England. None can catch or best him. In his hatred for the king he even becomes involved in the civil war, which turns the tide in favor of de Montfort. In another guise, that of Roger de Conde, he becomes involved with de Montfort’s daughter Bertrade, defending her against her and her father’s enemies. She notes in him a curious resemblance to the king’s son and heir Prince Edward.
