Book excerpt: In this first of four classic frontier novels, Louis L'Amour adds his own special brand to the life and adventures of one of America's favorite fictional cowboys, Hopalong Cassidy. In The Rustlers of West Fork, the quick-thinking, fast-shooting cowpuncher heads west to deliver a fortune in bank notes to his old friend, Dick Jordan. When he arrives at the Circle J, he discovers that the rancher and his daughter, Pam, are being held prisoner by a desperate band of outlaws led by the ruthless Avery Sparr and his partner Arnold Soper. Even if Hopalong Cassidy can free Jordan and Pam, he will have to lead them across rough and untamed Apache country, stalked by the outlaws who have vowed to gun him down. But Hopalong is no stranger to trouble, and before his guns or his temper cool, he's determines to round up Sparr and his gang and bring the outlaws to justice ... dead or alive! This classic tale of pursuit and survival is vintage L'Amour and adds new life and luster to the legend of Hopalong Cassidy.
