Cassidy could fan a gun like a Bill the Kid... Six rounds in three seconds was his slowest time. No one in the state of Texas could beat him. Until he met Slim Travennes, head of the Sandy Creek Vigilante Committee. Slim was snake-fast. No man could go up against him and live. No man. Hoppy could stand or die. He had no other choice. None at all. But alongside Hopalong Cassidy and his friends have to investigate a series of cattle thefts at the Bar 20 ranch and Mulford’s storytelling will keep readers on the edge of their seats as they follow Hopalong Cassidy's journey to uncover the rustlers' identities.
