The Man from Bar-20 is the seventh in the Hopalong Cassidy series. When Hopalong Cassidy's friend, Johnny Nelson, left Bar-20 searching for even greater adventure, and joined the CL Ranch, he found more than he bargained for. He found a hidden valley between Twin Buttes with over 200 of CL cattle rebranded QE. He found a gang of rustlers out to steal the rest of CL's beef. He found the country's fastest gun-fighter looking to cut him down. What he should have found was a fast way out of that valley. But Hoppy never told him how to turn tail and run (Goodreads).
