Larramee's Ranch, by Max Brand (epub/Kindle/pdf)
The charge was murder—and now Tom Holden had big trouble on his hands. First, he'd held off the town bully, big Crogan, and his men single-handedly. Then he announced he would marry Alexa Larrame, beautiful blue-eyed daughter of the wealthiest rancher around—even though he'd never even met her!
But now he had a lot more than just a rash promise to live up to. He was being accused of murder in a town where the strong make the laws—and enforce them with bullets!
