Blood-Stock! (A Breed Western #09). Breed, #9

Jody Taggart didn't have a friend in the world. Until the tall blond man called Breed found Taggart's horse shot dead and Taggart with a bullet in his mangled guts. Then the horse-breeder found the kind of friend he needed-the kind who dealt in death. Breed had his own code. An instinct for justice. He couldn't stand to see a horses of the quality that Taggart bred go to waste. He owed Taggart nothing but offered his help.
Dan Fogarty ran the township of Comstock and the surrounding lands-apart from Taggart's place-and that didn't sit well with the land baron. But he soon found that you just don't mess with Breed. Not if you want to stay alive. And Fogarty's hired gunmen learned that the hard way as the land suddenly took on a whole new complexion-blood red!
