You mentioned "The Haunted Mesa". I think that is the only LL book I was not crazy about. And, you've addressed some of the problems that LL faced with it. But, he hit a couple of homeruns with "The Walking Drum" and "Last of the Breed". I think the bottom line was that he was really a master of the action story. But I think I can say that we, his fans, are truly grateful that he stayed with and wrote so many outstanding novels and short stories about the American West.
