O. Henry 
Heart of the West [PDF ebook] 

This is a fantastic collection of western-themed stories, many feature the man's signature surprise endings. There are tales of cowpunchers, desperados and ranchers in love. Most explore happy times, though death and sorrow do pay an infrequent visit. More than once the folly of male/female relationships is explored with predictably humorous results.
