I was congratulating myself on finishing The Redhead by the Side of the Road by Anne Tyler in two days, and then I finished Larry McMurty's The Last Kind Words Saloon in a day.
Admittedly, it's no epic-length Lonesome Dove. This is a short book, each chapter a snippet of a few pages, alternating among the cast of characters. There are some returning figures from past books, like Charles Goodnight, but the book begins and ends with Wyatt Earp and Doc Holliday, first passing the time and shooting the breeze in front of the eponymous saloon (like the crew The King of the Hill crew) and ending with the fabled shootout at the OK Corral.
Well, not quite ending, but the final chapter is more of an epilogue, with remaining (surviving) characters mourning the harsh, dusty, violent, but still glory days of the Old West.
