Next to Last Stand

Custer's Last Fight, copied and distributed by Anheuser-Busch at a rate of more than a million copies a year, was destroyed in a fire at the Seventh Cavalry headquarters in Fort Bliss, Texas, in 1946. Or was it ? When Charley Lee Stillwater dies of an apparent heart attack at the Veterans' Home of Wyoming, Walt Longmire is called in to try to make sense of a partial painting and a Florsheim shoebox containing one million dollars, both found in Stillwater's foot locker, sending the good sheriff on the trail of a dangerous art heist.
As he follows the money - encountering some nefarious characters along the way - Longmire strives to make sure that this investigation doesn't become his own next to last stand.
