We speak with Craig Johnson, author of "The Cold Dish: A Walt Longmire Mystery" and the subsequent books in the best-selling series. The books inspired the new program "Longmire," a highly-rated series on A&E. The character of Walt Longmire is a sheriff in rural Wyoming. The books offer up an entertaining and authentic taste of life in the modern American West, where Johnson was born and still lives. (The TV series is actually filmed in the Santa Fe and Las Vegas, New Mexico areas)
