Sheriff Walt Longmire is reading A Christmas Carol in his office on December 24th when he's interrupted by a young woman with a hairline scar across her forehead and more than a few questions about Walt's predecessor. The mystery woman seems to know him and claims to have something she must return to Lucian Connally. On his own for the holidays, Walt is at loose ends -- and despite the woman's reticence to reveal her identity, he agrees to help her. (Bestseller).
