内容简介：Eighty years later, Charles's grandson Bob Lee Swagger uncovers a strongbox containing an array of memorabilia dating back to 1934--a federal lawman's badge, a .45 automatic preserved in cosmoline, a mysterious gun part, and a cryptic diagram--all belonging to Charles Swagger. Bob becomes determined to find out what happened to his grandfather-- and why his own father never spoke of Charles. But as he investigates, Bob learns that someone is following him--and shares his obsession.
