A suited Santa apparently fell to his death from the sky, but actually was shot first. He's ultimately identified as former business shark Edmund, who chose 6 years ago to become one of Dave Dunne's professionally trained Santas and ended his marriage. He also helped poor residents fight their eviction by a big company. It turns out he used illegal means, but was far from the only crook in the story, not even counting his murderer. Meanwhile Castle's family and fellow detectives wrestle with holiday planning.
