When Sherlock Holmes creator Sir Arthur Conan Doyle wanted to end his literary series about the great detective, he had his hero plummet to his death while fighting an enemy over the Reichenbach Falls. It’s fitting, then, that Holmes (Jonny Lee Miller) ends his TV adventures in this contemporary reboot fighting a tech billionaire named Otto Reichenbach (James Frain) in the series finale, "Their Last Bow." The teleplay is by executive producer Robert Doherty, who has been with "Elementary" since its 2012 premiere. Lucy Liu also stars.
