It’s the holidays and characters from A Christmas Carol have crossed paths with Sherlock Holmes. In this mash-up, Tiny Tim is fully grown. On Christmas Eve, he enlists Holmes to investigate the mysterious death of Ebenezer Scrooge, who with the help of three ghosts was transformed from a stingy grump into a generous old man. Written and directed by Mark Shanahan, and back for its second holiday run, the show stars Ben Caplan as the Victorian detective. —Jensen Davis
