Peter Falk plays Lt. Columbo, a detective without a first name, in the series created by Richard Levinson and William Link. The long-running show inverted the classic detective formula: The TV audience already knew whodunit when Columbo arrived on the scene of the crime. The enjoyment for viewers was in seeing how Columbo doggedly pieced the clues together. As he said in one episode, "I have this bug about tying up loose ends."
