What is the CBS show "Elementary" about?

The CBS show "Elementary" provides a modern adaptation of the classic character of Sherlock Holmes, set in New York City rather than London. The two main characters are Sherlock Holmes, played by Johnny Lee Miller, and Joan Watson, played by Lucy Liu.

In "Elementary," Sherlock Holmes, a recovering addict, leaves London behind for New York City. As with Sir Arthur Conan Doyle's original character, Sherlock Holmes is a detective using his masterful deductive abilities to help the New York Police Department solve crimes throughout the city with Joan Watson by his side. Initially, Watson plays the part of the strictly professional "sober companion," but the two ultimately develop a strong friendship.
