This take on Sir Arthur Conan Doyle's classic character has Sherlock Holmes fleeing London for present-day Manhattan after a stint in rehab. He arrives to find that his father has assigned a sober companion to live with him -- Dr. Joan Watson, a former surgeon who gave up medicine three years earlier after she lost a patient. Her life now centers around helping addicts stay clean. However, Holmes has his own plan for keeping on the straight and narrow, throwing himself into his work as a police consultant in New York City. The two find that they make a good team and are soon cracking some of the NYPD's most-difficult cases.
