Watson is happily married and hasn't spoken to Sherlock in months and hasn't been on a mystery in nearly a year. The craziest his life gets now is an abnormal patient or some sensational news story. That's all about to change when the distraught wife of a friend comes to his house late one Thursday night, leading to a late night trip to an opium den and a shocking discovery.
