How Does Elementary End?
How Elementary Wraps Things Up For Holmes, Watson, and the Rest of the Crew
2
In the three years since Sherlock's disappearance and the defeat of Reichenbach, Joan has adopted an adorable son, Arthur, is still working with the NYPD, and has just written a best-selling memoir about her work with Sherlock. She signals him back when an associate of Moriarty's leaves a package behind for her, but hides the fact that she's been diagnosed with cancer. Sherlock finds out anyway and decides to stay with her and Arthur. A year later, her chemo has been successful, and the pair return to consult with the NYPD.
