Season 4 of Sherlock aired in January. Passport members can stream it here.

The end approaches. On Sunday, January 15 at 6:00 pm, the finale of Sherlock season 4 airs. Show co-creators Steven Moffat and Mark Gatiss have hinted that this may be the last season, at least for a long while, and there's a lot that needs to be wrapped up. Did Sherlock's newly-revealed sister Euros just shoot John? Is she in league with Moriarty? What is Moriarty's plan, and is he even still alive? Has John reconciled himself to Mary's death? Who is Sherrinford? What is this huge explosion in the trailer?

Martin Freeman as John Watson.

So the finale should be a shocker. "The Final Problem" awaits.
