A strange clue in an empty room, a blood-soaked car, a priceless Old Master, a deranged bomber. With the clock ticking, the curtain rises on a battle of wits between Sherlock, John and the shadowy stranger who seems to know all the answers...[BBC Sherlock]
Could the shadowy stranger possibly be Holme's greatest enemy, Professor Moriarty? I'm thinking yes, it will be him; but as to whether or not we'll get to see Sherlock's nemesis this season, I'm not sure. I'm guessing Steven Moffat and Mark Gatiss will keep him for upcoming seasons that the BBC now really wants.
The last episode of the fantastic Steven Moffat and Mark Gatiss series Sherlock starring Benedict Cumberbatch and Martin Freeman will air this Sunday on BBC One and BBC HD at 9pm.
