But is she so diabolical this time around? The episode description for “The Diabolical Kind” says that Holmes and Watson’s one-time adversary is “brought in as a consultant on a kidnapping case.” The cheat tweet reads, “Moriarty is back! And she’s working w/ Holmes & Watson?!”
Oh, dear. Can she be trusted? Her appearance last season certainly threw Sherlock for a loop — and we definitely don’t like the looks of the giant picture of Joan Watson that Moriarty appears to have painted. That’s … weird.
Check out the preview video below and get excited for Moriarty’s return, Thursday, Jan. 2 at 10 p.m. ET/PT on “Sherlock” on CBS.
