People in "the know" have suspected for a long time that Sherlock will return to UK screens on New Year's Day 2014.
Well connected sources this week started announcing the speculation as fact.
Which slightly goes against what Executive Producer Sue Vertue said back in August:
Now, a US airdate of January 19 has been confirmed by PBS.
Sherlock will air in the UK before it airs in America. However we won't be in a position to announce the date until later in the year
