New 'Sherlock' images peek at Sherlock and John's family lives

We have to wait a bit longer to see what adventures await Sherlock Holmes and Dr. John Watson, played by Benedict Cumberbatch and Martin Freeman, in the new season of "Sherlock." But that doesn't mean we can't try to find hints in the new images from the show released on Wednesday.

This photo shows Sherlock, Dr. Watson and Mary Morstan (Amanda Abbington) and gives a first look at baby Watson.

The new season starts January 1 on PBS and BBC On.

It wouldn't be a proper "Sherlock" season without Holmes' beloved landlady Mrs. Hudson (Una Stubbs) watching out for the troubled detective.

Dr. John Watson looks a bit older and wiser in this image. Here's hoping Sherlock cuts him some slack this season.

We were treated to an image of Sherlock Holmes teaming up with a new canine companion in July. Here's a behind-the-scenes photo of Sherlock with the same Bloodhound, along with John's wife, Mary Morstan.

If previous "Sherlock" seasons have taught us fans anything, it's never underestimate brothers Sherlock and Mycroft, played by Mark Gatiss. Both are clever, and eager to catch equally-cunning criminals.

In May, it was announced that actor Toby Jones would play the mysterious villain Culverton Smith in episode two. Here he is, clearly up to something.

Mycroft Holmes has always been a powerful man with many secrets. What can you deduce from the sign behind him?
