Sherlock will premiere its fourth season on PBS later tonight, and fans can now take a look at the set of the series in a different light.

PBS released a new time-lapse video that shows the building of the set. Check that out below.

Fans can expect some big changes in season four. The cast talked about the new baby that is a part of the show now in recent clips.

Benedict Cumberbatch spoke about the new season of Sherlock in an interview released by BBC One. He said the following:

“There are a lot of new things going on, for example there’s a baby! So parenting responsibilities have kicked in for the super sleuths! Childcare is never easy but it gets even more complicated when crime’s involved.”
