Between 12:30pm and 1:30pm tomorrow (Friday 28 June) we'll be joined by Sherlock's Louise Brealey - Molly Hooper herself - for a live webchat about the show.
You can post your questions on the live blog as we chat to Louise but why not get ahead of the game and leave some for her here in advance? We'll pick some of the best and put them to Louise along with the other questions that come up on the day. Just post in the comments section below.
And remember to come back tomorrow at 12:30pm for the live chat with Louise.
