Inside the maids room is dark and grey.  It is much different from the rest of the Castle which has grand walls and floors and paintings from famous painters around the wall.  The maid holds many secrets in this room.  One which is a secret door that holds paintings she should not have.
Castle Maids' Room, Inside Castle

I was hired to paint a portrait of the noblewoman the king would eventually marry. It seems that the painting was too flattering and when the king lifted the veil, he was very angry. I have been imprisoned for four long years. I had a wife and six children, but they do not wait for me to return. I turn my agony into art.
Hello, worker. Are you here to help me paint? Yes.  I am waiting on timber for my next raft, and have been sent to help you paint. Great. I hope this goes better than the last time I painted for the king. What happened the last time? Let me get out of this heavy chain mail.  I'm imprisoned in the castle for four years. I painted a portrait of him and the noblewoman he would marry. He was too flattered I believe. Ah so your very good at what you do.  I should probably tell you, a few minutes ago I noticed that one of the panels on the wall was loose.  I inspected it and it looks like a hollow panel, secret door.  Oh, yes. The maid has hidden some things. I can't bring myself to report it. Me either.  I feel sorry for her.  Look at this dreadful room the king has put her in.  Can you really blame her? What about me? I can't see my kids or wife and she won't wait for my return. Maybe I can help you escape here.... for a price. I don't know how much I care about people who would leave me so quickly. But, I do want to escape.  put this on.  At midnight, meet me back here.  The maid is gone with the queen for a few days.  I can help you escape through her secret door.  I've got a raft waiting at the river for transport.
