"'Finest,'" Will repeats with a sneer, as he walks up the stairs. Upon reaching the top, his features soften, and he smiles at Malcolm. "Well. One of them produced you, so I suppose they're not all bad."

But Malcolm's answer did highlight the strangeness of the assistant being here. It's not really a live-in position, is it? More Miss Windsor's house, so unless the assistant was acting as a maid to Windsor-- he realizes an assumption he was already making. "She wouldn't have a male assistant living here with her. Too unbecoming. So-"

He sweeps past the living quarters for Windsor to find the access to the attic. That's the room he needs to see.
