Jess asked you to get the necklace Clara keeps in her briefcase; Harper will provide a little distraction so you can get to the briefcase.
Clara is in the parlor as always -- but before you go there, let's think this through. You want her to leave the room while you enter it --
-- and you don't want her to know you're there, so she can't see you go in. That means you can't use the same door she uses.
How do I get Clara to leave?
Once the coast is clear, enter the room, then turn around. The briefcase is under the table by the window.
You now have something less than 5 minutes to figure out how to open the briefcase, using the piece of paper Jess just gave you. After that, Clara returns, and it's game over.
How do I solve the briefcase clues?
