"you must confine yourself to your room, on pretence of a headache, when your stepfather comes back. then when you hear him retire for the night, you must open the shutters of your window, undo the hasp, put your lamp there as a signal to us, and then withdraw quietly with everything which you are likely to want into the room which you used to occupy. i have no doubt that, in spite of the repairs, you could manage there for one night."
