You scramble onto the patio roof, making sure that you don't fall off or knock off any tiles. Looking through the open window you see the room is one of the bathrooms. You numbered it room 17 for ease. There are 75 rooms in total and the diamonds are in room 73.
You slide your slender body through the grab the nearby sink for support. Finally in, you sit on the bath and observe your surroudings, or rather listen for footsteps. No-one seems to be on this floor but you know the bedroom is just upstairs.
You open the door and tiptoe until you find the staircase. You are about to climb up it when a light upstairs flickers followed by footsteps...What do you do?
