You climb into the small space, and pull yourself up by the rope. You
go up about 100 floors, and just as you were going to give up, you get
to a floor with light. You climb out. Suddenly, a knife is thrown from
the darkness outside of the door. It is aimed perfectly, but you duck.
It hits the rope on the dumbwaiter, and makes it fall. Now you can't
escape that way. Where do you go?
