P rincess Nell could see that the room was about two by three paces, with a 
stone bench on one wall to serve as a bed, and a hole in the floor for a 
toilet. A tiny barred window in the back wall led to an air shaft. Evidently 
this was quite deep and narrow, and
Nell was close to the very bottom, because no light came through it. The 
soldier walked out of the cell and pulled the door shut behind him; as he did, 
she saw that the lock was extraordinarily large, about the size of an iron 
breadbox mounted to the door, full of clockwork and with a large crank dangling 
from its center.
