The second discovery came in the middle of the night, when she was 
awakened by a metallic clanking sound coming through the tiny window on the air 
shaft. Reaching out with one hand, she felt the end of a chain dangling there. 
She pulled on it, and after initial resistance, it came freely. In short order 
she was able to pull many yards of chain into her cell and pile it up on the 
floor.
