Read it through once

This sound disturbed an old woman who was sleeping in a chair beside me. She was a hired nurse, the wife of one of the turnkeys, and her countenance expressed all those bad qualities which often characterise that class. The lines of her face were hard and rude, like that of persons accustomed to see without sympathising in sights of misery. Her tone expressed her entire indifference; she addressed me in English, and the voice struck me as one that I had heard during my sufferings.
