Read it through once

When I was about six years old there came to us one evening a carriage-and-four from the castle, bringing a very curious stranger—an old woman of a common appearance, who had been taken suddenly ill at the post-house. She was attended by a lady of the neighbourhood, who, on exchanging a few words with my mother, left the poor woman in our care. We had but little thought of the event till night came, and with it a strange agitation in the house.
