I saw a room I remembered to have seen before, the day Mrs. Fairfax showed me over the house: it was hung with tapestry; but the tapestry was now looped up in one part, and there was a door apparent, which had then been concealed. This door was open; a light shown out of the room within: I heard thence a snarling, snatching sound, almost like a dog quarrelling…I walked round to the other side of the large bed, which with its drawn curtains concealed a considerable portion of the chamber. An easy-chair was near the bed-head: a man sat at it, dressed with the exception of his coat: he was still; his head leant back; his eyes were closed. Mr. Rochester held the candle over him; I recognised in his pale and seemingly lifeless face – the stranger, Mason: I saw, too, that his linen on one side, and one arm, was almost soaked in blood.

Jane Eyre, Chapter 20. The Gothic aspect of the novel comes across strongly in this passage, as Richard Mason is discovered soaked in blood and the snarling of a wild beast is heard. The dark, the candlelight, the pale and lifeless face, heighten the Gothic atmosphere of menace and threat from some mysterious force. We find out later that Mason was attacked by his sister Bertha.
