Bertha Mason Character Analysis

While I paced softly on, the last sound I expected to hear in so still a region, a laugh, struck my ear. It was a curious laugh; distinct, formal, mirthless. I stopped: the sound ceased, only for an instant; it began again, louder: for at first, though distinct, it was very low. It passed off in a clamorous peal that seemed to wake an echo in every lonely chamber; though it originated but in one, and I could have pointed out the door whence the accents issued.

What crime was this that lived incarnate in this sequestered mansion, and could neither be expelled nor subdued by the owner?—what mystery, that broke out now in fire and now in blood, at the deadest hours of night? What creature was it, that, masked in an ordinary woman's face and shape, uttered the voice, now of a mocking demon, and anon of a carrion-seeking bird of prey?

What it was, whether beast or human being, one could not, at first sight, tell: it grovelled, seemingly, on all fours; it snatched and growled like some strange wild animal: but it was covered with clothing, and a quantity of dark, grizzled hair, wild as a mane, hid its head and face.
