Describe the man who answered the door.

From the text:

He was a mean, stooping, narrow-shouldered, clay-faced creature; and his age might have been anything between fifty and seventy. His nightcap was of flannel, and so was the nightgown that he wore, instead of coat and waistcoat, over his ragged shirt. He was long unshaved; but what most distressed and even daunted me, he would neither take his eyes away from me nor look me fairly in the face. What he was, whether by trade or birth, was more than I could fathom; but he seemed most like an old, unprofitable serving-man, who should have been left in charge of that big house upon board wages.
