Who art thou?
Whence comest thou, Sir Knight of Nubia?
Bearest thou upon thy person some written token, or, as you would say in your common parlance, what's your business ?" "Oh, I see, sah.

Yes, sah, I done got a lettah from Mr.Theophilus Moncrieffe.

That's the owner of this house, and I belong to him.
I'se Caesar Moncrieffe.

Here's the lettah, sah." He handed a folded paper to Harry, who opened and read it.

It was addressed to the chief of whatever officers might be occupying his house, and it ran thus, somewhat in the old-fashioned way: SIRS AND GENTLEMEN: The bearer of this is Caesar Moncrieffe.
