I do not even tell you that you lie.

What doth one expect of a gutter-dog but that it should void the garbage it hath devoured?
But I do ask you, Marshal de Retz, as a brave soldier and the representative of an honourable King, what you have done with the Lady Sybilla ?" The Marshal de Retz smiled--a smile so chill, cruel, hard, that the very soldiers on guard, seeing it, longed to slay him on the spot.
"May I, in return, ask my Lord Earl of Douglas and Duke of Touraine what is that to him ?" he said, with sneering emphasis upon the titles.
"It matters to me," replied William Douglas, boldly, "more than life, and almost as much as honour.

The Lady Sybilla did me the grace to tell me that she loved me.

And I in turn am bound to her in life and death." The Chancellor and the tutor broke into laughter, but the marshal continued to smile his terrible smile of determinate evil.
"Listen," he said at last, "hear this, my Lord of Touraine; ever since we came to this kingdom, and, indeed, long before we left the realm of France, the Lady Sybilla intended nothing else than your deception and destruction.

Poor dupe, do you not yet understand?
She it was that cozened you with fair words.
