“Ah,” murmured he, scarcely knowing the meaning of the words he uttered, “I had every confidence in you, and you have forgotten me.”

“You do not believe the words you have just spoken,” returned the Duchess haughtily; “but,” she added in softer accents, “what could I do?  I may have been weak in obeying my father, but for all that I have never forgotten the past.”

Madame de Mussidan, who had stationed herself behind the closed door, caught every word, and a gleam of diabolical triumph flashed from her eyes.  She felt sure that an interview which began in this manner would be certain to be repeated, and she was not in error.  She soon saw that by some tacit understanding the Duchess and George contrived to meet constantly at her house, and this she carefully abstained from noticing.  Things were working exactly as she desired and she waited, for she could well afford to do so, knowing that the impending crash could not long be delayed.

With a sly look, the man drew from his pocket a letter.

“This is for you,” muttered he.

“All right; give it to me, then.”

“I was told to give it to you only in private.”

“Never mind that; hand it over.”

“Well, if I must, I must.”

Norbert’s sole thought was that this letter must have come from Diana, and throwing the man a coin, hurried to a spot where it was light enough to read the missive.  He did not, however, recognize Diana’s firm, bold hand on the envelope.

“Who the devil can this be from?” thought Norbert, as he tore open the outer covering.  The paper within was soiled and greasy, and the handwriting was of the vilest description, it was full of bad spelling, and ran thus:—­

“Sir,—­
