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,—

“I hardly dare tell you the truth, and yet my conscience will give me no relief until I do so. I can no longer bear to see a gentleman such as you are deceived by a woman who has no heart or honorable feeling. Your wife is unfaithful to you, and will soon make you a laughing stock to all. You may trust to this being true, for I am a respectable woman, and you can easily find out if I am lying to you. Hide yourself this evening, so that you may command a view of the side-door in the wall of your garden, and between half-past ten and eleven you will see your wife’s lover enter. It is a long time since he has been furnished with a key. The hour for the meeting has been judiciously fixed, for all the servants will be out; but I implore you not to be violent, for I would not do your wife any harm, but I feel that you ought to be warned.
