Perhaps he was conscious that he might have made a more positive reply. He certainly took refuge in another subject—more agreeable to himself.

"My dear, you have expressed the wish to relieve my anxieties," he said; "and you can help me, I think, in that way. I have a letter to write—of some importance, Iris, to your interests as well as to mine—which must go to Ireland by to-day's post. You shall read it, and say if you approve of what I have done. Don't let me be disturbed. This letter, I can tell you, will make a hard demand on my poor brains—I must go and write in my own room."

Left alone with the thoughts that now crowded on her mind, Iris found her attention claimed once more by passing events. Fanny Mere arrived, to report herself on her return from Paris.

She had so managed her departure from Passy as to precede Lord Harry and Mr. Vimpany, and to watch for their arrival in Paris by a later train. They had driven from the railway to the newspaper office—-with the maid in attendance on them in another cab. When they separated, the doctor proceeded on foot to the Luxembourg Gardens. Wearing a plain black dress, and protected from close observation by her veil, Fanny followed him, cautiously keeping at a sufficient distance, now on one side of the street and now on the other. When my lord joined his friend, she just held them in view, and no more, as they walked up and down in the barest and loneliest part of the Gardens that they could find. Their talk having come to an end, they parted. Her master was the first who came out into the street; walking at a great rate, and looking most desperately upset. Mr. Vimpany next appeared, sauntering along with his hands in his pockets, grinning as if his own villainous thoughts were thoroughly amusing him. Fanny was now more careful than ever not to lose sight of the doctor. The course which he pursued led them to the famous hospital called the Hotel Dieu.

At the entrance she saw him take a letter out of his pocket, and give it to the porter. Soon afterwards, a person appeared who greeted him politely, and conducted him into the building. For more than an hour, Fanny waited to see Mr. Vimpany come out again, and waited in vain. What could he possibly want in a French hospital? And why had he remained in that foreign institution for so long a time? Baffled by these mysteries, and weary after much walking, Fanny made the best of her way home, and consulted her mistress.

Even if Iris had been capable of enlightening her, the opportunity was wanting. Lord Harry entered the room, with the letter which he had just written, open in his hand, As a matter of course, the maid retired.

DIRE NECESSITY

THE Irish lord had a word to say to his wife, before he submitted to her the letter which he had just written.
