"But he heard me ask for your husband's house,—did he not, Miss Vila? And why on earth you should make such a mystery of it all I can't see."

"Do draw the shade, Julia. It makes me nervous. I feel as if he were looking in now."

"Nonsense, Lillie! he's a gentleman."

"But why do you make such a mystery of it all?" persisted the young man.

"There is no mystery," said Miss Vila stiffly. And, gathering up her work, she went up-stairs.

"It's only play mystery, Henry," said his cousin, when they were alone. "You see, Lillie Vila has been coming out in the horse-car with him every night for a long time; and she has seen him watching her. Of course she has seen him, but he has not seen that she has seen him. Men are so stupid. And she knows that he has tried in vain to find out who she is. He saw her once go into the library. She was dreadfully afraid he would come in and see her working behind the screen; but he evidently fancied she went in to get a book. Then he is always managing to stand or sit near her, and he peeks at her book when she is reading. He is just dying, I know, to find out who she is."

THE REAL MYSTERY.

Mr. Austin Buckingham found on his table, when he returned from his walk with Henry Wilding, a scrap of paper. It had nothing on it but the words "The Mystery." This was the heading which he had made for his story. He had been interrupted by his caller just as he had written the words. He had not the remotest notion when he set them down what the mystery was which he meant to reveal. The title now seemed like a prophecy to him. Instead, however, of jotting down an outline of his story, he took out his note-book and wrote busily:

"I wish I knew just what I saw this evening. I had walked out with Henry Wilding, who called, and who was going, he said, to his cousin's. Now, I will not conceal from my faithful journal that I was moved by a desire to know just who his cousin was and where he or she lived; for by a most fortunate chance I have found out that my maiden without a name lives, or probably lives, at a Mr. Martindale's, on this street. I tried to draw Wilding out without betraying my own interest, but he was very obtuse, and even seemed to be ashamed of his cousin. At any rate, he parried my questions, and of course I could not push my curiosity. However, I got the better of him, and walked out with him when he left. As luck would have it again, the shades were drawn at the house where he stopped, and the bright light within made the scene perfectly distinct. I talked on the door-step about I know not what, half hoping that Wilding would invite me in, but really absorbed in watching two ladies who sat by a table. One was my fair unknown, the other a lady whom I have occasionally seen, and whom I take to be Wilding's cousin,—though this is all guess-work. Whether she is or not, she is evidently a very unpleasant sort of body, for, whatever she said, the other was plainly exceedingly vexed and mortified. She covered her face with her hands. At one time she made a movement as if to leave. She looked earnest and troubled. I could vow she was about to burst into tears. Her face was very expressive. No one who shows such sudden changes can help being a person of rare sensibility. I am almost out of conceit of making her the heroine of my story, though, to be sure, I am not likely to interfere with her personal rights, so long as I do not know either her name or her history.
