“To the library,” she said easily, and yet with a sudden realization that all was not right with her father. His face was too heavy and gray. He looked tired and gloomy.

“Come up to my office a minute,” he said. “I want to see you before you go.”

Aileen heard this with a strange feeling of curiosity and wonder. It was not customary for her father to want to see her in his office just when she was going out; and his manner indicated, in this instance, that the exceptional procedure portended a strange revelation of some kind. Aileen, like every other person who offends against a rigid convention of the time, was conscious of and sensitive to the possible disastrous results which would follow exposure. She had often thought about what her family would think if they knew what she was doing; she had never been able to satisfy herself in her mind as to what they would do. Her father was a very vigorous man. But she had never known him to be cruel or cold in his attitude toward her or any other member of the family, and especially not toward her. Always he seemed too fond of her to be completely alienated by anything that might happen; yet she could not be sure.

Butler led the way, planting his big feet solemnly on the steps as he went up. Aileen followed with a single glance at herself in the tall pier-mirror which stood in the hall, realizing at once how charming she looked and how uncertain she was feeling about what was to follow. What could her father want? It made the color leave her cheeks for the moment, as she thought what he might want.

Butler strolled into his stuffy room and sat down in the big leather chair, disproportioned to everything else in the chamber, but which, nevertheless, accompanied his desk. Before him, against the light, was the visitor’s chair, in which he liked to have those sit whose faces he was anxious to study. When Aileen entered he motioned her to it, which was also ominous to her, and said, “Sit down there.”

She took the seat, not knowing what to make of his procedure. On the instant her promise to Cowperwood to deny everything, whatever happened, came back to her. If her father was about to attack her on that score, he would get no satisfaction, she thought. She owed it to Frank. Her pretty face strengthened and hardened on the instant. Her small, white teeth set themselves in two even rows; and her father saw quite plainly that she was consciously bracing herself for an attack of some kind. He feared by this that she was guilty, and he was all the more distressed, ashamed, outraged, made wholly unhappy. He fumbled in the left-hand pocket of his coat and drew forth from among the various papers the fatal communication so cheap in its physical texture. His big fingers fumbled almost tremulously as he fished the letter-sheet out of the small envelope and unfolded it without saying a word. Aileen watched his face and his hands, wondering what it could be that he had here. He handed the paper over, small in his big fist, and said, “Read that.”

Aileen took it, and for a second was relieved to be able to lower her eyes to the paper. Her relief vanished in a second, when she realized how in a moment she would have to raise them again and look him in the face.

DEAR SIR—This is to warn you that your daughter Aileen is running around with a man that she shouldn’t, Frank A. Cowperwood, the banker. If you don’t believe it, watch the house at 931 North Tenth Street. Then you can see for yourself.

In spite of herself the color fled from her cheeks instantly, only to come back in a hot, defiant wave.

“Why, what a lie!” she said, lifting her eyes to her father’s. “To think that any one should write such a thing of me! How dare they! I think it’s a shame!”
