The first impulse of Mrs. Hibberdell was to call to her. Her second thought was to let the ruse seem successful. She was convinced that Eugene was in his room, and a few moments later a monitory cough on his part--coughed for a purpose--convinced her. "Are you in the bath, Carlotta?" she called quietly, after looking into Carlotta's room. "Yes," came the reply, easily enough now. "Did your machine break down?" A few remarks were exchanged through the door and then Mrs. Hibberdell went to her room. She thought over the situation steadily for it greatly irritated her. It was not the same as the discovered irregularity of a trusted and virtuous daughter. Carlotta had not been led astray. She was a grown woman, married, experienced. In every way she knew as much about life as her mother--in some respects more. The difference between them was in ethical standards and the policy that aligns itself with common sense, decency, self preservation, as against its opposite. Carlotta had so much to look out for. Her future was in her own hands. Besides, Eugene's future, his wife's rights and interests, her mother's home, her mother's standards, were things which she ought to respect--ought to want to respect. To find her lying as she had been this long time, pretending indifference, pretending absence, and no doubt associating with Eugene all the while, was disgusting. She was very angry, not so much at Eugene, though her respect for him was greatly lowered, artist though he was, as at Carlotta. She ought to do better. She ought to be ashamed not to guard herself against a man like Eugene, instead of luring him on. It was Carlotta's fault, and she determined to reproach her bitterly and to break up this wretched alliance at once. There was an intense and bitter quarrel the next morning, for Mrs. Hibberdell decided to hold her peace until Eugene and Davis should be out of the house. She wanted to have this out with Carlotta alone, and the clash came shortly after breakfast when both the others had left. Carlotta had already warned Eugene that something might happen on account of this, but under no circumstances was he to admit anything unless she told him to. The maid was in the kitchen out of ear shot, and Mrs. Hibberdell and Carlotta were in the library when the opening gun was fired. In a way Carlotta was prepared, for she fancied her mother might have seen other things--what or how much she could not guess. She was not without the dignity of a Circe, for she had been through scenes like this before. Her own husband had charged her with infidelity more than once, and she had been threatened with physical violence by him. Her face was pale but calm.
