There was no more to be said. Kate Charlock flung herself back in an armchair and closed her eyes. When she opened them again she was alone. Her tears had vanished. The fatigue she had spoken of seemed to fall from her like a garment. She crossed rapidly over to the writing-table, and in her clear, bold hand began a letter. It was a fairly long letter, but it was finished at length and addressed to Mrs. Rent. Kate proceeded to put it in a conspicuous place and very quietly passed into the hall and took down her hat and long travelling wrap. A few moments later she was walking rapidly down the avenue in the direction of the road. Her face was clear and bright. There was something like a smile in her starry eyes; her heart was free from fear.
Meanwhile, the conference in the drawing-room was finished. Arnold was standing pale and stern by the side of his mother as Ethel entered. He hardly appeared to notice her at all, beyond a sullen nod which brought the blood flaming to the girl's face. Very quietly she made her explanation.
"Oh, we have settled that," Arnold laughed bitterly. "It is I who am going away. I can walk as far as the station and stay in the waiting-room for the early express. Then, to-morrow, Mrs. Charlock must do as she pleases. I am certain that she will lose no time in ridding you of her detestable presence."
"I do not like to hear you speak like that," Mrs. Rent said. "Ethel, will you go and ask the lady if she will come this way for a moment? I should like her to feel——"
There was an uncomfortable pause for a few moments till Ethel came back with a letter in her hand.
"I cannot understand it at all," she said. "Mrs. Charlock has disappeared. Her wraps have vanished from the hall, too. She seems to have left this letter behind, which is addressed to you, aunt. After the way she spoke to me just now I am not surprised to find that she has not felt equal to the ordeal of staying here even for a single night."
"It was a fatal mistake," Arnold said hoarsely. "I see it all now. Only it is too late to rectify matters."
Mrs. Rent reached for the letter and slowly broke the seal. She read aloud so that the others could hear:
"All I can say is, forgive me. It was wrong to come, and I can stay no longer. Though I am without friends, I am not without resources, for I have a little to assist me. And yet I am glad to have seen you all, even if it has been only to convince you that I am not the hard, brazen, calculating creature you took me to be. I am going away till I am free. I shall not look upon any of you again till I am ready to send for Arnold. I want no money or favour now, nor in the future. I want to show that I have given my heart to one who will be able to support me without help from anyone. To be in receipt of your favours would ruin the whole romance of the situation. Perhaps later, when I have proved myself, it may be possible—but I can write no more."
The paper slipped from Mrs. Rent's fingers and lay upon the carpet. The eyes that she turned upon her son were troubled and haggard. He turned away with a passionate gesture.
