Duncan waited in the cab, when they went into the big building. She was gone almost half an hour. Darkness came, and a sharp rain began to fall.

He was half drowsy when she suddenly ran down the long steps and jumped in beside him. Her face was radiant, in spite of the signs of tears about her eyes.

"He took the ether like a little soldier!" she said, as the motor-car slowly wheeled up the wet street. "Mary held his hand all the while. Everything went splendidly, and he came out of it at about four. Mary sang him off to sleep, sitting beside him, and she's still there—he hasn't stirred! Dr. Thorpe is more than well satisfied; he said the little fellow had nerves of iron! And the other doctor isn't even going to come in again! And Thorpe says it is LARGELY because he could have his mother!"

But the exhilaration did not last. Presently she leaned her head back against the seat, and Duncan saw how marked was the pallor of her face, now that the rouge was gone. There was fatigue in the droop of her mouth, and in the deep lines etched under her eyes.

"It's after six, Duncan," she said, without opening her eyes, "so I can't sleep, as I hoped! We'll have to dine, and then go straight to the theatre!"

"You're tired," said the boy, abruptly. She opened her eyes at the tone, and forced a smile.

"No—or, yes, I am, a little. My head's been aching. I wish to-night was over." Suddenly she sighed. "It's been a strain, hasn't it?" she said. "I knew it would be, but I didn't realize how hard! I just wanted to do something for them, you know, and this was all I could think of. And I've been wishing your father had been here; I don't know what he will say. I don't stop to think—when it's the people I love—" she said artlessly. "I dread—" she began again, but left the sentence unfinished, after all, and looked out of the window. "I suspect you're tired, too!" she went on brightly, after a moment. "I shan't forget what a comfort it's been to have you with me through this queer experience, Duncan. I know what it has cost you, my dear."

"Comfort!" echoed Duncan. He tried to laugh, but the laugh broke itself off gruffly. He found himself catching her hand, putting his free arm boyishly about her shoulders. "I'm not fit to speak to you, Margaret!" he said huskily. "You're—you're the best woman I ever knew! I want you to know I'm sorry—sorry for it all—everything! And as for Dad, why, he'll think what I think—that you're the only person in the world who'd do all this for another woman's kid!"

Mrs. Coppered had tried to laugh, too, as she faced him. But the tears came too quickly. She put her wet face against his rough overcoat and for a moment gave herself up to the luxury of tears.

"Carey," said his wife, on a certain brilliant Sunday morning a month later, when he had been at home nearly a month. She put her head in at the library door. "Carey, will you do me a favor?"
