“Miss Austin,” she said, “let me present Doctor Waring. John,—Miss Anita Austin.”

At that very moment Helen Peyton offered Waring a cup of tea, and he was in the act of taking it from her hand when Mrs. Bates made the introduction.

The cup and saucer fell to the floor with a crash, and those nearest saw the Doctor’s face blanch suddenly white, and his hand clench on a nearby chair.

But with a sudden, desperate effort he pulled himself together, and gave a little laugh, as he directed Nogi to remove the wrecked teacup.

“Pick up the four corners, and carry it all off at once,” he ordered, pointing to the small rug on which the cup had fallen, and Nogi, a little clumsily, obeyed.

“Pardon the awkwardness, Miss Austin,” he said, turning to smile at the girl, but even as he did so, his voice trembled, and he turned hastily away.

“What is it, John?” asked Emily Bates, going to his side. “Are you ill?”

“No,—no, dear; it’s—it’s all right. That foolish teacup upset my nerves. I’ll go off by myself for a few moments.”

Somewhat abruptly, he left the room and went back to his study.

Listening intently, Mrs. Bates heard him lock the door on the inside.
