"I believe," she said, turning to him, "that I know how I can find out all about it—from a trustworthy source," she added, smiling gravely, "as Miss Lambkin would put it."

Doctor Beatty had been gone but a few minutes when Horry Carling came in. He nodded pleasantly to Sally and was taking off his overcoat.

"Wh—wh—what?" he asked at last.

"W—w—well, y—y—yes," Horry stammered, getting rather red, "I th—th—think h—he h—h—has."
