Suddenly it flashed over Constance that Drummond might not be seeking the reward primarily, after all. His first object might be shielding Preston. She recollected that Mr. Gibbons had said nothing about Drummond, either one way or the other.

She rang the elevator bell.

"Has anybody called at my apartment while I was out?" she asked.

"Yes'm. A man came here."

"And then what?" inquired Constance breathlessly.

"Well, in about five minutes my bell rang. I ran the elevator up again, and, waiting, was this man with a girl I had never seen before. You understand—I thought it was all right—he told me he was going to meet some one."

"Yes—yes. I understand. Oh, my God, if I had only thought to leave word not to let her go. How did she look?"
