“Why,” she cried, stepping back, “you are ill yourself.”

“No,” he answered shortly, drawing himself up in his old reserved manner. “I had but little sleep last night, but I am not ill. What do you want, Polly?”

“O don’t you know what I want? You, of all the town, have said he was an impostor! To you then I come as to my only hope; speak, speak, is he not my father?”

The doctor with a side glance at Clarke, who had remained in the background, drew the girl’s hand within his arm and led her a few steps away. But it seemed an involuntary movement on his part, for he presently brought her back within easy earshot of her lover.

“He does not look to me like Ephraim Earle,” he was saying. “He has not his eyes, nor does his voice sound familiar. I do not see why any one acknowledges him.”

“But they can’t help it. He knows everybody, and everything. I—I thought you had some good reason, Dr. Izard, something that would make it easy for me to deny his claims.”

“You—” The doctor’s sleepless night seemed to have had a strange effect upon him, for he stammered in speaking, he who was always so cold and precise. “You thought—” he began, but presently broke into that new, strange laugh of his, and urging Polly towards her lover, he addressed his questions to the latter. “Does this man,” he asked, “make a serious claim upon the Earle name and its rights?”

Clarke, who was always sensible when in Dr. Izard’s presence of something intangible but positive acting like a barrier between them and yet who strangely revered the doctor, summoned up his courage and responded with the respect he really felt.

“Yes,” said he; but with a certain reserve, “that is our best reason perhaps for believing him. He promises not to molest Polly, nor to make any demands upon her until she herself recognizes her duty.”

The frown which darkened the doctor’s face deepened.
