For reasons of his own Van Lennop finally decided to accept the invitation which at first thought he fully intended to refuse. He figured that he had time to telegraph for his clothes, and this he did with the result that Crowheart stared as hard almost at him as at Dr. Harpe's amazing transformation. The reserved, unapproachable stranger in worn corduroys, who had come to be tacitly recognized as an object of suspicion, was not readily reconciled with this suave, self-possessed young man in clothes which they felt intuitively were correct in every detail. He moved among them with a savoir-faire which was new to Crowheart, talking easily and with flattering deference to this neglected lady and that, agreeable to a point which left them animated and coquettish. He danced with Mrs. Terriberry, he escorted Mrs. Tutts to the punch bowl, he threw Mrs. Jackson's scarf about her shoulders with a gallantry that turned Jackson green, a neat compliment sent Mrs. Percy Parrott off in a series of the hysterical shrieks which always followed when Mrs. Parrott found herself at a loss for words. Long before Dr. Harpe's appearance it had begun to dawn upon Crowheart that in holding aloof in unfriendly suspicion the loss had been theirs, for it was being borne in even upon their ignorance that Van Lennop's sphere was one in which they did not "belong."

Dr. Harpe quickly demonstrated that she was easily the best dancer in the room, and there was no dearth of partners after the first awe of her had worn off, but her satisfaction in her night of triumph was not complete until Van Lennop's name was upon her programme.

Essie Tisdale, busy elsewhere, had her first glimpse of the ballroom where Van Lennop claimed his dance. She grew white even to her lips, and her knees shook unaccountably beneath her as she watched Dr. Harpe glide the length of the room in Van Lennop's arms. The momentary pain she felt in her heart had the poignancy of an actual stab. It was so—so unexpected; he had so unequivocally ranged himself upon her side, he had seen so plainly Dr. Harpe's illy-concealed venom and resented it in his quiet way, as she had thought, that this seemed like disloyalty, and in the first shock of bewilderment and pain Essie Tisdale was conscious only that the one person in all the world upon whom she had felt she could count was being taken from her.

Van Lennop had told her of his invitation in amusement and later had remarked carelessly that he might accept, but apparently had given it no further thought. Even in her unhappiness the girl was fair to her merciless enemy. She looked well—far, far more attractive than Essie would have believed possible, softer, more feminine and—more dangerous. Van Lennop was human; and, after all, as she was forced to recognize more and more fully, she was only the pretty biscuit-shooter of the Terriberry House. Essie Tisdale pushed the swinging doors from her with a shaking hand and managed somehow to get back into the kitchen where, as she thought, with a strange, new bitterness, she belonged.

Van Lennop did not leave Dr. Harpe when the waltz was done, but seated himself beside her, first parting the curtain that she might get the air and showing a solicitude for her comfort so different from the cold, impersonal courtesy of months that her heart beat high with triumph. Verily, this propitious beginning was all she needed and, she told herself again, was all she asked. While she believed in herself and her personal charm when she chose to exercise it, Van Lennop's tacit recognition of it brightened her eyes and softened her face into smiling curves of happiness.

Van Lennop toyed with her fan and talked idly of impersonal things, but there was a veiled look of curiosity in his eyes, a kind of puzzled wonder each time that they rested upon her face. As he covertly studied her altered expression and manner, strongly conscious of the different atmosphere which she created, there rose persistently in his mind Stevenson's story of the strange case of Dr. Jekyll and Mr. Hyde. He could not conceive a more striking example of dual personality or double consciousness than Dr. Harpe now presented. There was a girlish shyness in her fluttering glance, honesty in the depths of her limpid hazel eyes, while her white, unmarred forehead suggested the serenity of a good woman, and Van Lennop was dimly conscious that for some undefined reason he never had thought of her as that. She had personal magnetism—that he had conceded from the first, for invariably he had found himself sensible of her presence even when disliking her the most. To-night he was more strongly aware of it than ever.

"You are enjoying the evening?"

"Isn't that apparent?" A twinkle shone for a moment in his eyes. "And you?" adding quickly, "An unnecessary question—your face is the answer."

She laughed lightly.

"It doesn't belie me, for I like this—immensely. Flossying up occasionally helps me keep my self-respect. You didn't expect to find this sort of thing out here, did you?"
