Dr. Harpe did not come down until the evening was well along, but the delay produced the effect she intended. As she appeared, fresh and cool with her hair in perfect order, at the end of a number which left the dancers red and dishevelled, she caused a sensation that could not well have been otherwise than flattering. Crowheart stared in candid amazement and admiration. Her sheer, white gown fell from sloping, well powdered shoulders and its filminess softened wonderfully the lines which were beginning to harden her face. She had dressed with the eagerness of a debutante, and her eyes were luminous, her cheeks delicately flushed with the excitement of it and with happiness at the visible impression she was making. Dr. Harpe could, upon occasions, assume an air which gave her a certain distinction of carriage and manner which was the direct antithesis of the careless, swaggering, unfeminine creature that Crowheart knew, and as she now came slowly into the ballroom it is little wonder that a buzz went round after the first flattering silence of astonishment, for even a stranger would have singled her out at a glance from the perspiring female crudities upon the floor. She looked younger by years and with that unexpected winsomeness which was her charm. The murmur of approval was a tribute to her femininity that was music in her ears. The night promised to be one of triumph which she intended to enjoy to the utmost, but to her it ensured more than that, for Ogden Van Lennop was there, as she had seen in one swift glance, and it meant, perhaps, her "chance." 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."
