Grover began to feel apprehensive that she had taken leave of her senses. The disappointment, the shock to her cherished hopes, had perhaps been too much for her. He arose a little tremblingly and offered her his hand. "I am your most obedient servant, Frau Professorin," he remarked, bowing deeply, and backing toward the door. "We shall no doubt have the pleasure of seeing you soon again, Mr. Grover," she observed, eyeing him with curious significance. "You are very kind," he murmured, and made haste to vanish. II. It was only three days later that Grover received an invitation to dine at Professor Bornholm's. He had spent the intervening period in meditation concerning Mrs. Bornholm's curious behavior. That she had something on her mind was obvious, and he had no doubt that he would to-day discover what it was. He felt confident that she had been plotting against him and had some dramatic surprise in store for him. As he rang the door-bell he had need of all his _sang froid_ to quiet his turbulent heart. He was admitted to the inner sanctuary and was greeted with studious cordiality by the three goddesses. They seemed all agitated and expectant, though they were striving to appear unconcerned. They lounged and chatted as people do in the introductory scene of a play, with hidden reference to some plot which has yet to be disclosed. To all appearances the plot had some connection with the door to the Professor's study, which, contrary to custom, was closed. Minchen repeatedly threw furtive glances at it, and Roeschen made her determination not to look at it equally conspicuous; only Gretchen was frankly curious and made no effort to disguise it. A strange sense of the unreality of the whole scene, himself included, crept over the young man; he felt like a man in a play who can murder or make love with equal irresponsibility. He was about to indulge in the latter diversion, when suddenly the mysterious door opened, and the Frau Professorin entered with much dramatic _eclat_, leading a lovely dark-eyed young girl by the hand. The eyes of the three goddesses grew as big as saucers, and Roeschen pressed her hand to her heart and nearly fainted from excitement. "Mr. Grover," said the Frau Professorin, making a most elaborate bow, "allow me to present--Miss Jones."
