The doctor smiled. "I am not going to do anything rash, and Miss Jo shall not know that I know anything about her cuttings up. I have a scheme which I hope will work out all right and rid you all of the undesirable acquaintance. Do you trust me?"
"Indeed I do. You are always such a rock of defense, Dr. Paul," said Nan gratefully. "I don't know what I should do without you."
"I'd be a pretty sort of cad if I didn't look out for you," he said vehemently. "I'd like to bring young Bingham with me to call, if I may. He is a nice fellow, I can assure you. Your Fräulein will not object?"
"Oh, no, though she is a very good watchdog. So long as he comes with you he will be admitted. I am not so sure but that she would growl and show her teeth if he came alone."
"All right, I will stop in or will telephone to-morrow and tell you when to expect us. Now, remember, no more anxiety over Miss Jo and Herr Green-Cap. You promise?"
"I promise." Nan held out her hand, and as the door closed after the doctor she felt a distinct sense of relief that he should have taken her burden on his own shoulders. She could not resist going over to call Mary Lee out into the hall for a whispered conversation before going back to her studies, for which, after all, she would not have to rise before daylight.
Just what the doctor meant to do the girls could not imagine, and they were very curious to discover. True to his word, he called Nan up over the telephone the next day and said that he and Mr. Bingham would call that evening, if convenient.
"I'll ask the Fräulein," said Nan, and presently that lady herself came to the 'phone. Of course any friend of the Herr doctor would be acceptable. Yes, she would be pleased to receive them. Therefore when evening came she was established in the place of honor, the sofa, some time before the two visitors arrived. The Hoyts were out, the twins had gone to bed, therefore there was no excuse for Jo not to be present. She had rather avoided being alone with the girls, and was relieved when company came. She felt the unspoken disapproval in the manner of both Mary Lee and Nan, and resented it, though, in her heart of hearts, she could not help knowing there was reason for it.
Mr. Bingham was a pleasant, ruddy-faced young man, who, as he hailed from the West, was looked upon with favor by Jo. As was natural the talk fell upon student life. Mr. Bingham, being a university man, was good authority, for he had been in Munich two years.
