"It is pitch dark till nearly eight in the morning."
"I can get a lamp and go into the sitting-room."
Mary Lee was so used to leaving such matters to her elder sister that she didn't at once think of protesting. Moreover she was not quite so unselfish as Nan; she did love her morning nap and was not ready to give up an evening's fun with the Hoyts. But at last she said, a little reluctantly: "Couldn't I write the letter, Nan?"
"No, thanks, I reckon I'd better do it," said Nan lightly, and Mary Lee felt relieved not only that she had made the offer but that it had not been accepted.
But after all, Nan did not have to write the letter that evening, for Dr. Paul came in early. He generally stopped for a few minutes every day to see that all was right with his wards, as he called the girls. Jo had come home late, when the others were already seated at the supper table. She gave Mary Lee a top-loftical glance but carried on a conversation principally with Juliet and Maurice.
"She doesn't like it because I wouldn't stay with her and meet that creature," Mary Lee whispered to Nan as they left the dining-room.
"I'm glad you had the good sense not to," said Nan. "Did he come home with her?"
"I suppose so, though I don't know any more about it than you do."
Jo had not tarried with the girls, but had gone directly to the Hoyts' room, to which Mary Lee declared her intention of going also.
"That letter has got to be written, I plainly see," said Nan.
She was about to settle herself to her task, the others having congregated around Mrs. Hoyt, when Dr. Paul came in. Nan greeted him in a preoccupied way.
"Am I interrupting some important study?" he asked.
"No," replied Nan. "I was just beginning a letter to mother; that was all."
"Everything all right?"
"Ye-es." She spoke a little doubtfully, the shadow of Jo's affair still upon her.
Dr. Paul looked at her fixedly, his keen eye noticing the trouble in her face. "Look here, Nan," he said. "I don't believe everything is all right."
Nan recovered herself and smiled. "Oh, yes, it is. You'll not find a Corner who hasn't a clear conscience and a clean bill of health."
"That's good. Then I've no prescriptions to write, no advice to give you this time?"
Nan shook her head. "No, you'll have to look out for other patients."
"Then I'll not keep you from that letter. I know how precious time is just now. Where are the rest?"
"Where they generally are; over in Mrs. Hoyt's room 'ca'y'in on' as Mitty would say."
The doctor picked up his hat. "After all, it was only that the girl was thinking about her work," he told himself. He knew she was practicing for a musicale which was to be given by Frau Burg-Schmidt's pupils, and that she had much to do. He was about to go when he turned back. "Listen, Nan," he said. "Who is the German youth with the green cap I saw skating with your friend Jo, this afternoon?"
"Were you out there? Oh, he is a friend of Jo's." She tried to speak lightly.
"Do you know him?"
Nan was silent, but the question was too direct to avoid. "No," she answered truthfully, then hurriedly, "Why do you ask?"
"Because I don't believe he is the kind you all want to know."
"What makes you think so?"
"Well, I'll tell you the whole thing. I was standing with a fellow student watching the skaters when Miss Jo swung along with Green-Cap. She saw me and I bowed. I don't think she saw my friend who was just behind me. 'Who is that?' said he. 'A young compatriot of ours,' I told him. 'Nice girl.' 'Humph!' he said. 'I wonder where she picked up that fellow.' 'What's the matter with him?' I asked. 'He is a bad lot,' said my friend. 'I shouldn't like a sister of mine to be seen with him.' Later on I happened to be coming home directly behind the couple. They were laughing and talking in great shape. I noticed that none of you were along, and I wondered; that's all."
Nan stood leaning on the back of a chair, listening thoughtfully. "Sit down, Dr. Paul," she said. "I don't believe I shall have to write that letter to-night, for you happen to bring up the very subject I was going to write about. No, we don't know that young man. He is a chance acquaintance whom Jo has picked up without realizing it was anything out of the way. He asked if he might skate with her, and she, thinking it the custom, accepted his invitation. Mary Lee, whom you know is always a most proper and discreet young person, came away and left Jo. Mrs. Hoyt believing him to be a friend of ours hasn't inquired about him. She is an awfully jolly sort of somebody, and is really particular, but I think she doesn't want to appear fussy, and of course doesn't dream but that we all know this person. So, Jo has been going her own gait, and I am awfully bothered about it. I don't want to tell tales to Mrs. Hoyt, and have her annoyed with Jo. I don't want to tell Fräulein Bauer, for fear she would say Jo could not stay here, for the Fräulein is a great stickler of proprieties, and I could see nothing to do but to write to mother, though I hate to bother her."
The doctor looked down at her with a sympathetic expression in his dark eyes. "You are always shouldering somebody's burdens, Nan," he said. "I haven't forgotten last year."
"Oh, that was quite a different thing."
"If I remember right, Miss Jo was mixed up in that."
"Yes, in a way," Nan admitted. "Though she hadn't the least idea that she was, and as soon as she found out, you know she went straight to Miss Barnes and told her all about it."
"And this time she is going into an affair with her eyes open."
"Not exactly. You know she is a Western girl who has not had much care at home. Her mother died before Jo was big enough to remember her, and though the stepmother is a kind enough sort of person, she has no thought beyond her family of little children and Jo has had to hoe her own row always. Her father is away from home a good deal and absorbed in business so Jo has not had much chance."
"I see, and you think that all the more she should be warned. Have you said anything to her on the subject?"
"No, but Mary Lee has, and she thinks she is prudish."
"Well, I tell you you are not to think of this any more. I will settle it. You must leave it all to me."
"But you will not – " Nan began in alarm.
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.
"Do you know many of the students?" he asked Nan.
"Not one," she replied, "unless you can call Dr. Woods a student. We know a number of Dr. Mann's schoolboys, but you're the first real student we have met. I am glad you haven't let them slash your face."
