"I cannot wait for Dr. Leeds to come round," Hilda said the next morning at breakfast. "You and I will pay him a visit in Harley Street. I am sure that he will not grudge a quarter of an hour to hear what you have done."

"What mystery are you two girls engaged in?" Miss Purcell asked, as she placidly poured out the tea.

"It is a little plot of our own, aunt," Netta said. "We are trying to get on Walter's track in our own way, and to be for a time amateur detectives. So far we have not found any decisive clew, but I think that we are searching in the right direction. Please trust us entirely, and we hope some day we shall have the triumph of bringing Walter back, safe and sound."

"I pray God that it may be so, my dear. I know that you are both sensible girls, and not likely to get yourselves into any silly scrape."

"I don't think we are, aunt; but I am afraid that neither of us would consider any scrape a foolish one that brought us even a little bit nearer to the object of our search. At any rate, aunt, it will reassure you to know that we are acting in concert with Dr. Leeds, of whom I know that you entertain the highest opinion."

"Certainly I do. Of course I am no judge whatever as to whether he is a good doctor, but I should think, from what Dr. Pearson says, that he must, in the opinion of other medical men, be considered an exceptionally clever man for his age; and having seen him for four months and lived in close contact with him, I would rather be attended by him than by anyone else I have ever met. His kindness to the General was unceasing. Had he been his son, he could not have been more patient and more attentive. He showed wonderful skill in managing him, and was at once sympathetic and cheerful. But, more than that, I admired his tact in filling the somewhat difficult position in which he was placed. Although he was completely one of the family, and any stranger would have supposed that he was a brother, or at least a cousin, there was always something in his manner that, even while laughing and chatting with us all, placed a little barrier between us and himself; and one felt that, although most essentially a friend, he was still there as the General's medical attendant.

"It was a difficult position for a man of his age to be placed in. Had he been like most of the doctors we knew in Germany, a man filled with the idea that he must always be a professor of medicine, and impressing people with his learning and gravity, it might have been easy enough. But there is nothing of that sort about him at all; he is just as high-spirited and is as bright and cheerful as other young men of about the same age, and it was only when he was with the General that his gentleness of manner recalled the fact that he was a doctor. As I say, it was a difficult position, with only an old woman like myself and two girls, who looked to him for comfort and hope, who treated him as if he had been an old friend, and were constantly appealing to him for his opinion on all sorts of subjects.

"I confess that, when he first came here with Dr. Pearson, I thought that it was a very rash experiment to introduce a young and evidently pleasant man to us under such circumstances, especially as you, Hilda, are a rich heiress and your own mistress; and feeling as I did that I was in the position of your chaperon, I must say that at first I felt very anxious about you, and it was a great relief to me when after a time I saw no signs, either on his part or yours, of any feeling stronger than friendship springing up."

Hilda laughed merrily.
