"Well, Roberts, I want to take her place."

"You want----" and Roberts' voice failed him in his astonishment.

"Yes, I want to take her place, Roberts. I should think that if you or Andrew were to tell her that you have a friend up from the country who wants just such a place, and is ready to pay five pounds to get one, she might be ready to take the offer; especially as you might say that you knew of a lady who is in want of an under-housemaid and you thought that you could get her the place."

"As to that, miss, I have no doubt that she would leave to-morrow, if she could get five pounds. She told Andrew that she hated London, and should go down home and take a country place as soon as she had saved up money to do so."

"All the better, Roberts; then all she would have to do would be to say that she had heard of a place near home, and wanted to leave at once.

She did not wish to inconvenience them, but that she had a cousin who was just coming up to London and wanted a place, and that she would jump at it. She could say that her cousin had not been in service before, but that she was a thorough good cleaner and hard worker."

"And do you mean that you would go as a servant, Miss Netta? Why, it would not be right for you to do so."

"Anything would be right that led to the discovery of Walter's hiding place, Roberts. I have been accustomed to teaching, and I have helped my aunt to look after the house for years, and I do not in the slightest degree mind playing the part of a servant for a short time, in order to try and get at the bottom of this matter. You think that it can be managed?"

"I am sure it can be managed right enough, miss; but what Miss Covington would say, if she knew that I had a hand in bringing it about, I can't say."

"Well, you won't be drawn into the matter. I shall say enough to my aunt to satisfy her that I am acting for the best, and shall simply, when I go, leave a note for your mistress, telling her that I have gone to work out an idea that I have had in my mind, and that it would be no use for her to inquire into the matter until she hears of me again."

"What am I to tell Andrew, miss?"

"Simply tell him that a young woman has been engaged to watch Simcoe in his lodgings. Then tell him the story he has to tell the girl. I shall want three or four days to get my things ready. I shall have to go to a dressmaker's and tell her that I want three or four print gowns for a young servant about my own figure, and as soon as they are ready I shall be ready, too."

"Well, miss, I will do as you tell me, but I would say, quite respectful, I hope that you will bear in mind, if things goes wrong, that I was dead against it, and that it was only because you said that it was our only chance of finding Master Walter that I agreed to lend a hand."

"I will certainly bear that in mind," Netta said with a smile. "Talk it over with Andrew to-night; but remember he is only to know that a young woman has been engaged to keep a watch on Simcoe."

"He will be glad enough to hear, miss, that someone else is going to do something. He says the Colonel is so irritable because he has found out so little that there is no bearing with him."

"The Colonel is trying," Netta laughed. "As you know, he comes here two or three times a week and puts himself into such rages that, as he stamps up and down the room, I expect to hear a crash and to find that the dining-room ceiling has fallen down. He is a thoroughly kind-hearted man, but is a dreadful specimen of what an English gentleman may come to after he has had the command of an Indian regiment for some years, and been accustomed to have his will obeyed in everything. It is very bad for a man."

"It is a good deal worse for his servant, miss," Tom Roberts said, in a tone of deep sympathy for his comrade. "I doubt whether I could have stood it myself; but though Andrew expresses his feelings strong sometimes, I know that if you offered him a good place, even in Buckingham Palace, he would not leave the Colonel."

Two days later Netta heard that the girl in Jermyn Street had joyfully accepted the offer, and had that morning told her master that she had heard that she was wanted badly at home, and that a cousin of hers would be up in a day or two, and would, she was sure, be very glad to take her place. The master agreed to give her a trial, if she looked a clean and tidy girl.

"I shall be clean and tidy, Roberts; and I am sure I shall do no injustice to her recommendation."

Roberts shook his head. The matter was, to his mind, far too serious to be joked about, and he almost felt as if he were acting in a treasonable sort of way in aiding to carry out such a project.

On the following Monday Hilda, on coming down to breakfast, found a note on the table. She opened it in haste, seeing that it was in Netta's handwriting, and her eyes opened in surprise and almost dismay as she read:

"MY DARLING HILDA: I told you that I had a plan. Well, I am off to carry it out. It is of no use your asking what it is, or where I am going. You will hear nothing of me until I return to tell you whether I have failed or succeeded. Aunt knows what I am going to do."

Hilda at once ran upstairs to Miss Purcell's room.

"Where has Netta gone?" she exclaimed. "Her letter has given me quite a turn. She says that you know; but I feel sure that it is something very foolish and rash."

"I thought that you had a better opinion of Netta's common sense," Miss Purcell said placidly, smiling a little at Hilda's excitement. "It is her arrangement, dear, and not mine, and I am certainly not at liberty to give you any information about it. I do not say that I should not have opposed it in the first instance, had I known of it, but I certainly cannot say that there is anything foolish in it, and I admit that it seems to me to offer a better chance of success than any plan that has yet been tried. I don't think there is any occasion for anxiety about her. Netta has thought over her plans very carefully, and has gone to work in a methodical way; she may fail, but if so I don't think that it will be her fault."

"But why could she not tell me as well as you?" Hilda asked rather indignantly.

"Possibly because she did not wish to raise hopes that might not be fulfilled; but princ.i.p.ally, I own, because she thought you would raise objections to it, and she was bent upon having her own way. She has seconded you well, my dear, all through this business."

"Yes, I know, aunt; she has been most kind in every respect."

"Well, my dear, then don't grudge her having a little plan of her own."

"I don't grudge her a bit," Hilda said impetuously, "and, as you are quite satisfied, I will try to be quite satisfied too. But, you see, it took me by surprise; and I was so afraid that she might do something rash and get into trouble somehow. You know really I am quite afraid of this man, and would certainly far rather run a risk myself than let her do so."

"Of that I have no doubt, Hilda; but I am quite sure that, if the case had been reversed, you would have undertaken this little plan that she has. .h.i.t upon, to endeavor to relieve her of a terrible anxiety, just as she is doing for you."

"Well, I will be patient, aunt. How long do you think that she will be away?"

"That is more than I can tell you; but at any rate she has promised to write me a line at least twice a week, and, should I think it right, I can recall her."

"That is something, aunt. You cannot guess whether it is likely to be a week or a month?"

Miss Purcell shook her head.

"It will all depend upon whether she succeeds in hitting upon a clew as to where Walter is. If she finds that she has no chance of so doing she will return; if, on the other hand, she thinks that there is a probability that with patience she will succeed, she will continue to watch and wait."

"Miss Netta is not ill, I hope, miss?" Roberts said, when he came in to clear the breakfast things away.

"No she has gone away on a short visit," Hilda replied. Had she been watching the old soldier's face, she might have caught a slight contortion that would have enlightened her as to the fact that he knew more than she did about the matter; but she had avoided looking at him, lest he should read in her face that she was in ignorance as to Netta's whereabouts. She would have liked to have asked when she went; whether she took a box with her, and whether she had gone early that morning or late the evening before; but she felt that any questions of the sort would show that she was totally in the dark as to her friend's movements. In fact Netta had walked out early that morning, having sent off a box by the carrier on the previous Sat.u.r.day when Hilda was out; Roberts having himself carried it to the receiving house.

It was four or five days before Dr. Leeds called again.

"Is Miss Purcell out?" he asked carelessly, when some little time had elapsed without her making her appearance.

"Is that asked innocently, Dr. Leeds?" Hilda said quickly.

The doctor looked at her in genuine surprise.

"Innocently, Miss Covington? I don't think that I quite understand you."

"I see, doctor, that I have been in error. I suspected you of being an accomplice of Netta's in a little scheme in which she is engaged on her own account." And she then told him about her disappearance, of the letter that she had received, and of the conversation with her aunt.

Dr. Leeds was seriously disturbed.

"I need hardly say that this comes as a perfect surprise to me, Miss Covington, and I say frankly a very unpleasant one. But the only satisfactory feature is that the young lady's aunt does not absolutely disapprove of the scheme, whatever it is, although it is evident that her approval is by no means a warm one. This is a very serious matter. I have the highest opinion of your friend's judgment and sense, but I own that I feel extremely uneasy at the thought that she has, so to speak, pitted herself against one of the most unscrupulous villains I have ever met, whose past conduct shows that he would stop at nothing, and who is playing for a very big stake. It would be as dangerous to interfere between a tiger and his prey as to endeavor to discover the secret on which so much depends."

"I feel that myself, doctor, and I own that I'm exceedingly anxious.

Aunt has had two short letters from her. Both are written in pencil, but the envelope is in ink, and in her usual handwriting. I should think it probable that she took with her several directed envelopes. The letters are very short. The first was: 'I am getting on all right, aunt, and am comfortable. Too early to say whether I am likely to discover anything.

Pray do not fidget about me, nor let Hilda do so. There is nothing to be uneasy about.' The second was as nearly as possible in the same words, except that she said, 'You and Hilda must be patient. Rome was not built in a day, and after so many clever people have failed you cannot expect that I can succeed all at once.'"

"That is good as far as it goes," the doctor said, "but you see it does not go very far. It is not until success is nearly reached that the danger will really begin. I do not mind saying to you that Miss Purcell is very dear to me. I have not spoken to her on the subject, as I wished to see how my present partnership was likely to turn out. I am wholly dependent upon my profession, and until I felt my ground thoroughly I determined to remain silent. You can imagine, therefore, how troubled I am at your news. Were it not that I have such implicit confidence in her judgment I should feel it still more; but even as it is, when I think how unscrupulous and how desperate is the man against whom she has, single-handed, entered the lists, I cannot but be alarmed."

"I am very glad at what you have told me, doctor. I had a little hope that it might be so. It seemed to me impossible that you could be living for four months with such a dear girl without being greatly attracted by her. Of course I know nothing of her feelings. The subject is one that has never been alluded to between us, but I am sure that no girl living is more fitted than she is to be the wife of a medical man. I would give much to have Netta back again, but Miss Purcell is obdurate. She says that, knowing as she does what Netta is doing, she does not think that she is running any risk--at any rate, none proportionate to the importance of finding a clew to Walter's hiding place."

"Will you ask her if she will write to her niece and urge her to return, saying how anxious you are about her? Or, if she will not do that, whether she will release her from her promise of secrecy, so that she may let us know what she is doing?"
