For the unexpected good fortune of this discovery Emilia was very grateful, and her mind was now occupied in considering how to make the best use of it. She did not linger in Gerard Street lest she should be seen by Gerald's brother, but before she left it she ascertained that he was known not as Mr., but as Monsieur Felix. For what reason had he concealed his right name? For what reason had he assumed that of a foreigner? It was perhaps because she had but one subject to think of, but one supreme end to attain, that she mentally decided that she herself was not unconnected with his motive for concealing his identity. If that were the case it would be difficult indeed to obtain an interview with him. If she presented herself in person, or sent up her name, he would refuse to receive her; if she forced herself upon him he would not listen to her, and the next time she went to him she would find that he had flown. Thus her mission would be a failure and the unhappiness of her daughter insured. It behooved her to be very careful in her movements; the least slip would be fatal.
The whole of that day and the whole of the next she bent her mind to the consideration of the peculiar position in which she was placed. She did not remain at home; she spent many hours in the vicinity of Soho, making inquiries of M. Felix's habits and character, in such a manner as to draw no suspicion upon herself. Small tradesmen of whom she made purchases were the medium of these inquiries, and they were able to give her much information because of the gossiping disposition of Mrs. Middlemore, the housekeeper. It was at this time that she developed a talent for intrigue. To insure that she should not be recognized by M. Felix in a chance meeting in the streets, she took a room that was to let midway between Soho and the apartments occupied by herself, stating that she was an actress; and at one shop in the Strand, and at another in a street running out of that thoroughfare, she purchased a box of "make-up" and a wig of a different color from her own hair. It was a short wig, and when her own locks were concealed beneath it, and she had used certain pigments on her face, no one who knew her as Emilia Braham could possibly recognize her. These changes were made in the room she had taken unknown to Constance, and she gave no person in the house an opportunity of observing her. Independent, however, of these changes she was no further advanced at the end of the second day than when she met M. Felix in Regent Street, and she could think of no means of obtaining the interview she desired.
On the third day she went out again in the direction of Gerard Street, drawn thither, as it were, by a magnetic current. But indeed all her hopes, and the future of herself and child, were centred in the house in which Gerald's brother lived under the name of M. Felix. Snow was still falling heavily, but she did not shrink from the chill blasts which swept through the narrow spaces of Soho. She had struck up an acquaintance with the mistress of a shop in which foreign provisions were sold, and she was now standing before the counter conversing with the woman, and picking up further information of the domestic habits which reigned in M. Felix's house. She learnt that it was Mrs. Middlemore's custom to go out every night for her supper-beer at half-past eleven, and that she was generally absent for not less than half an hour. A wild plan instantly suggested itself; she felt that something must be done, and that she must be bold. At eleven o'clock this very night she would be on the watch outside the house in Gerard Street, waiting for the housekeeper to go upon her usual nightly errand. Then she would go up to her, before she closed the street-door, and say she came by appointment to see M. Felix. She had already ascertained that he occupied apartments on the first floor; she had seen on the previous night the lights shining through his windows, and she would know in the same way on this night whether he was at home. If she played her part well, and controlled her voice so that it did not betray her, the housekeeper would doubtless take her word, and thus she would obtain entrance to the house without M. Felix being aware of it. As to what she should do when she confronted him she was as yet undecided, but certain unformed ideas loomed in her mind which seemed to give her hope that this nocturnal visit would not be fruitless. It would be necessary, however, that she should not present herself to the housekeeper dressed as a woman, for that would almost certainly bring suspicion upon her. In the disguise of a man her story would be more credible. Well, she would buy a suit of male clothing, and so disguise herself. The moral energy by which she was supported caused her to accept any suggestion, however daring and bold, by means of which she could attain success.
She went out of the provision shop full of the scheme, but had not gone ten yards before she made a discovery which occasioned her as much surprise as her meeting with Gerald's brother a couple of days ago. A man brushed quite closely to her, and this man was none other than Dr. Peterssen. Another fateful thread in her sad story. What did his presence in that locality portend?
He took no notice of her as he passed, but lingered before the window of the provision shop, looking through the panes, not at the goods displayed, but into the shop to see who was there. Throughout this series of adventures Emilia's senses were preternaturally sharpened, and nothing escaped her which seemed to bear upon her sad story. Presently Dr. Peterssen entered the shop, and without a moment's hesitation Emilia followed him.
He had already commenced a conversation with the mistress of the establishment, who, saying to him, "I beg your pardon," went to Emilia.
"I have forgotten something I wanted to buy," said Emilia, in a low tone, "but I can wait till you have attended to that gentleman."
She took care that her voice should not reach his ears, and as the woman stepped toward him she turned her back, with the air of a person who was not in the least interested in his business. The first words she spoke caused Emilia's heart to beat violently; but she still kept her face from him.
"Yes, sir, M. Felix lives very near here, in the next street."
"Thank you," said Dr. Peterssen. "It was very careless of me to lose the letter he sent me containing his address. Would you mind writing it down on paper for me?"
"Not at all, sir."
The woman wrote the address, and Dr. Peterssen, thanking her, left the shop. Then she asked Emilia what she wished; it was common enough for people to come and ask the address of persons living in the neighborhood, and she attached no importance to it. Emilia made another small purchase, and again took her departure.
Instead of leaving Soho, as was her original intention, to buy the suit of man's clothing necessary for the carrying out of her scheme, she walked slowly through Gerard Street. Dr. Peterssen was on the opposite side of the road to that on which M. Felix's house was situated, and he was gazing up at the windows with an expression of triumph on his face. There had been a note of triumph also in his voice when he had thanked the shopkeeper for the information she gave him, and Emilia judged from those signs that he, as well as herself, had been hunting for M. Felix. For what reason, and why, had M. Felix hidden himself from a man he knew so well? Here again Emilia did not stop to reason. In the selfishness of the task upon which she was engaged she jumped at conclusions, and the conclusion she formed now was that Dr. Peterssen's search for M. Felix was in some way connected with herself and the husband she had lost.
No detective could have acted more warily than she. With extreme caution she watched Dr. Peterssen's movements. He stood for a few moments looking up at the windows, then he crossed the road, and noted the number of the house, and then, with an............
