"Off we start," said the boy. "I want to know who that gentleman is who went into the house you have just left?" "That gent as let himself in with his latch-key. Oh, that's Mr. Felix." "It's not true," said Emilia. "Oh, you're going to cry off, are you? I call that mean, I do. I tell you it's Mr. Felix." Emilia considered a moment. What more likely than that Leonard Paget was living there under an assumed name? "Are you sure? Here is the first shilling." "Cock sure. Why, he's lived there years and years, and there's nobody in the house but him. There's a housekeeper, Mrs. Middlemore; she took in a loaf from me." "Does this Mr. Felix live there regularly?" "I see him regularly, so he lives there regularly. Anything more I can do for you?" "No, thank you; here is your other shilling." "Thank you." And the boy walked off, whistling. CHAPTER XL. DR. PETERSSEN REAPPEARS ON THE SCENE. 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.
