Alone, and lying idle in bed, it was but natural--it was almost inevitable--that the doctor's thoughts should begin to run upon the strange events and suspicions of the past two days; and their current setting strongly in one channel, made him long to be resolved whether or no the Man of the Crowd, the author of yesterday's outrage, the "M. Dolaro" of whom the detective had gone in search, and who, if captured, would be certainly overwhelmed with contumely, if not with punishment,--whether or not that strange creature was Julius's father, or any relation at all of Julius. He was not clear how he could well put the matter to Julius, since he so evidently shrank from discourse upon it, yet he thought some kind of certainty might be arrived at from an interview with him. On the chance of his having returned to his chambers, he called for pen and paper and wrote a note, asking him to look in, as he would be resting all day. "Try to come," he urged; "I have something important to speak about." This he sent by the trusty hand of his man in black; and by mid-day Julius was announced. He came in confident, and bright as sunshine (Lefevre thought he had never seen him looking more serene); but suddenly the sunshine was beclouded, and Julius ceased to be himself, and became a restless, timorous kind of creature, like a bird put in a cage under the eye of his captor. "What?" he cried when he entered, with an eloquent gesture. "Lazying in bed on such a day as this? What does this mean?" But when he observed the pallor and weakness of Lefevre's appearance, he paused abruptly, refrained from the hand stretched out to greet him, and exclaimed in a tone of something like terror, "Good heavens! Are you ill?" A paleness, a shudder, and a dizziness passed upon him as if he sickened. "May I," he said, "open the window?" "Certainly, Julius," said Lefevre, in surprise and alarm. "Do you feel ill?" "No--no," said Julius from the window, where he stood letting the air play upon his face, and speaking as if he had to put considerable restraint upon himself. "I--I am unfortunately, miserably constituted: I cannot help it. I cannot bear the sight of illness, or lowness of health even. It appals me; it--it horrifies me with a quite instinctive horror; it deadens me."
