When he reached the Mission, pressing work distracted his attention for some hours. He did it as thoroughly as usual, wondering what he should write to Betty when he was at liberty to go to his own room. He wondered also that his friends made no comment upon his appearance. Surely he carried scars. A small glass hung in the committee-room where he was sitting. He glanced at it. Outwardly he was unchanged.
Not till the clock struck nine did he find himself alone. He wrote a letter to Betty, a long letter, which he read and destroyed. The next letter was short, curt, cold: he burned this also. A few minutes later, feeling pain in his hands, he discovered that his nails had lacerated the flesh. Then he knew that a fight for life and reason was beginning. The demons were crying "Surrender!" If he died to-night, Betty would be free; if he lingered on for half a dozen years, she might deem herself bond to a dying man. Virility repudiated such a sacrifice.
"O God," he cried, "let me die to-night!"
Outside, the world of Whitechapel roared in derision. All Mark had known of poverty, of vice, of squalor, swelled into a chorus of despair. Here, in the heart of the slums, in an atmosphere tainted by the dead bodies of hundreds of thousands who had perished cursing God and man, he felt that he was choking for fresh air, that the pestilential fumes of every evil place into which he had entered were destroying him.
He sat down limply on the edge of his bed, wondering whether the end would come soon, telling himself that he was dead already. At any rate his work was done; he would leave the Mission on the morrow. The animal instinct to slink off to some lonely spot where none might witness his misery became overpowering. But a letter to Betty must be written first. He crossed to his desk, where Betty's face smiled out of a silver frame. Gazing at this, he became so absorbed that three sharp taps on the door were unheeded. The Bishop of Poplar entered the room, pausing when he saw the head bent over the table, the thin fingers clutching the silver frame. He closed the door, crossed the room, and laid his hand upon Mark's shoulder.
"You are in sore trouble."
Mark started to his feet with an exclamation compounded of fear and surprise.
"You—David——?" he stammered. "What b-brought you here?"
"You shall answer that question yourself," said Ross gravely.
The men confronted each other. Great as the contrast was between the robust health of the one and the infirmity of the other, a critical eye might have detected a similarity in the two faces—a resemblance the stronger because it was born of the spirit rather than the flesh.
