Throughout the voyage his bodily health and strength were steadily, though slowly, on the mend. He put on a little flesh; there was a little more brightness in his eye and more clearness of skin than when he left England, and this, too, seemed to her a visible sign of the truth of what she believed. With all her heart, too, she set herself to reverse and forget the warning that Sir James had given her, that as his strength began to return so the strength of his craving would grow also. It had, indeed, seemed that this was true on that first evening when he had taken the drug again--or, at least, he had felt and said that it was so--but she set herself to fight that. With heart lifted high in faith and hope, she denied it, affirming that, his health being a good thing, it could not let itself give aid and be a slave to an evil thing, for thus evil would be mastering good--a thing unthinkable. No; the strength that was coming back to him, slowly indeed, represented the efforts against, and the repulses of, that deadly habit which had become so intimate a guest of his soul. Into the house of his soul he had admitted it, a hideous, dwarfish shape, but of terrible strength, blear-eyed, and with trembling hands, clothed in the shroud and cerements of sensuality. But now he was pushing it away again, dragging it out of the home of his spirit. It was hard work--none knew that better than she--for the thing clung as tenaciously as a limpet; but failure was impossible, and well she knew that, when at last they got it to the door of his soul, and got that door open so that the sunshine of Infinite Love poured in, with what cry of joyful amazement would he see that the dreadful figure that in the dark seemed so real was nothing, had no existence apart from his belief in it. It was cheating him all the time. It was only in the twilight of his soul that what was a shadow seemed to be real. Now and then, too, the real Thurso--the kindly, courteous gentleman who had been to her so well-loved a brother--came back, and he and Maud would talk about old days before ever this shadow blackened his path. And then in the serene light of memory, which often lends a vividness to that which is remembered that it did not have in life, they would live over again some windy, notable day on the hill when Thurso shot three stags, or some memorable morning by the river when Maud killed four salmon before lunch. "Oh, Thurso, and I should have killed the fifth, do you remember? but I let the line get round that rock in the Roaring Pool, and he broke me." "By gad! yes," he said. "And you very nearly cried. Lord, what good days they were! I was awfully happy all that summer. Funny--I had hideous neuralgia, and it spoiled my pleasure a good deal, but it didn't spoil my happiness. What do you make of that?" "Why, nothing can spoil one's happiness," she said, "if one thinks right. All happiness----" But he got up suddenly. "I get the heartache to think of it all," he said.
