Such thoughts came, and went; and below them all strained the fibers of an unseen cord that dragged mercilessly at his heart, and that he cursed bitterly in the moments when he could not deny to himself that it was there.... The folly, the useless, pitiable folly of it! In twenty-four hours his feeble roots in Paris had been torn out. He was looking over a leaden sea at the shining fortress-wall of the Dover cliffs. * * * * * But though he had instinctively picked out the lines of a set purpose from among the welter of promptings in his mind, he found it delayed at the very outset. He had decided that he must first see Mr. Cupples, who would be in a position to tell him much more than the American knew. But Mr. Cupples was away on his travels, not expected to come back for a month; and Trent had no reasonable excuse for hastening his return. Marlowe he would not confront until he had tried at least to reconnoiter the position. He constrained himself not to commit the crowning folly of seeking out Mrs. Manderson's house in Hampstead; he could not enter it, and the thought of the possibility of being seen by her lurking in its neighborhood brought the blood to his face. He stayed at a hotel, took a studio, and while he awaited Mr. Cupples' return attempted vainly to lose himself in work. At the end of a week he had an idea that he acted upon with eager precipitancy. She had let fall some word, at their last meeting, of a taste for music. Trent went that evening, and thenceforward regularly, to the opera. He might see her; and if, in spite of his caution, she caught sight of him, they could be blind to each other's presence--anybody might happen to go to the opera. So he went alone each evening, passing as quickly as he might through the people in the vestibule; and each evening he came away knowing that she had not been in the house. It was a habit that yielded him a sort of satisfaction along with the guilty excitement of his search; for he too loved music, and nothing gave him so much peace while its magic endured. * * * * * One night as he entered, hurrying through the brilliant crowd, he felt a touch on his arm. Flooded with an incredible certainty at the touch, he turned. It was she: so much more radiant in the absence of grief and anxiety, in the fact that she was smiling, and in the allurement of evening dress, that he could not speak. She, too, breathed a little quickly, and there was a light of daring in her eyes and cheeks as she greeted him. Her words were few. "I wouldn't miss a note of _Tristan_," she said, "nor must you. Come and see me in the interval." She gave him the number of the box. CHAPTER XII ERUPTION
