This parting speech sent Laurie forth in a renewed tempest of rage and indignation. He had meant to return up-stairs after his visit to old Welby, but that was now impossible. He had let himself out, and closed the door sharply behind him, before old Forrester could make his appearance. Daylight by this time was beginning to fail, and the lamps were being lit along the street, twinkling across the Square through the smoky trees, which were swelling with the fulness of spring. The look of the outside world as he came thus suddenly into it,--the tall, glimmering houses,--the lamps like candies in the pale, waning daylight,--the trees all bristling with half-opened leaves, and the sky, leaden yet light, with its remoteness, and colourless serenity, looking down upon all, never went out of Laurie’s mind. He forgot all his displeasure at her absence, all his wondering where she was. He did not even look if she might be coming, or remember that he might meet her suddenly face to face so near her own door. His mind was too full of her idea to remember herself, if we may say so. He went round and round the Square without any particular sense of where he was going, and then took the first street, any street,--what did it matter?--and got out into a crowded thoroughfare, where lights were gleaming, and men hurrying, and every sound and stir of life. It was a long time before he could even make out his own thoughts, what they were. All was dimness and chaos and commotion, like the scene around at first; lights gleaming, cries coming out of the obscurity,--a tumult he could not comprehend. Then by degrees the clouds rolled off, each to its own corner; the foreground cleared, the central figure reappeared. What was it? Laurie stood still for a moment, and looked himself, as it were, in the face, aghast. He had not so much as suspected it till now. She had been his friend; nothing so tender, nothing so near, had ever been in his life; yet he had not dreamed what the truth was until old Welby, with his detestable suggestion, had thrust it thus unveiled in his face.
