"As long as I live," answered Sidney with fervor.

It was after midnight when he rode away over the now dark and deserted Common. He was conscious that during the last few hours a crisis had come into his life; a difficulty which he had long foreseen and carefully avoided. He already loved this girl. But had he any right to love her? Was he free to win her heart? It was more than six years since he had last seen Sophy, and not a syllable of news from her had reached him. He shrank from letting down a sounding-line into the depths of these past years; it had been better to let them lie undisturbed. But why had he been such a fool as to marry Sophy Goldsmith?

The night was dark, but the sky was full of stars. Along the high roads crossing the Common lamps glimmered here and there, just tracing out the route, but leaving the open stretch of moorland as dark as if it had been hundreds of miles from any artificial light. The bushes and brushwood were black; and here and there lay small sinister-looking pools, lurking in treacherous hollows, and catching some gleam of light on their surface, which alone revealed them to the passers-by. A red gloom hung over London, throbbing as if it beat with the pulsations of the life underneath it. There were but few country sounds breaking the stillness, as there would have been on distant moorlands: but now and then the shriek of an engine and the rattling of a train jarred upon the silence; and to Sidney, when he reined in his horse and listened to it, a low roar, unlike any other sound, came from the busy and crowded streets stretching for many miles eastward. It was past midnight; and yet London was not asleep.

CHAPTER VII.
MARGARET.

Margaret Cleveland watched Sidney ride away until the darkness hid him from sight. He was to be her friend. But what perils were there in a country like England which could so fill her father's heart with dismay, and induce him to commit her welfare so solemnly to a man who was an absolute stranger to her? She was glad to have Sidney Martin as a friend; there was an attraction to her in his frank, steadfast face, which gave her great pleasure, and inspired a perfect confidence in him, the confidence of a child. But what was her father afraid of for her? To-day had been the most eventful day of her life; a crowd of emotions, mostly painful ones, had invaded the calm of her girlhood. This morning she had still been a child; to-night she was a woman.

Now that trouble had come she felt how utterly imperfect her training had been to prepare her to meet it. She knew nothing of the world. Her father had stood between her and it so completely, that when he had been brought home apparently dying, she had been unable to do anything, or to summon anyone to his aid. She did not know the name of any of his friends whom he was in the habit of meeting at his club; and if he had not recovered sufficiently to give her Sidney Martin's name and address, she would have known no one to whom she could have looked for help in any contingency.

True, they had been living abroad for some years since her mother's death, and she had felt no wish to oppose her father's plan of keeping her aloof from his somewhat distant relations, and of excluding her from all companionship except his own. She had been quite satisfied with his companionship; and her faithful and loyal nature had accorded a willing obedience to his slightest wish. He chose to treat her as a child, and she was glad to remain a child.

But to-night she did not feel sure that this mode of life had been a wise one, either for herself or him. Suddenly there had come upon her a demand for prompt decision and action, which she was unable to meet. She had been obliged to stand by and let the servants act for her. It was painful to her to feel how helpless she must have been if her father had not gained consciousness enough to whisper to her, "Write at once to Sidney Martin and ask him to come."

The doctors assured her there was no immediate danger for her father's life. Her mind, therefore, was at rest upon that point; and these other thoughts crowded irresistibly upon her serious consideration. It did not occur to her that her father purposely guarded her from making any outer use of her life; reserving all her sweetness, freshness, and girlish charm for his own pleasure merely. She had never felt herself a prisoner. Yet she knew well she did not live as other girls did; and the balls, concerts, and pleasure parties, of which her father spoke with so much scorn, probably would have had no attraction for her. But there were duties undertaken by other girls in which she had longed to share. There were children to teach, the poor to visit. "Doing good," Margaret called it, simply and vaguely. "He went about doing good," she murmured, turning away from the window, where she had lingered long after Sidney was out of sight, and looking up at a picture of our Lord, surrounded by the sick and poor. "He went about doing good," she repeated.
