"Is that all?" asked her father. "Of course a man's life cannot be as unsullied as a girl's. One must sow one's wild oats. Margaret will not think you unworthy; not she. She knows nothing of the world, absolutely nothing. It is a pure heart and a true one; and it is yours, if I'm not an old blunderhead. She loves you, and she has never given a thought to any other man. Think of that, Sidney! If you marry her I shall die happy."

But once more a silence fell between them like a cloud. For a minute or two Sidney felt an unutterable joy in the thought that Margaret loved him. All at once the utter loneliness of all his future years, if he must give her up, flashed across him. For when Colonel Cleveland died this friendly and intimate intercourse between them must cease; and Margaret would in time become the wife of some other man. The mingled sweetness and bitterness of this moment were almost more than he could bear. Margaret loved him, and it was an exquisite happiness to know it; but behind her beloved image stood another forbidding his happiness. It was more than seven years since he had deserted Sophy; and he had been content to let the time slip away, uncertain of her fate, and dreading to learn that she was still alive. Why had he been such a coward? What could he now say to Margaret's father? To have that which he most longed for pressed upon him, and yet be unable to accept it, was torture to him. No path seemed open to him; it seemed impossible to confess the truth. For in the clear light shining upon his conduct at this moment he saw how dastardly and selfish it had been. He had forsaken a young and friendless girl in a moment of passion, and had left her in a strange land, far from her own people, when the hour of woman's sharpest peril was at hand. It was a horrible thing to have done; one which no true woman could forgive. And how would Margaret look upon him if she ever knew the truth?

"I love Margaret," he said at last in a faltering voice, "but I cannot speak of it yet; and I cannot think of marriage for a while. Trust me, Colonel Cleveland. Margaret shall always find a friend in me; and if ever I can ask her to be my wife, it will be the happiest day in my life to me."

"I regret I mentioned it to you," answered Colonel Cleveland stiffly.

Sidney left him sooner than usual, and rode slowly back over the Common, as he had done last autumn, on the night when he first saw Margaret. But it was a month earlier in the year; and the leaves still hung thick upon the trees, which looked black and dense against the sky. The birds had not yet forsaken the Common in search after winter quarters, and a drowsy twitter from the low bushes answered the sound of his horse's hoofs as he rode along. A soft, westerly wind was blowing, and bringing with it the fresh air from all the open lands lying west of London. As he looked round at the house he saw Margaret standing on the balcony belonging to her window, a tall, slim, graceful figure, dressed in white, with the pale moonlight falling on her. His heart ached with a deep and heavy pain.

"God bless her and keep her from sorrow," he said to himself.

If it was true that Margaret loved him, a bitter sorrow lay before her, one of his making. He had done wrong in going so frequently to see her, and in making so much of her friendship. It had been an unconfessed pleasure to them both; but he ought to have foreseen for her, as well as for himself, what danger lay in its indulgence. Margaret was not brought into contact with any other men, excepting George, who was just married; and Sidney was obliged to own to himself that he had done all he could to win her affection. But he repented it now. Margaret's love could only bring her sorrow.

He could have gone back and confessed to her his boyish folly, if it had been mere folly. Had Sophy died, he could have told Margaret all about it. But what he could not own was that for seven years he had left himself in absolute ignorance of her fate. No true woman could forgive a crime like that. It was a dastardly crime, he said to himself. He repented of it bitterly; but for some sins there seems no place of repentance, though it is sought carefully, with tears.

Sidney passed the night in close and troubled thought. At last the time had come when he must turn back to the moment when he abandoned his young wife to her fate; and he must trace out what that fate had been. He must at least ascertain whether she was living or dead. What he would do if she was living he need not yet decide. It was impossible for him to undertake this search himself; a search which ought to have been made years before, and without which it was hopeless to think of Margaret as his wife. But he had an agent at hand to whom he could intrust this difficult and delicate mission. There was a clerk in his office who had been in his uncle's employ for over thirty-five years, to whom had been intrusted several important investigations, and who had given many proofs of his ability and probity. He would send Trevor to the Ampezzo Valley, where he had left Sophy seven years ago; giving to him such directions and indications as were in his power for tracing her movements after his desertion of her.

He arranged and wrote some notes for Trevor's guidance, with shrewd and clear-sighted skill, careful not to incriminate himself more than was absolutely necessary; and yet finding himself compelled to admit more than it was wise for any man save himself to know. He was conscious that he was placing too close a confidence in his clerk's hands, and might have to pay heavily for it in years to come. But he must run the risk; there was no alternative. He could not carry through these investigations in person; and the time had come when he must learn the fate of his young wife.
