She wrote to him before she went to bed. It was a duty of civility to answer him, though she felt herself under no obligation to reply to his numerous questions. On the contrary, she said nothing at all about them, but she gave him her impressions of Lucerne and told him that Aunt Rachel had taken cold, but was now quite well, a piece of information which, though satisfactory in its way, was not calculated to affect her correspondent's happiness in any marked degree. 'It would be nice to see each other again,' she said at the end, with which mild sentiment she signed herself 'sincerely' his.

The only odd thing about it all was that when the letter was finished she had not the slightest idea where to send it, a fact which had not crossed her mind when she had unscrewed her travelling inkstand, but which sufficiently proved that she had acted under an impulse of some sort. She said to herself that it did not matter, but she was disappointed, and the smile faded from her face for a little while.

When she was asleep it came back in the dark and lingered on her lips all night, waning and waxing with her maiden dreams.

Her eighteenth birthday had been a good day in her life, after all. There are few indeed who fall asleep happily when the first illusion has gone down into darkness with the evening sun.

CHAPTER XI

Helen Harmon went out alone to mail her letter. She would not have done such a thing in any great city of Europe, but there is a sense of safety in the dull, impersonal atmosphere of Lucerne, and it was a relief to her to be out in the open air alone; it would be a still greater relief to have dropped the letter into the mysterious slit which is the first stage on the road to everywhere.

No one ever thinks of the straight little cut, with its metal cover, as being at all tragical. And yet it is as tragic as the jaws of death, in its way. Many a man and woman has stood before it with a letter and hesitated; and every one has, at some time or other, felt the sharp twist at the heart, which is the wrench of the irrevocable, when the envelope has just slipped away into darkness. The words cannot be unwritten any more, after that, nor burned, nor taken back. A telegram may contradict them, or explain them, or ask pardon for them, but the message will inevitably be read, and do its work of peace or war, of challenge or forgiveness, of cruelty, or kindness, or indifference.

Helen did not mean to hesitate, for she hastened towards the moment of looking back upon a deed now hard to do. It was not far to the post office, either, and the thing could soon be done. Yet in her brain there was a surging of uncertainties and a whirling of purposes, in the midst of which she clung hard to her determination, though it should cost ever so dear to carry it out. She had not half thought of all the consequences yet, nor of all it must mean to her to be separated from her son. The results of her action sprang up now, like sudden dangers, and tried to frighten her from her purpose, tried to gain time against her to show themselves, tried to terrify her back to inaction and doubt. Something asked her roughly whence she had got the conviction that she was doing right at all. Another something, more subtle, whispered that she was sacrificing Archie for the sake of her own morbid conscience, and making herself a martyr's crown, not of her own sufferings only, but of her son's loss in losing her. It told her that the letter she held in her hand was a mistake, but not irrevocable until it should have slipped into the dark entrance of the road to everywhere.

She had still a dozen steps to make before reaching the big white building that stands across the corner of the street, and she was hurrying on, lest she should not reach the door in time. Then she almost ran against Colonel Wimpole, walking slowly along the pavement where there was a half shadow. Both stopped short, and looked at each other in surprise. He saw the letter in her hand, and guessed that she had written to her husband.

"I was only going to the post office," she said, half apologetically, for she thought that he must wonder why she had come out alone at such an hour.
