He turned back sharply. There had been something in Ruth's voice, something so entirely foreign to her usual manner, that he was startled. It was almost a cry of despair. She had made an impulsive movement towards him, but in another minute she was mistress of herself once more.

"Till next month," she said cheerfully.

Two minutes later the train started.

Ruth sat very still, biting her under lip and trying hard to keep the unaccustomed tears from her eyes. She felt a sudden sense of horrible desolation. There was a wild longing upon her to jump out of the train and to go back before it was too late. She, so calm, so self-assured, for the first time in her life felt like a leaf swept by the wind. If her father knew—what would he say?

Madness! Yes, just that, madness! For the first time in her life she was swept away by emotion, swept away to the point of doing a thing which even she knew to be incredibly foolish and reckless. She was enough Van Aldin's daughter to realize her own folly, and level headed enough to condemn her own action. But she was his daughter in another sense also. She had that same iron determination that would have what it wanted, and once it had made up its mind would not be balked. From her cradle she had been self-willed; the very circumstances of her life had developed that self-will in her. It drove her now remorselessly. Well, the die was cast. She must go through with it now.

She looked up, and her eyes met those of the woman sitting opposite. She had a sudden fancy that in some way this other woman had read her mind. She saw in those grey eyes understanding and—yes—compassion.

It was only a fleeting impression. The faces of both women hardened to well-bred impassiveness. Mrs. Kettering took up a magazine, and Katherine Grey looked out of the window and watched a seemingly endless vista of depressing streets and suburban houses.

Ruth found an increasing difficulty in fixing her mind on the printed page in front of her. In spite of herself, a thousand apprehensions preyed on her mind. What a fool she had been! What a fool she was! Like all cool and self-sufficient people, when she did lose her self-control she lost it thoroughly. It was too late.... Was it too late? Oh, for some one to speak to, for some one to advise her. She had never before had such a wish; she would have scorned the idea of relying on any judgment other than her own, but now—what was the matter with her? Panic. Yes, that would describe it best—panic. She, Ruth Kettering, was completely and utterly panic stricken.

She stole a covert glance at the figure opposite. If only she knew some one like that, some nice, cool, calm, sympathetic creature. That was the sort of person one could talk to. But you can't, of course, confide in a stranger. And Ruth smiled to herself a little at the idea. She picked up the magazine again. Really she must control herself. After all, she had thought all this out. She had decided of her own free will. What happiness had she ever had in her life up to now? She said to herself restlessly: "Why shouldn't I be happy? No one will ever know."

It seemed no time before Dover was reached. Ruth was a good sailor. She disliked the cold, and was glad to reach the shelter of the private cabin she had telegraphed for. Although she would not have admitted the fact, Ruth was in some ways superstitious. She was of the order of people to whom coincidence appeals. After disembarking at Calais and settling herself down with her maid in her double compartment in the Blue Train, she went along to the luncheon car. It was with a little shock of surprise that she found herself set down to a small table with, opposite her, the same woman who had been her vis-à-vis in the Pullman. A faint smile came to the lips of both women.
