James considered the case. "But even suppose we are within a mile or two, say, of the shore, could you ever swim two miles in this heavy sea?"

"It is growing calmer every minute. See, I can do very well, even swimming alone. It must be near morning, too, and that's always, a good thing." There was the shadow of a laugh in her voice.

"Morning? That depends," growled Jim. He was being soothed in spite of himself, and in spite of the direfulness of their situation. But bad as the situation was, and would be in any case, he could not deny the proposition that morning and daylight would make it better.

"But aren't you tired already? You must be." James turned closer to her, trying to read her face. "It was a long night of anxiety, even before we left the boat. Weren't you frightened?"

"Yes, of course; but I've been getting used to frights of late, if one can get used to them." Again there was the laugh in her voice, under all its seriousness, even when she added: "I'm not sure that this isn't safer than being on board the Jeanne D'Arc, after all!"

It was characteristic of James that he forebore to take advantage of the opening this speech offered. The possible reason of her abduction, her treatment on board the yacht, her relation to Monsieur Chatelard—it was all a mystery, but he could not, at that moment, seek to solve it. Her remark remained unanswered for a little time; at last he said: "Then the Jeanne D'Arc must have been pretty bad."

"It was," she said simply.

Jim wondered whether she knew more about the crime of which she was the victim than he knew, or if she had discovered aught concerning it while she was a prisoner on the yacht. Granting that her person was so valuable that a man of Monsieur Chatelard's caliber would commit a crime to get possession of it, why should he have abandoned her when there was plainly some chance of safety in the boats? He could not conceive of Monsieur Chatelard's risking his neck in an affair of gallantry; cupidity alone would account for his part in the drama. James went over and over the situation, as far as he understood it, but he did none of his thinking aloud. It flashed on his mind that Miss Redmond must already have separated him, in her thoughts, from the other people on the yacht; though perhaps her trust was instinctive, arising from her own need of help. How could she know that he had risked his neck twice, now, to follow the Vision?

Swimming slowly, with Agatha's hand at times on his shoulder, James turned his mind sharply to a consideration of their present position. They had been alternately swimming and floating, hoping to come upon the yacht. The darkness of the night was penetrable, so that they could see a fairly large circle of water about them, but there was no shadow of the Jeanne D'Arc. Save for the running surge of the waters, all was silence. The pale forerunners of dawn had appeared. Their swim after the boats of the Jeanne D'Arc had warmed their blood, so that for a while they were not conscious of the chill of the water. But as the minutes lengthened, one by one, fatigue and cold numbed their bodies. It was a test of endurance for a strong man; as for the girl, Jim wondered at her strength and courage. She swam superbly, with unhurried, steady strokes. If she grew chatteringly cold, she would start into a vigorous swim, shoulder to shoulder with James. If she lost her breath with the hard exercise, she would take his hand, "so as not to lose you," she would say, and rest on the breast of the waves. The wind dropped and the sea grew quiet, so that they were no more cruelly buffeted, but rocked up and down on its heaving bosom.

Once, while they were "resting" on the water, Agatha broke a long silence with, "I wonder—" but did not at once say what she wondered at. Jim said nothing, but she knew he was waiting and listening.
