The next was a day of anxious tension. The long sinuous snakeback of the shell-ridge showed black all its length at the bottom of the afternoon ebb, but contrary to their expectations nothing moved in the camp of the enemy. It was evident that they were waiting for the early morning. The water would be at its lowest shortly after three, when the rush could be made with sufficient light to see. This was the more necessary as there were many quicksands to either side and in one or two places the ridge was not quite continuous. The winter storms altered it, sometimes by many feet, leaving isolated humps and mounds with quicksands about them, which might easily trap the unwary. The enemy was evidently not going to take any risks.
After Whitefoot's death Stair had perforce to tell everything to Patsy. It was wonderful how it strengthened and reaffirmed her.
"Why did you not tell me?" she said. "Why did you take counsel with everybody but me?"
"I did not," said Stair, smiling at her. "It was Eben who discovered everything, and then came and asked me. I thought that there might be nothing in it, and it was not till I was perfectly sure, that I saw the necessity of disturbing you."
"You will never treat me as a child again?" she had her hands on his sleeve now, and was looking up into his face.
"No," he said, "I know too well who carried me off here, breaking prisons to get me—and has not known what to do with me since!"
"Oh, don't say that, Stair. I love you very dearly—more than I thought possible."
He gazed at her for a moment, saw that his time had not yet come, and then gently patted her cheek, so gently that she did not resent the caress. All that day they watched the curving trenches from a little angle of the tower from which a rifle could be brought to bear on the shell causeway. That afternoon seemed everlasting. It was a clear, still twilight, and they did not dine till nearly midnight. If the Good Intent were to send a boat it would be to the back of the island which the tide never left. Indeed, Leg-o'-Mutton Bay was the only spot where a boat could land. There was always deep water there.
At one o'clock Stair saw a ship's lights very far away. It was very doubtful, even supposing that she were the Good Intent, that she could be there in time. But in the crucial hours, Eben the Spy proved himself wonderfully helpful and encouraging. His Uncle Kennedy never promised without keeping his promise. There might be a bit of a skirmish as the men were coming over, but he could warrant that they would be safe on board along with Captain Penman before ever a soldier set his foot on the island. On this he would pledge his life.
