He laughed. "I can't tell," he said, "of course, because I can't see any of her crew; but I know the boat, and Ogilvie should be in it."
"But how can you know the boat? One motor-boat looks much like another at that distance—to me."
"I don't know how, but I know the boat. How do you know your friends as far off as you can see them?"
And Eve laughed, and she went on marvelling. But Miss Radnor, who had disappeared so quietly, had not reappeared, and Mrs. Fergus seemed to be getting anxious. She looked at her husband.
"Dick," she began, "I wish Elizabeth wouldn't stay under so long. Where—"
At that moment a red cap bobbed up on the surface of the glassy water almost at the side of the yacht, and Miss Radnor laughed up at us. She swam to a boat swinging at the boom, climbed in and up the little rope ladder to the boom, and so on deck.
"Sorry," she called, "to drip on your deck, but I want to dive."
And she went up the rigging as far as she could go, which was not far—was not far enough, it seemed.
"You should have the mainsail up," she said. "I could go up on the rings. It is such a disappointment! I wanted to try it from the spreaders."
