"Ah, pardon me!" he said. "But why did you wait?"
"Of course I waited," said Chris. "I said I would."
"And you were not afraid? No?"
He was standing close to her now, and Cinders was wriggling to reach and welcome him.
"Yes, a little," Chris admitted. "That's why I whistled. But it's all right now. Do let us get out."
"Ah!" he said. "But I fear—"
"What?" she asked, with sudden misgiving.
He hesitated a moment, then, "The tide," he said.
"Bertie!" For the first time Chris's bravely sustained courage broke down. She thrust out a clinging hand and clutched his arm. "Are we going to be drowned—here—in the dark?" she said, gasping.
"No, no, no!" His reply was instant and reassuring. He took her hand and held it. "It is not that. The water will not reach us. It is only that we cannot return until the tide permit."
