“We must try. Come along.”

He hurried her forward, and, with the aid of his strong right arm, she had no difficulty in keeping pace with him. But the beach was pebbly and yielding, and before they had gone a hundred yards the consciousness broke upon them that the desired point would be ten or twelve feet under water by the time they should reach it.

“Can’t be done. We must give it up,” he said anxiously, coming to a halt. “Our only chance is to try back. The beach is not so narrow on the Battisford side. We must look sharp, too, or the point behind us will be covered.”

The treacherous waves were creeping up to the promontory he had come round. To remain where they were was hopeless, for in less than an hour the whole of the bay would be completely swept by the sea, which would be breaking against the cliffs many feet higher than their heads as they then stood.

“Now, Olive! It is our only chance.”

Breathless and panting from the pace at which she had come over the heavy yielding ground, Olive resigned herself with a shiver to be half dragged, half carried through the belt of milky surf which barred their passage round the rocky promontory, and it was all her companion could do to support her and keep his own footing amid the powerful wash and swirl of the receding waves, for he had been obliged to watch his opportunity and make a dash through between the inflowing waves, and, being knee-deep in water, with the pebbly ground beneath his feet, uncertain and shifting in the treacherous “undertow,” the wonder is that both were not carried away there and then. Yet it was only putting off the evil hour. Two minutes later and they stood within the next bay.

A quick, despairing ejaculation escaped Roland’s lips. He had miscalculated his distance, and now the strip of beach by which he had reckoned they would be able to effect their escape was a mass of great rolling breakers. To retrace their steps was impossible, even were it of any use. There was no more means of exit from this bay than from the one they had just left. They had but exchanged one death-trap for another.

Then they stood still and stole a furtive look at each other, and all hope died away within their hearts. To the mind of each there came the same thought. The man’s wild prayer and desperate vow had been heard and answered. The King of Terrors was about to exact the fulfilment of the awful bargain—and to exact it with interest—and the great, cruel sea, which alone had witnessed and registered the reckless vow, was now lending itself and its rage a willing instrument for the pitiless fulfilment of that vow.
