But in his excitement Vine did not heed this, going on and on regardless of the difficulties, and Louise unmurmuringly walked or at times climbed along, till they were right out at the extreme point where, some feet below them, the water rushed and gurgled in and out of the crevices with terrible gasping noises, such as might be made by hungry sea-monsters thronging round to seize them if either of them should make a slip.

Here Vine paused again and again to watch the lantern in the lugger, and listen for the rattle of oars in the rowlocks, the oars of the boat conveying his son to the men who would at once hoist the sails and bear him away to a place of safety. But the dim light of the horn lantern rose and fell, there was no rattle of oars, not even the murmur of a voice; nothing but the sucking, gasping noises at their feet, as the tide swirled by like the race of waters from some huge mill.

Louise clung more tightly to her father’s arm, as he stood again and again where she had often from a rock behind watched her uncle deftly throwing out his line to capture some silvery-sided bass or a mackerel, glowing with all the glories of the sea at sunrise.

“If he should slip,” she said to herself, as she tightened her grasp of her father’s thin arm, “if he should slip!” and she shuddered as she gazed down into the deep, black rushing water, where the star reflections were all broken up and sparkled deep down as if the current were charged with gold dust, swirling and eddying by. Then she started as her father spoke aloud to himself.

“No, no, no!” he murmured. Then sharply, “Come, let us get back.”

Louise crept along by him in silence, her heart giving one violent leap, as Vine slipped once on the spray-wet rocks, but recovered himself and went on without a word. Again and again, she suffered that terrible catching of the breath, as her father slipped, caught his foot in some inequality, or would, but for her guidance, have stumbled over some projecting rock post and been thrown into the harbour. For as he walked on, his eyes were constantly searching the dark surface as he listened intently for some token of the escaping man.

But all was still as they neared the town, still with the silence of death. No one could have told that there were watchers by the ferry, where a rough boat was used for crossing from side to side of the harbour; that two boats were waiting, and that Duncan Leslie was patrolling the short arm of granite masonry that ran down to the tower-like building were the harbour lantern burned.

“Hist!” whispered Louise, for there was a step some little distance away, but it ceased, and as she looked in its direction, the cliffs seemed to tower up behind the town till a black, jagged ridge cut the starry sky.

“Let’s go back,” said her father, huskily. “I fancied I heard a boat stealing along the harbour; we cannot see the lugger light from here.”

“George!” came from out of the darkness ahead.
