And so Jack found her when he came home. The stillness of the whole place showed him the children must be absent, and a vague alarm seized upon him. His fears for Estelle were easily roused. Yet fear or danger seemed very far from that bright, cheerful kitchen. Putting down the armful of things he was carrying, he gazed tenderly at his mother as he warmed his fingers over the genial flames. He could not bear to awaken her, and surely it was not necessary. She would never be sleeping so peacefully unless their little girl were safe. Yet something tugged at his heart, making him stir uneasily. The movement, slight though it was, awoke his mother. She opened her eyes, gazed at him a few moments sleepily, and sat up with a laughing remark about her own laziness.

'Where's Missy?' asked Jack, as soon as he had answered all her questions about his fishing and the luck he had had.

'They were playing on the beach,' she said, putting her cap straight before taking up her knitting. 'M. Julien came to join her in watching for your return. Did you not see them on your way up? If they are not there, they must be in the caves,' she added hastily, seeing her son's face change, and instantly becoming a prey to all sorts of fears. 'They must be there if they are not on the beach,' she repeated, turning pale.

Jack only stared at her, his eyes wild, unable to believe the extent of his mother's trust in so young a boy as Julien Matou. Recovering himself quickly he rushed off without a word to his own room, and presently reappeared with a long rope in his hand.

'What do you think has happened?' cried Mrs. Wright, rising quickly from her chair in her fright at his face and manner.

'The tide!' exclaimed Jack, seizing a pair of grappling irons he had laid upon the bench a few minutes before. 'If they are in the caves there is but one way of saving them—the Treasure Cave. Pray that I may be in time!'

He was gone almost before he had ceased speaking, his light step and long limbs carrying him swiftly down the sandy path, and round the corner of the spur of cliff. The tide had already reached the gorge. It must be well into the caverns then. With firm feet he scrambled along the rocks wherever they could help him, or took to the water when he thought the waves would serve him better. As he drew nearer, he found there was still time to gain the entrance to the outer cave before it was submerged. With the tide in his favour, he managed this with ease. His chief troubles would be with the strong under-tow and numerous currents among the rocks.

Half swimming, half clambering, he made his way to the Cave of the Silver Sand. Here the daylight was in his favour, but the whirl of waters was dangerous and strong. Anybody who did not know the rocks as well as Jack must have been sucked under to his destruction. Clinging to the rocks, he made his way towards the Rift. Awaiting his chance, he swam through this on the crest of a wave, and beheld the feeble light of one remaining candle glimmering in front of him.

With anxious eyes he surveyed the darkness around, and then the objects moving within the radius of that faint spark. Steadying himself against the rocks, he was about to plunge again into the water, in order to reach that point of light, when a heavy body was thrown against him.

Instinctively he grasped it, the surge of the water and the weight of the inanimate form making him almost lose his hold. A few moments more and his burden would have been sucked into the Rift, where his fate would have been sealed indeed. It did not take Jack long to discover it was Julien he held in his arms: Julien senseless, cold, drowning!
