"Mr. Beverley and Vincent and Irene have gone inside the grotto, and they don't seem able to get out again. We can hear them shouting for help."
The party, in their British imprudence, had not brought a boatman, and they were uncertain what to do. Their own barque was too large to go through the narrow opening into the cavern, and they looked hopefully at Mr. Carson's little skiff.
"We don't know what's happened," gulped Jess.
"They went in to explore the Roman passage."
"Just by themselves."
"They've been gone such a long time," volunteered the others.
"Listen," said Peachy.
For from out the low entrance of the grotto floated a faint far-off echoing ghost of a shout.
Lorna glanced imploringly at her father. He did not hesitate for a moment. The man who had injured him was inside the cavern, perhaps in deadly danger, and he was going to risk his own life and his daughter's to save him. And risk there undoubtedly was. A breeze had arisen and agitated the surface of the water, so that the ingress was smaller than ever and more difficult to compass. When waves lashed the tideless Mediterranean even the Capri fishermen shunned entering the grotto, for they knew its perils only too well. Telling Lorna to lie flat on her back Mr. Carson took the same position, and with infinite difficulty managed to maneuver the skiff into the rocky entrance. There was barely room, for each wave bumped it against the roof, but by clinging to the chain he worked his way along and shot through into the lake within. On the right of the cavern three figures, holding a light, stood on a kind of landing-place, while a skiff drifting far off in the shadows told its own tale.
Mr. Carson rowed at once to retrieve the truant boat, and towed it back to its owners.
