His grasp tightened on flesh, fingers closed about thin wrists. There was a yell of astonishment and fear from the stranger as the Terran jerked him from his perch to the ledge. Ross had his opponent flattened under him before he realized that the other had offered no struggle, but lay still.
"What is it?" Karara's torch beam caught them both. Ross looked down into a thin brown face not too different from his own. The wide-set eyes were closed, and the mouth gaped open. Though he believed the Hawaikan unconscious, Ross still kept hold on those wrists as he moved from the sprawled body. With the girl's aid he used a length of kelp to secure the captive.
The stranger wore a garment of glistening skintight material which covered body, legs, and feet, but left his lanky arms bare. A belt about his waist had loops for a number of objects, among them a hook-pointed knife which Ross prudently removed.
"Why, he is only a boy," Karara said. "Where did he come from, Ross?"
The Terran pointed to the wall crevice. "He was up there, watching you."
Her eyes were wide and round. "Why?"
Ross dragged his prisoner back against the wall of the cave. After witnessing the fate of those who had swum ashore from the wreck, he did not like to think what motive might have brought the Hawaikan here. Again Karara's thoughts must have matched his, for she added:
"But he did not even draw his knife. What are you going to do with him, Ross?"
That problem already occupied the Terran. The wisest move undoubtedly was to kill the native out of hand. But such ruthlessness was more than he could stomach. And if he could learn anything from the stranger—gain some knowledge of this new world and its ways—he would be twice winner. Why, this encounter might even lead to Ashe!
"Ross ... his leg. See?" The girl pointed.
The tight fit of the alien's clothing made the defect clear; the right leg of the stranger was shrunken and twisted. He was a cripple.
"What of it?" Ross demanded sharply. This was no time for an appeal to the sympathies.
But Karara did not urge any modification of the bonds as he half feared she would. Instead, she sat back cross-legged, an odd, withdrawn expression making her seem remote though he could have put out his hand to touch her.
"His lameness—it could be a bridge," she observed, to Ross's mystification.
"A bridge—what do you mean?"
The girl shook her head. "This is only a feeling, not a true thought. But also it is important. Look, I think he is waking."
The lids above those large eyes were fluttering. Then with a shake of the head, the Hawaikan blinked up at them. Blank bewilderment was all Ross could read in the stranger's expression until the alien saw Karara. Then a flood of clicking speech poured from his lips.
He seemed utterly astounded when they made no answer. And the fluency of his first outburst took on a pleading note, while the expectancy of his first greeting faded away.
Karara spoke to Ross. "He is becoming afraid, very much afraid. At first, I think, he was pleased ... happy."
"But why?"
The girl shook her head. "I do not know; I can only feel. Wait!" Her hand rose in imperious command. She did not rise to her feet, but crawled on hands and knees to the edge of the ledge. Both dolphins were there, raising their heads well out of the water, their actions expressing unusual excitement.
"Ross!" Karara's voice rang loudly. "Ross, they can understand him! Tino-rau and Taua can understand him!"
"You mean, they understand this language?" Ross found that fantastic, awesome as the abilities of the dolphins were.
"No, his mind. It's his mind, Ross. Somehow he thinks in patterns they can pick up and read! They do that, you know, with a few of us, but not in the same way. This is more direct, clearer! They're so excited!"
Ross glanced at the prisoner. The alien had wriggled about, striving to raise his head against the wall as a support. His captor pulled the Hawaikan into a sitting position, but the native accepted that aid almost as if he were not even aware of Ross's hands on his body. He stared with a kind of horrified disbelief at the bobbing dolphin heads.
"He is afraid," Karara reported. "He has never known such communication before."
"Can they ask him questions?" demanded Ross. If this odd mental tie between Terran dolphin and Hawaikan did exist, then there was a chance to learn about this world.
"They can try. Now he only knows fear, and they must break through that."
What followed was the most unusual four-sided conversation Ross could have ever imagined. He put a question to Karara, who relayed it to the dolphins. In turn, they asked it mentally of the Hawaikan and conveyed his answer back via the same route.
It took some time to allay the fears of the stranger. But at last the Hawaikan entered wholeheartedly into the exchange.
"He is the son of the lord ruling the castle above." Karara produced the first rational and complete answer. "But for some reason he is not accepted by his own kind. Perhaps," she added on her own, "it is because he is crippled. The sea is his home, as he expresses it, and he believes me to be some mythical being out of it. He saw me swimming, masked, and with the dolphins, and he is sure I change shape at will."
She hesitated. "Ross, I get something odd here. He does know, or thinks he knows, creatures who can appear and disappear at will. And he is afraid of their powers."
"Gods and goddesses—perfectly natural."
Karara shook her head. "No, this is more concrete than a religious belief."
Ross had a sudden inspiration. Hurriedly he described the cloaked figure who had driven the castle people from the piles of salvage. "Ask him about that one."
She relayed the question. Ross saw the prisoner's head jerk around. The Hawaikan looked from Karara to her companion, a shade of speculation in his expression.
"He wants to know why you ask about the Foanna? Surely you must well know what manner of beings they are."
"Listen—" Ross was sure now that he had made a real discovery, though its importance he could not guess, "tell him we come from where there are no Foanna. That we have powers and must know of their powers."
If he could only carry on this interrogation straight and not have to depend upon a double translation! And could he even be sure his questions reached the alien undistorted?
Wearily Ross sat back on his heels. Then he glanced at Karara with a twinge of concern. If he was tired by their roundabout communication, she must be doubly so. There was a droop to her shoulders, and her last reply had come in a voice hoarse with fatigue. Abruptly he started up.
"That's enough—for now."
Which was true. He had to have time for evaluation, to adjust to what they had learned during the steady stream of questions passed back and forth. And in that moment he was conscious of his hunger, just as his voice was paper dry from lack of drink. The canister of supplies he had left by the cave entrance ...
"We need food and drink." He fumbled with his mask, but Karara motioned him back from the water.
"Taua brings ... Wait!"
The dolphin trailed the net of containers to them. Ross unscrewed one, pulled out a bulb of fresh water. A second box yielded the dry wafers of emergency rations.
Then, after a moment's hesitation, Ross crossed to the prisoner, cut his wrist bonds, and pressed both a bulb and a wafer into his hold. The Hawaikan watched the Terrans eat before he bit into the wafer, chewing it with vigor, turning the bulb around in his fingers with alert interest before he sucked at its contents.
As Ross chewed and swallowed, mechanically and certainly with no relish, he fitted one fact to another to make a picture of this Hawaikan time period in which they were now marooned. Of course, his picture was based on facts they had learned from their captive. Perhaps he had purposely misled them or fogged some essentials. But could he have done that in a mental contact? Ross would simply have to accept everything with a certain amount of cautious skepticism.
