Part 22

"I don't know El Morro," said Roddy.

"You have probably seen it," Inez explained, "without knowing it was a fort. It's in ruins now. Have you noticed," she asked, "to the right of the town, a little hill that overlooks the harbor? It is just above the plain where the cattle are corralled until they are shipped to Cuba. Well, the ruins of El Morro are on top of that hill. It is about a quarter of a mile from San Carlos, so we know that is the length of the tunnel. Pedro tells me, for a part of the way it runs under the water of the harbor. It was cut through the solid rock by the prisoners at San Carlos."

"There must be a lot of people," objected Roddy, "who know of it."

"Fifty years ago they knew of it," returned Inez eagerly, "but, remember, for half a century it has virtually ceased to exist. And besides, to my people there is nothing unusual in such a tunnel. You will find them connected with every fort the Spaniards built along this coast, and in Cuba, and on the Isthmus of Panama. All along the Spanish Main, wherever there is more than one fort, you will find them linked together by tunnels. They were intended to protect the soldiers from the fire of the enemy while they were passing from one position to another."

The young people had been standing ankle-deep in the soft, moist sand. Now the girl moved toward her pony, but Roddy still stood looking out to sea. He appeared to have entirely forgotten that Inez was present, and to be intently regarding the waves that surged against the rocks, and burst into glittering walls of foam. At last, with a serious countenance, he came toward her.

"I shall tell the authorities at Porto Cabello," he said, "that they ought to build a light-house on El Morro. At any rate, I will ask permission to make a survey. As they don't intend to pay father for any of his light-houses, they are not likely to object. And as I don't intend to build one, father can't object. He will attribute my offer to mistaken zeal on behalf of the company. And he will consider it another evidence of the fact that I don't understand his business. As soon as I find out anything definite I will let you know. And, by the way," he asked, "how am I to let you know?"

Inez gave him the address of a fellow-exile from Venezuela, living in Willemstad, who was in secret communication with Pedro. Through this man letters would reach her safely.

She turned to him in farewell, and held out her hand.

"You must be very careful," she said.

"Trust me!" answered Roddy heartily. "I promise you I'll be as mysterious a double-dealer as any Venezuelan that ever plotted a plot. I admit," he went on, "that when I came down here I was the frank, wide-eyed child, but, I assure you, I've reformed. Your people have made me a real Metternich, a genuine Machiavelli. Compared to me now, a Japanese business man is as honest and truth-loving as Mrs. Wiggs of the Cabbage Patch."

With a grin, Roddy invited the girl to sympathize with his effort to conceal the seriousness of their undertaking, but she regarded him doubtfully, and frowned. In his heart Roddy felt sorry for her. It hurt him to think that any one so charming could not accept his theory, that the only way to treat a serious matter was with flippancy. But the girl undeceived him.

"You don't understand me," she said quietly. "I didn't mean to be careful to protect our interests. I meant you to be careful of yourself. If anything were to happen to you through this--" She hesitated and looked away from him toward the sea. "Do you imagine," she demanded, "that it is easy for me to ask what I am asking of you? I know I have no right to do it. I know the only possible excuse for me is that I am not asking it for myself, but for my father--although, of course, that is asking it for myself."

"Beauty in distress," began Roddy briskly, "is the one thing----"

"That's what I mean," interrupted the girl gratefully, "the way you take it, the way you make it easier for me. Every other man I know down here would tell me he was doing it only for me, and he would hope I would believe him. But when you say you are helping beauty in distress, you are secretly frightened lest I may not have a sense of humor--and believe you. I know you are doing this because you feel deeply for my father. If I didn't know that, if I didn't feel that that were true, all this I have asked of you would be impossible. But it is possible, because I know you first tried to save my father of your own accord. Because I know now that it is your nature to wish to help others. Because you are brave, and you are generous."

But Roddy refused to be ennobled.

"It's because I'm a White Mice," he said. "My oath compels me! How would you like," he demanded, frowning, "if we turned you into an Honorary White Mouse?"

For an instant, with perplexed eyes and levelled brows, the girl regarded him fixedly. Then she smiled upon him. It was the same flashing, blinding smile which the morning before had betrayed him into her hands, bound and captive. It was a smile that passed swiftly, like a flash of sunshine over a garden of gay flowers. It brought out unsuspected, ambushed dimples. It did fascinating and wholly indefensible things to her lips. It filled her eyes with gracious, beautiful meanings. Inez raised her head challengingly.

"You think," she declared, "that I cannot be foolish, too. But I can. Let's sit down here on this rock and be quite foolish."

"I can be quite as foolish as you," Inez repeated as Roddy continued to regard her. "Some day, when this is over, when you have made it all come right, we will sit out here and pretend that we have escaped from Venezuela, that we are up North in my mother's country--in your country. We will play these are the rocks at York Harbor, and we'll be quite young and quite happy. Have you ever sat on the rocks at York Harbor," she demanded eagerly, "when the spray splashed you, and the waves tried to catch your feet?"

Roddy was regarding her in open suspicion. He retreated warily.

"York Harbor!" he murmured. "I discovered it! It is named after me. But you! I never imagined you'd been there, and I never imagined you could be anything but serious, either. It makes you quite dangerous."

"Dangerous?" murmured the girl.

"One is dangerous," said Roddy, "when one is completely charming."

The girl frowned, and her shoulders moved slightly. "You speak," she said, "like a Venezuelan."

But Roddy was in no mood to accept reproof.

"I told you," he said, "I admire the fools who rush in where angels fear to tread. There is another man I admire equally, 'the man who runs away.' It takes great courage to run away. I must do it now."

He retreated from her. His eyes were filled with a sudden, deep delight in her, and a growing wonder. The girl regarded him steadily.

"Come here," she commanded, "and say 'Good-by' to me."
