"Keep her going, George," said Roger as quietly as was his wont. "Our hope's in speed now, and dodging, till the Bella Cuba takes a part in this game."

As if the calling on her name had conjured her like a spirit from the "vasty deep," the graceful form of the yacht came into sight. George, tingling with the joyous lust of the battle, could not resist a hurrah; but his shout was deadened by the din of another shot, and then an answering roar from the Bella Cuba. One of those cannon of hers had "paid for its keep" at last. Now the yacht, and every one on board her—to say nothing of the three who wished to be on board—were in for a penny, in for a pound.

The act just committed was an offense against law and justice (not always the same) and joined hands with piracy. To be caught meant punishment the most severe for all, possibly even international complications. If the French prison-boat sunk the yacht and the launch, and drowned every soul concerned in this mad adventure, she would be within her rights, and the fugitives knew it well. The Bella Cuba had flung the red rag into the face of the bull, and Roger Broom and George Trent thought they saw Virginia's hand in the unhesitating challenge. Captain Gorst might have thought twice before assuring himself that the time had come to obey orders given in case of dire necessity; but once would be enough for Virginia.

"She's given herself away!" laughed George, keeping the launch between the lagoon and an irregular line of dark horns which, rising just above the shining surface of the water, marked a group of coral reefs. "There won't be much doubt in Johnny Crapaud's mind now as to what part that tidy little craft's cast to play in this show, eh? Hello-o!"

Another blaze and a following roar drew the exclamation; but before George had had time to draw breath after it, he and Roger and Maxime were all three in the water. The ball from the little cannon of the prison-boat had done its work better this time, striking the electric launch on her nose and shattering her to pieces.

George Trent was a brave man, but his first thought was "Sharks!" and the horror of it caught his throat with a sensation of nausea. The instinct of self-preservation is strong in all healthy men, and, though an instant later he was ashamed on realizing it, the fear that thrilled him was for himself. He expected, as his momentarily scattered senses told him what had happened and where he was, to feel huge teeth, sharp as scythes, meet round his thigh and cut off a leg as cleanly as a surgeon's knife.

While he still quivered with this living horror, he remembered that the danger was Roger's and Maxime's as well as his, and manhood and unselfishness came back. He forgot himself in his fear for them, more especially for Maxime—poor Maxime, who had suffered so much that it would be hard indeed if he were to meet a ghastly death in the very act of achieving safety and freedom. Madeleine's beautiful, tragic face rose, clear as a star, before his eyes, and he knew that it would be reward enough for him if he could give his life for the brother she loved so well. If she should say afterward, "Poor fellow, he died that you might live, Maxime," he felt that the words and the gratitude in the girl's heart would warm him even, if his grave were to be under these dark waters at the other end of the world.

He had gone down at first, and a hundred thoughts seemed to have spun themselves in his head by the time he rose to the surface. Shaking the water out of his eyes, he looked anxiously round for Roger and Maxime. They were nowhere to be seen, and a pang shot through George Trent's breast like a dagger of ice. What if one or both of them had already met the terrible fate which he had pictured for himself?

His whole soul was so concentrated upon this fear that for a few seconds he was deaf and blind to everything outside; but suddenly he realized that the firing between the yacht and the Government boat was still going on, a further cannonade which woke strange echoes over the water.

"Roger—Dalahaide!" he called. No answer came, but, as his eyes strained through the haze of moonlight, a dark dot appeared on the bright mirror of the sea, moving fast, and a cry was raised which, though not loud, carried clearly, and seemed to George Trent the most terrible he had ever heard:
