Midnight was near, and the yellow lights of the town were fewer than they had been. The quay was quiet and deserted, and the Ile Nou was a black shape in the translucent glitter of the water. On the Bella Cuba all was very still, and each whisper of the little waves that lapped against the side of the yacht came distinctly to Virginia's ears.
The Countess de Mattos had not appeared at dinner, but had sent excuses, her head being much worse. But it was Virginia's opinion that, once out of sight of Noumea, the lady intended to be convalescent. Kate Gardiner also was in retirement, and had for once shown temper even to Virginia; but Dr. Grayle's report of the day was reassuring, and as Kate had had no opportunity of doing harm, even if she had wished it, she and her grievances were dismissed from Virginia's mind in these supreme moments.
Her eyes were straining after a small electric launch, which was already distant. Virginia could not look away, and still she tried to persuade herself that she could not see the little black gliding thing distinctly, because, if it was plainly visible to her, it must be so to other eyes also—if eyes on shore were waking and watching now.
Suddenly the boat disappeared behind a buttress of rock silhouetted on the silver track of the moon, and at the same instant the yacht's anchor began slowly to be hauled up.
Virginia knew what that meant. To-night's work was for Roger and George, not for her; but she had each detail of the programme at her fingers' ends—indeed, had helped to arrange it. When the launch had gone a certain distance from the Bella Cuba, on its stealthy way toward the Ile Nou, the yacht's captain—an Englishman, discreet and expert—had orders to follow slowly. The start had not been made earlier, because it was desirable that town and prison should be asleep, and the danger of discovery minimized. If the yacht were seen moving in the night suspicion would be aroused, for leaving the harbour of Noumea is a perilous undertaking except between sunrise and sunset; yet she must move, and follow the boat like one of the great black sharks swimming with grim expectancy behind her, lest the little bark should be overtaken in case of alarm and pursuit.
No explanation had been given to Captain Gorst, who neither needed nor desired any. His orders were to follow the boat, and stand in as near the Ile Nou as possible without arousing attention on shore; there to wait until the launch returned, or to approach still closer to the island, if pursuit rendered it advisable. These orders Virginia knew he would obey to the letter; and she knew also, though no word had been spoken to her on the subject, that the little cannon, which had been silent since the Bella Cuba had been a lightly armoured despatch-boat in the American-Spanish War, were ready to speak to-night, if worst came to worst.
It was that vague "worst" that troubled Virginia's soul as, almost soundlessly, the heart of the Bella Cuba began to beat, and she glided through the glimmering water. If only one could know exactly where and how to expect the blow, the thought that it might fall would be more bearable, the girl felt. But one of many things might happen to wreck their hopes; and failure now probably meant failure forever.
Maxime Dalahaide might be too ill to make the attempt to-night, or he might be watched in the act of making it. The men in the launch might miss seeing him, even if he had contrived to escape from the hospital and gain the beach. Or his flight might be discovered, and the launch only arrive near the shore in time for its occupants to see him dragged back to the old life, with all its past horrors, and many new ones added by way of punishment. Possibly the coral reefs and jagged rocks might prevent the launch getting close to shore, and Maxime would have to swim out to it. Then, there were the sharks. Virginia had already seen two or three to-day—hideous, black shapes swimming far down below the surface of the clear water—and she shuddered as she remembered the great snouts and cold, evil eyes of the man-eaters. What was that the Commandant had said in the afternoon? "The sharks are the best guardians the Ile Nou can have." Were those horrible watch-dogs of the sea on the lookout now?
At the same moment, the same thought was in the minds of Roger Broom and George Trent, as the little electric launch rounded the point of rock and lost sight of the Bella Cuba. The water, as they looked toward the Ile Nou, which must be their destination, was a flood of molten silver poured from the white-hot furnace of the full moon. They knew how black the launch must be on this sheet of radiance, how conspicuous an object to watchful eyes on shore; and though the glittering sheen destroyed the transparent effects of the water here, they guessed what gliding shapes were surely upon their track, coldly awaiting disaster.
Sitting in the boat they could not see the hospital; not a light was visible in any prison building; and they had the feeling that in any one of a dozen great masses of shadow armed surveillants might be hiding, to spring out upon Maxime Dalahaide as he crept toward his friends and far-off safety. There was no sound except the crisp rustle of the water as the launch cut through it; but as they entered the lagoon, where among tall reeds the image of the moon lay unbroken like a fallen silver cup, a whispering ran through the rushes, as if to pass the news of their approach from ear to ear.
