A heavy plunge at that moment told that the conspirators were not only trying but had succeeded, for the plunge was followed by an irresistible though powerfully suppressed cheer.

“We have not a moment to lose, Otto,” whispered Dominick. “The ship is free, and they will only take time to carry the tackle aboard before embarking. Do you run back and bring the squad down at the double. I will keep our friends here in play till they come.”

Not a word did Otto reply. He had acquired that first of requisites in a soldier or servant—the habit of prompt obedience. Somewhat like a North American savage, he sank into the grass and wriggled from the scene. A few moments later Dominick rose, and walked down towards the conspirators with the easy off-hand manner of a man who saunters forth to enjoy the night air. So busy were they getting the tackle into the boat that he was not observed until quite close to them.

“You seem busy to-night, friends,” he said, in his usual pleasant tones, as he took his stand close beside Hugh Morris, who was near the bow of the boat.

“Mr Rigonda!” exclaimed Malines in great surprise, coming forward at the moment.

“Why are you surprised? It is not unusual for me to take a row on a fine night.”

This reply seeming to imply that Dominick had come to the reef alone—perhaps in the dinghy—emboldened the men; some of them laughed.

“Well, I confess to being a little surprised, sir,” replied the mate, “for it so happened that we were preparing something in the nature of a surprise for you and the rest of the settlers.”

“Yes, I see,” returned Dominick, in the same pleasant tone. “You’ve managed to get the ship off the ledge in a very creditable manner, and you mean to take her into the lagoon and cast anchor off the settlement?”

Again the men laughed lightly.
