“Yes. We’ve got sufficient here in the boat, for such an emergency. We’ll row back now, and get busy.”

Dynamite was presently placed at the base of the ship’s two masts and amidships, and the fuses lit. They then rowed swiftly away, and had hardly reached a position where they would be out of danger, when the explosion came. Three crashes, one after the other, shattered the sides and decks of the vessel. The Merrymaid was sinking rapidly. First her bow filled; then the gallant yacht stood perpendicularly on her prow, and slid with a rush out of sight.

At the instant her funnel plunged under, a final tremendous explosion took place, throwing a cloud of steam and water high into the air. A moment later, only a vortex of oily, tossing water gave evidence that a million dollar yacht had gone to the bottom.

“It’s a dirty shame!” Bill spat the words without caring whether the Baron took umbrage or not.

“It is indeed,” that blond giant answered seriously. “But this is war, remember. I cannot use her, still less can I afford to have her discovered. Yes, it is a shame. Vandalism, if you like, but none the less, a necessity.” The Baron shook his head, then went on pompously: “An hour ago that splendid little ship might have been of great service to mankind. Now she is no more. Let it be her epitaph that she was fulfilling her destiny, with work well done. May the world say the same of me when I have gone to the eternal reward.”

Bill kept silent and managed to conceal his disgust. He did not appreciate such philosophizing. Neither could he agree with the Baron’s estimate of his own worth. His work might be well done, but in itself piracy on the high seas could hardly be called more than a disgraceful profession. Bill began to realize that the commander’s brain, although active enough, was more than slightly warped.

They rowed over the spot where the Merrymaid had gone down, and looked about for any stray bits of wreckage which might have floated to the surface. They found none, so made for the amphibian at once.

“You will wait until you see us take off before you do the same, Mr. Bolton,” directed the Baron with a return of his superior-officer manner, as Bill boarded the plane.

“Aye, aye, sir. Any further orders?” Bill returned the military manner with interest.

“Yes. You will follow my craft as though you were number two of a patrol. Land when I land, and taxi over for further instructions.”
