"For myself," put in Hal, "I'd suspect that fellow Gaston, in an instant, if he had only been at liberty. That fellow has an eye that looks like all the letters in the word 'r-e-v-e-n-g-e.'"
"That's so," nodded Jack, thoughtfully, as he ate. "But we happen to know that Gaston is very safe under lock and key. By the way, fellows, I don't suppose Mr. Farnum and Mr. Pollard have heard the news yet, or they'd be out here on the double quick."
After breakfast Jack went ashore alone, to carry the exciting news to his employers. He found Messrs. Farnum and Pollard in the breakfast room at the Clayton. Both were astounded when they heard the news of the night's doings.
"Who on earth could have put up such a job against the submarine?" gasped David Pollard.
"I don't know, sir," Captain Jack replied. "But I've left Hal on board, in command, and I mean to find out something about this business, if there is any way to do it."
With that he excused himself, rising and leaving the table at which his employers were seated.
Jacob Farnum gazed after his young submarine captain, then whispered to the inventor:
"That youngster has some notion in his head of where to look for the infernal criminals. And, ten to one, his idea is a good one that will bear fruit!"
