"Do not be too sure of that," Dave retorted. "It may be that our information is more exact than you suspect."
"Have you anything definite to say on that subject?" demanded the ober-lieutenant, regarding his prisoner attentively.
"Naturally not."
"Then, as I shall be busy, will you be good enough to return to the bounds set for you?"
Dave bowed, turned and re-entered the passage-way. The German naval officer's manner toward him had not been insulting. There was an evident effort to treat Darrin with the outward show of respect that should be accorded to a prisoner of his rank. Yet Dave knew that his enemy hated him.
Mr. and Mrs. Launce were in the passage-way, and Captain Kennor could be heard stirring in his cabin.
"Mr. Darrin, we are now at good depth under water?" inquired Mr. Launce.
"Yes, sir; I believe so. We are not to be caught and destroyed just yet."
"That I am sorry to hear," replied the lawyer, gravely.
"And, I, too, am sorry," spoke up Mrs. Launce. "Life has been sweet to me, but I would much rather be dead than a captive in Germany. I condole with you, Mr. Darrin, that it was not possible for you to bring about the destruction of this wretched craft."
