Gazing into the steady eyes of the young American naval officer von Bechtold realized the folly of further acting. Breathing hard, he dropped into a chair.

“It is not a fine thing that you propose to do to me,” he declared. “You do not know, of course, that I have five young children at home, who will need a father.”

“I did not know it,” Dave answered gently. “Yet I feel quite certain that some of the information you have gathered, when ashore in these parts, has resulted in the drowning at sea of a good many men who may have left behind even more than five children.”

“I feel that I am doomed,” shuddered the German, throwing a hand up over his eyes. “My five little children will not see their father again—not even when this war is over.”

“It is too bad,” Dave answered, “but I suppose, Herr Ober-Lieutenant, that it must be classed with the fortune of war. Now, as to the identity of the civilian who lies dead in a berth aboard your late command, it may be that, if you were ready to tell something about the reasons for his presence on board, and why he had in his possession this paper——”

Here Darrin spread out the wet sheet of paper that he had brought from the submarine.

“I can tell you nothing about either the civilian or that paper,” declared von Bechtold, doggedly.

“That is your own affair,” Darrin admitted. “I shall not make any attempt to force you.”

“You had better not!” declared the German, fiercely. “I can die, but I cannot betray my country. Yet have you no heart?—when I tell you about my five little children whom you would deny the privilege of ever seeing their father again?”

“If I were to suppress my report of your activities as a spy,” Darrin continued, “I would be guilty of betraying my country and my country’s allies. It would also be necessary for me to induce my subordinate officer to do the same thing. You will realize the impossibility of our doing such a thing. On the other hand, between now and the time that you are tried by court-martial you will have time to reflect upon whether you wish to try to save yourself from the death sentence by explaining to the British authorities the full meaning of what had been written on this sheet of paper and also the reasons for that civilian being aboard your craft. Then, by throwing yourself on the mercy of the court, you might escape the full penalty meted out to a spy.”
