“Will you be good enough to speak more explicitly?”

“Certainly,” Dave assented. “When you are turned over to the British military authorities it will be done with a card showing that you now give the name of von Bechtold——”

“Which is my right name,” interposed the German officer, tartly.

“And the card will also state that, a few days ago, you gave the name of Matthews.”

“Again you use that name of Matthews,” cried von Bechtold, impatiently. “May I ask why?”

“I will make it so clear,” Dave promised him, “that you would understand even though what I am about to say were not true. But it is true. A few days ago you met me at the hotel in port. You met also my executive officer, Mr. Dalzell. You introduced yourself to us as Matthews, claimed to be a buyer for a Chicago dry-goods house, and declared that your mission was to buy linen.”

“Not a word of truth in it,” declared von Bechtold, calmly, with a wave of his hand, as though to brush aside the charge.

“Unfortunately, quite true,” Dave went on, steadily. “You were there under an assumed name and claimed to be an American citizen. You exhibited an American passport; I have heard that your government has a printing office where such documents are turned out. You were there out of uniform. In other words, sir, your conduct on British soil, in civilian dress and under false colors, met with all the requirements of proof that you were there as a spy. It has long been known to the British, and to us, that German spies have abounded in Great Britain and that they obtained a good deal of information that we would rather German submarine commanders did not possess. So, Mr. von-Bechtold-Matthews, it will be my disagreeable duty to hand you over with the charge that you have been serving as a spy. Dalzell and I will be obliged to testify against you. I much fear that a British court-martial will condemn you to be shot.”

“What infamous lie is this that you are threatening to utter against me?” demanded the German officer, leaping to his feet.

“No lie at all, as you know quite well,” Dave went on. “I am sorry to have to bring you to this plight, von Bechtold, but you know that I cannot do otherwise.”
