Briefly the boys gave a synopsis of the events already known, not forgetting to mention the dangerous situation in which their enemy had succeeded in placing them only a short time previous to the present.

Not a word of the story was lost by either the officer or the sergeant, who occasionally exchanged quick glances full of meaning.

"You surely have occasion to suspect this person whom you call 'The Rat,' and I am sure your efforts will be crowned with success," the sergeant offered, at the conclusion of the story. "However, my orders are to detain you if found, and present you at the War Office. You will, of course, appreciate my position and understand what 'duty' means."

"Yes, sir," Ned returned, "we believe we know what 'duty' means, and we surely cannot object to your doing yours, but we would like very much to know where this man we referred to is located at the present."

A smile overspread the face of the sergeant.

"He is under surveillance. He cannot get far away until permitted to do so by agents of the War Office. Although his credentials appeared to be fully as valid as your own, we cannot afford to take risks at such a time as now. He will be produced in good season."

"Thank you!" Ned replied heartily. "I feel easier now, and hope our mission is nearly accomplished. If we can once obtain extradition papers and return the fellow to the United States we shall be pleased."

"When can we visit the War Office, and lay our case before the proper officials?" asked Harry eagerly. "We don't want to lose any time!"

"Perhaps not before morning," was the answer. "It is late now."

"Isn't it possible to get someone on the telephone?" suggested Jack, indicating the instrument at the sergeant's elbow as he spoke.
