"So—it is you?" he said. "I thought I had not seen the last of you on the platform at Virballen! Lieutenant, you may leave us."

"Yes, general," said the lieutenant who had rescued Fred. He was plainly puzzled and confused. "I did not tell your kinsman that you were in command here. I thought he would be delightfully surprised by being confronted with you suddenly. But—"

"Exactly! You were quite right, lieutenant. And now you may leave us!"

The lieutenant flushed at the rebuke, saluted stiffly, and left the room.

Fred was alone with his uncle.

"You are brave, at least," said Mikail, presently. "That will, perhaps, be a comfort to you later. Yet you were not well advised to serve the Germans as a spy. They have not been able to save you from me this time, you see. It is not a case this time of the station at Virballen, with the superiority of numbers on their side for the moment."

"It is your Cossacks who saved me from the Germans," said Fred. "I have been a spy—but it has been in the interest of Russia. General Alexander Suvaroff and his son can tell you that."

"Perhaps," said Mikail, his eyes and mouth fixed, so that no one could have guessed what was in his mind. "It is strange that you feel forced to call upon those who cannot say anything for or against you—since they are in the hands of the Germans."

Inspiration came suddenly to Fred, and he said nothing. He gave his uncle stare for stare.

"Well, what have you to say?" said Mikail, at last. "What defence have you, spy?"
