Ivan was a loutish German in appearance, and only his eyes betrayed the fact that he was not as stupid as he looked.  At the sight of Boris he smiled, and the act changed his whole expression.  But Fred thought he had never dreamed of so splendid a disguise.  This man, he guessed, must have come many miles through Germany, in a country where the closest possible watch was being kept for spies, and for all, indeed, who might even be suspected of espionage.  And it was easy to see how he had been able to do it.  Fred knew that he must be a Russian.  Yet in every detail of his appearance he was German.  His clothes, his bearing, his every little mannerism, were carefully studied.  Fred guessed that this was no servant, but a secret agent of much skill and experience.  He was to learn the truth of his surmise before many days had passed.

“Ivan Feodorovitch!” said Boris.  “So you really got through!  Have you brought the—­”

He stopped at a forbidding look in the man’s eye.  For a moment he seemed to be puzzled.  Then he understood that it was the presence of Fred, a stranger, that was bothering Ivan.

“Oh!” he cried, with a laugh.  “Ivan, you may speak before this stranger as freely as before me.  Let him be a stranger to you no longer.  He is my cousin from America—­the son of Marie Feodorovna, who went away to be married before I was born!”

Fred was not prepared for what followed.  There was an outcry, first of all, from the half dozen servants in the great hall.  They crowded forward curiously to look at him.  And as for Ivan, he stared blankly for a moment, and then plumped down on one knee and, to Fred’s unspeakable embarrassment, seized his hand and kissed it.

“He and all of them are old, old retainers of our house,” Boris explained swiftly.  “To them one of our blood ranks second only to the Czar himself.  My father saw to it always that here we were surrounded only by such faithful ones.  These people and their ancestors before them have been in the service of us and of our ancestors for many, many generations—­since before the freeing of the serfs, of course.”

It was Boris who brought Ivan back to the errand that had caused his sudden appearance.

“Have you brought the parts for the wireless?” he asked.  “It was as my father foresaw.  The first thing the Germans did was to come here and render the installation useless, as they supposed.”

“It need not remain useless,” said Ivan.  “Everything needful I have brought.  The station may be working by to-night.  Except that there can not be anything worth sending for a few hours, it might be set up now.  Better not to use it and risk betraying our secret until there is real need of it.”

Boris turned to Fred to explain.

“We have spies all through East Prussia, and through Galicia and Silesia, too, of course,” he said.  “They can find out a good many things of interest and importance to our army.  But it is one thing to obtain such knowledge and quite another to find some means of sending it back to our people.  We hope, if we are not sent away from here too soon, that we can make this house very useful that way.  It stands high, you see, and we have a very powerful wireless.  The Germans knew this and they thought they had made it useless.”
