"But we're American citizens!" cried Tom, "and—"
"You forget that I am not," interrupted Mr. Petrofsky. "I can't claim the protection of your flag, and that is why I wish to remain unknown. We must act quietly. The more trouble we make, the more important they will know us to be. If we hope to accomplish anything we must act cautiously."
"But my airship!" cried Tom.
"They won't do anything to that right away," declared the Russian in a whisper for he knew sometimes the police listened to the talk of prisoners. "I think, from what I overheard when they arrested us, that we either trespassed on the grounds of some one in authority, who had us taken in out of spite, or they fear we may be English or French spies, seeking to find out Russian secrets."
They were served with food in their prison, but to all inquiries made by Ivan Petrofsky, evasive answers were returned. He spoke in poor, broken Russian, so that he would not be taken for a native of that country. Had he been, he would have at once been in great danger of being accused as an escaped exile.
Finally a man who, the exile whispered to his Companions, was the local governor, came to their prison. He eagerly asked questions as to their mission, and Mr. Petrofsky answered them diplomatically.
"I don't think he'll make much out of what I told him," said the exile when the governor had gone. "I let him think we were scientists, or pleasure seekers, airshipping for our amusement. He tried to tangle me up politically, but I knew enough to keep out of such traps."
"What's going to become of us?" asked Ned.
"We will be detained a few days—until they find out more about us. Their spies are busy, I have no doubt, and they are telegraphing all over Europe about us."
"What about my airship?" asked Tom.
