friends there soon heard the news, and even about the exact place where he is being held."
"What are they holding him for?" asked Ned.
"That's explained, too. It seems they can't legally take him back until certain papers are received from his former prison in Siberia, and those are now on the way. His friends write to me to hasten and rescue him."
"But how did they ever get your address?"
"That's easy, though you wouldn't think so. It seems, so the letter explains, that as soon as Mr. Petrofsky got acquainted with us he wrote to friends in St. Petersburg, giving my address, and telling them, in case anything ever happened to him, to notify us. You see he suspected that something might, after he found he was being shadowed that way.
"And it all worked out. As soon as his friends heard that he was caught, and learned where he was being held, they wrote to me. Hurrah, Ned! A clew at last! Now to wire the detective—no, hold on, we'll go there and rescue him ourselves! We'll go in the airship, and pick up Detective Trivett in New York."
"That's the stuff! I'm with you!"
"Bless my suspender buttons! So am I, whatever it is!" cried Mr. Damon, entering the room at that moment.
