"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.
