"Better see to our guns," said Colonel Anderson quietly.

He examined his own brace of revolvers carefully, and Hal and Chester did the same. Uncle John was unarmed.

"Too bad we didn't stop and get the guns of the officer I knocked down back there," said Hal. "However, it's too late now. We'll have to get along with these."

"Perhaps they won't find this place in the darkness," said Uncle John hopefully.

"Don't fool yourself there," said Chester. "They'll find it all right. That is their business, right now. Besides, it's not so dark as it was when we arrived."

"Maybe they won't take the trouble to look in," persisted Uncle John.

"They'll look in, all right," replied Hal dryly.

"Whoa!" came a voice in Austrian from outside.

Other voices became audible.

"Maybe they are in this old shack," said one.
