The colonel nodded.

“Yes, he is a westerner by birth, I believe, but that makes little difference to men of his type. The only country they know is the one that gives the biggest price for their rascalities.”

“He ought to be shot for trying to betray the country he owes his birth to,” said Jack hotly.

The colonel smiled and laid a hand on the excited lad’s shoulder.

“You feel about it as I do, lad,” he said. “But remember we have nothing to go upon as yet. Absolutely nothing.”

Jack agreed that this was so, and after some more conversation, the colonel left the wireless room, first warning the young operator that their talk must be held absolutely confidential.

Of course Jack promised this, and so did Sam. But both lads felt that they were playing parts in a big game, the nature of which was an absolute mystery so far.

“It’s like sitting on a keg of dynamite,” said Sam.

“Yes; I have a feeling that there is something electrical in the air,” said Jack, “besides wireless waves. It may break at any minute, too.”

“If it does, I hope we get a chance to help out the colonel.”
