d to play considerably when I lived in the
United States, and for that reason, I guess, I was on my guard."

"At all events," said the second German, "you have done us a service and
we wish to thank you."

"Why, that's all right," said Stubbs. "I am sure either of you would have
done the same thing under the circumstances. And with your permission, I
shall leave you now."

The others bowed and Stubbs turned toward the door.

"If you will wait a moment, sir, I shall accompany you," said a voice.

It was Hal who spoke and Stubbs waited obediently.

"First," said Hal, "I have something else to do." He addressed the
Germans: "Which of you is upon the staff of General Ludwig?"

"Why, I am," said one of the men, stepping forward.

"Good!" said Hal. "I would have spoken sooner, but I was absorbed in the
game. I did not remember your name, but I was sent for you. Will you
follow me?"

The German nodded his head.

"Very well," said Hal. "Come."

He led the way from the tent and the German and Stubbs followed. The

Outside, they walked along slowly.

Five minutes later, when they reached a place that was somewhat
secluded, Hal suddenly produced his revolver and pressed it against the
German's head.

"You will give me immediately what papers you have in your pockets,"
the lad said quietly. "If you make an outcry I shall be compelled to

"It means that I must have whatever papers you possess," said Hal,
calmly, "even if I have to shoot you to get them."

"Ah!" cried the German, "I see! A spy!"

He made a move as though to seize Hal, but the lad was too quick for him.

With his left hand he grabbed the German's elbow in a tight grip and
squeezed. Then, even before the man had time to cry out, the lad released
his hold, reversed his revolver quickly and brought the butt down on the
German's head with all his force.

The man crumpled up without a word and lay still.

Stubbs, who had witnessed this proceeding in open-eyed wonder, now
uttered an exclamation.

"What are you doing? Trying to get us both killed?" he demanded.

Hal did not reply. Stooping over the prostrate German he ran his hand
quickly through the
