sand German marks."

"H-m-m-m," muttered the colonel, eyeing the lad keenly. "Even if you can
do what you say, the price is rather high. I'll give you five hundred."

Hal seemed to consider.

"All right," he said at length. "It's a bargain. Turn your car about and
I'll take you to their hiding place at once."

"Very well."

The colonel stepped into his automobile, and, after a series of attempts,
finally succeeded in turning it. Then to the others:

"Climb in," he said briefly.

Ivan climbed into the rear seat, while Hal took his place beside the
Bulgarian.

"Straight ahead until I tell you to stop," the lad instructed.

The Bulgarian officer asked no questions.

A few minutes later the machine drew up in response to Hal's command. All
dismounted.

"They are all back here a little ways," said Hal.

The Bulgarian officer followed Hal toward where the lad knew the others
were in hiding. Under the tree where he had left Helen, Hal paused. Then

"So?" exclaimed the Bulgarian. "Well, you can't have it."

"We'll see," said Hal quietly. "Here, Ivan! You guard this fellow, while
I have a look at the car."

He examined the machine carefully.

"All right for a quick dash, I guess," he said finally, rising from his
inspection. "All aboard!"

Every one obeyed, and soon all were seated in the car save Hal and
Chester, who were to occupy the front seat. Hal also motioned the
Bulgarian into the front seat.

"He may come in handy after awhile," he declared.

Everything in readiness at last, Hal and Chester climbed in and Hal took
his place at the wheel.

"I'll do the chauffeuring," he said, with a smile. "I may have to do some
talking later and I want to be runnin
