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 he raised his voice a trifle and called aloud, at the same time drawing his revolver and presenting it squarely at the Bulgarian’s head: 

“Chester!  Oh, Chester!  You can all come down now.”

In response to this hail, Chester, Helen, Mr. Stubbs and Nikol soon stood before them.

When Hal drew his revolver, the Bulgarian officer staggered back.

“A traitor, eh?” he exclaimed.

“Why, no,” said Hal, and he removed his heavy cap.

The Bulgarian gave a long whistle and ejaculated:  “One of the fugitives himself.”

“So you know me?” said Hal.  “Well, then you should know me well enough to do as I say.”

“What is it you want?” demanded the Bulgarian.

“Nothing very difficult,” declared Hal.  “First we want to borrow your automobile for a few hours.”

“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 running this animal, so I can know what to do without having to talk.  Keep your eye on our friend, there, Chester.”

“I’ll hang on to him, all right,” replied Chester grimly.  “He’ll not get away from me.  Have no fear of that.”

“All right,” called Hal.  “Everybody ready?”

He glanced around quickly.

“All ready,” came in Colonel Anderson’s voice.

The others nodded their assent and an instant later the machine darted southward at a rapid gait.
