The captain in command of the cavalry squadron gave a sharp command and
his men drew rein while the officer came forward. He glanced at the
colonel in the automobile and saluted.

"Oh, it's you, sir," he said. "Have you seen anything of the fugitives?"

The Bulgarian felt the pressure of Hal's revolver in his back.

"No," he said.

The captain saluted and would have passed on, but Hal instructed his
prisoner to ask:

"How far are we from the Greek frontier?"

"Less than a mile," was the answer. "There is but one more body of our
troops between here and a strong force of Greeks, which is patrolling
the border."

The two Bulgarians saluted each other and the troop separated to make a
path for the automobile.

"Another close shave for all of us," said Chester, when they had passed
by. "You, too," he said to the Bulgarian. "You'd have been a goner if you
had sought to give the alarm."

A few minutes later Hal made out another body of troops blocking the
road. He reduced the speed of the car and spoke to the others.
