However, Steve was a skillful handler of the swift little craft. Darting forward when the flashing of a light left a space dark, turning this way and that, coming almost to a full stop when the river ahead was suddenly lighted, he played hide and seek amid the great, flashing beams of light. And at last they were well beyond them, and could sweep across the river and come to the safe haven of the little wharf on the Servian shore.

A few explanations then, and Steve reluctantly turned over the boat he had guided so well to another, while he and Dick, with Hallo and one of the other men who had come with them, tumbled into a military automobile that was waiting. There was a swift rush to the citadel, where Steve turned over his prisoner.

"He's a slippery customer," Dick said, in warning.

"He won't get away from us," the officer promised.

And then—sleep! Sleep that was almost as welcome as it had been the night before or, rather, the morning before. For again they had been busy through all the hours of darkness, and it was daylight before they got to bed.

This time, when Dick awoke at last, Steve was still there, and he yawned luxuriously when Dick woke him up.

"Nothing to do to-day!" he said. "At least, nothing that I know of now! It's a real holiday, Dick. I can tell you it feels good, too. I wouldn't have missed the chance to do what I've been able to do for Servia, but I'm tired now."

"I should think you would be," said Dick. "You haven't only had to work hard, but there's been the chance always that you would be caught."

"I know. But I didn't think much about it, Dick. I was too busy. The chief danger was that Hallo would find me looking through his papers some time. He might not have suspected that I was a spy, but that would certainly have ended any chance there was for me to get more news."

They got up then, and enjoyed a great meal at their leisure, while old Maritza looked on and kept their plates full, and scolded Stepan for having caught cold the night before. She said he must have caught cold, because he was hoarse, and laughed at him when he said it was only because he had been so tired.
