weep 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.

"You say there's nothing for us to do?" asked Dick.

"Yes, but I didn't mean it. There's plenty to do, only it's stupid
compared to the sort of thing we have done. There are errands of all
sorts to be run, and I believe that there is a good deal of help to be
given to the poor people. It's mostly their houses that have been
knocked about in the bombardment, you see. We don't have to do it, of
course. The rest of the scouts here have been busy that way, and I'm
excused from that sort of work because I was detailed to this special
service. Still I think I'll lend a hand until there is more work for me
from the Intelligence Department."
