of spirit. "He is young, but
he has done more to discover the truth than any of them. He has brought
information of the concentration of the Austrian troops along the Drina.
It is through him that they learned where the stores and supplies were
being massed in the mountains there. I told you yesterday of the plans
that were made for a Servian raid, but it was too late. A raiding column
crossed the Drina last night and destroyed most of the stores you had
collected."

"There has been a leak somewhere in my own place!" said Hallo, savagely.
"Even the men who executed the orders did not know where those supplies
were going! I trusted no one!"

"That is just the bad part of it, master," said the spy. "They will be
saying next that you yourself gave away the truth to the Servians."

"Who will believe them?"

"If it is known that you have been in touch with Milikoff?"

"It is known, fool! It is known that I am treating with them simply to
gain information of their plans. But now--it is no time for talk. We
must move quickly, or they will explode their mine."

"Jan!" he cried. "Jan!"

And then Dick's heart sank. That must be meant for Steve--and to answer
meant deadly peril for Stepan Dushan, since the spy, who had so plainly
been betraying Servian secrets to Hallo, knew Stepan. Dick edged

very close to him. They stood just by the box that sheltered him.

"Jan!" cried Hallo again.

"Here I am!" said Stepan's voice. And then, "Serge!"

"Stepan Dushan! That is Stepan Dushan!" shrieked the spy.

Then, before anything more could happen, Dick had an inspiration. He
threw his whole weight against the heavy packing case, straining,
pushing. It trembled, gave, and then crashed down, bearing Hallo and the
spy down beneath its crushing weight, sending them down, stunned and
helpless.

CHAPTER XIII

FACE TO FACE

"You, Dick? Thank God!" cried Stepan. Then his face flushed, and he came
forward, furiously. He dragged the spy out, looked at his face, and then
spurned him with his foot.

"You saved my life, I think, Dick," he said, simply. "I never suspected
this! Treachery in our ranks. I had not supposed that any Servian would
sell his country. Mike Hallo, of course, we never trusted--but this man!
Well, he will pay in one way or an
