off, and Frank slipped them on over his own.

It was with a shudder of repulsion that he saw himself clad in the
detested uniform that stood for all that was hateful and brutal in
warfare. It made him feel soiled. But he comforted himself with the
thought that the clothes were only external and that good United States
khaki lay between that abhorred uniform and his skin.

He saw that the gag was still securely in position and that his
captive's bonds had not relaxed. Then as a last reminder he laid the
back of his knife on the prisoner's neck and felt him shiver beneath
the cold steel.

"I guess he'll make no attempt to give me away," he said to himself.
"He knows that he'll be all right in the morning anyway."

Slowly and with the infinite precaution that had been taught him in his

CHAPTER III

AMONG THE MISSING

Frank's heart was beating like a triphammer and his nerves were at a
fearful tension. The next five minutes would probably determine
whether he was to live or die.

But he kept himself well in hand and to all appearances he was only a

As far as he could without attracting attention, he kept carefully away
from the low fires around which some of the Germans were sitting. But
at one point he was forced to pass within the zone of light, and one of
a group threw a laughing remark at him, occasioned probably by the cuts
in his coat which he had been compelled to make when he had stripped
his prisoner.

"_Asel!_" Frank flung back at him and passed on, thankful that he at
least knew the German term for jackass.

Nearer and nearer he drew to the confines of the camp. Here the great
danger lay, for he knew that it would be closely guarded after the
day's fighting.

If he were challenged what should he say? To the sentinel's "_Wer
da?_" he could answer "_Freund_." But when he was told to advance and
give the countersign what would be his answer?

He had it ready. But it would not suit the Germans.

At the point that he had selected for his attempt, there was an opening
