en exist, falls on deaf ears when you
address me. I hope that you will be summoned before a British court and
that you may be sentenced to pay the full penalty for your crimes!"

Dreiner's face went ashen-gray as he staggered to his feet. Probably he
really was concerned for the fate of his children, but his was not the
sort of record that invited pity.

"I will not detain you here," Dave finished coldly. "If I did, I might be
tempted to abuse a prisoner, and that is something no American fighting
man can really do. Orderly!"

As the orderly stepped in, saluting, Dreiner tried a last appeal:

"Why do you hate us Germans so?" he whined. "I know that you do not hate
me especially, but that you hate all of our race!"

"Why do we hate you?" Darrin echoed. "The reason is that, from all we
hear, fellows like yourself appear to be fair samples of the German

I can think of other reasons to give you. I would rather not, for it
brings me perilously close to the offense of abusing a prisoner, and that
I do not wish to do. Orderly, call two men and instruct them to take
Ober-Lieutenant Dreiner below to join the other prisoners."

As the German stepped past the Yankee commander he glared into Dave's
face, hissing:

"To-day it is your chance to humiliate and condemn a German. It may not
be long ere your turn comes, and a German officer tells you what your end
is to be!"

"I am ever at Fate's orders," Darrin answered, with a bow.

CHAPTER XXI

ON A MISSION OF GREAT TRUST

WHEN the "Grigsby," in broad daylight, steamed into the base port with a
captured submarine and her crew, and a German commanding officer who was
liable for a dastardly crime at sea, there was great rejoicing both on
the other naval vessels and on shore.

If the German prisoners expected a stormy reception when they were landed
and placed under a guard of soldiers, they were disappointed, for nothing
of the sort awaited them.

The British populace, though it turned out to see the captives marched
through the streets, proved to be too good sportsmen to make a violent
demonstration against their now helpless enemies.

Darrin had no sooner turned over the prize and made his report to the
British admiral than he was ready for sea once more.

"Mr. Darrin," said the admiral, heartily, "when you went out the other
day you promised to show me results. I take this opportunity t
