"The only fault to be found with you," continued the ober-lieutenant, "is that you had the misfortune to be found in such company, and that later on your tongue might prove too long and ready. That is all!"

Von Sch.e.l.len, again on his feet, signalled to some of the seamen, then said:

"The prisoners will follow me."

To the amazement of all he led the way to the conning tower. After him the sailors herded the four prisoners of war. They ascended the ladder, the Englishwoman being the last of the four. Her husband and Captain Kennor a.s.sisted her as she stepped through the manhole to the deck outside.

"But this is unkind," she declared, with a shiver. "My husband and I have not our outer wraps, and the night is chilly."

"I will mention the matter," replied von Sch.e.l.len, stiffly.

The wireless masts and aerials had disappeared. As the four pa.s.sengers stood on the deck and wondered, the seamen entered the submarine through the manhole in the wake of von Sch.e.l.len. When the last of them had gone into the conning tower the junior lieutenant re-appeared at the manhole to call:

"A pleasant evening for four!"

Then the manhole cover was closed and there came to those on deck a m.u.f.fled sound connected with fastening it on the inside.

"What does this new insolence mean?" cried the Englishwoman.

"If you do not guess, you must soon know," replied her husband, throwing an arm about her. It was then that Mrs. Launce understood. She turned pale, but did not cry out.

Perhaps a full minute pa.s.sed before the submarine began to move forward.

Dave Darrin, familiar with the sounds from below, knew that the rumble of machinery coming to his ears was caused, not by the engines used in surface running, but by the electric motors employed when running under water.

"The brutes are going to drown us, as they did the hapless sailors they took from our boat!" gasped the Englishwoman.

"Yes, my dear," replied her husband, "and you have said that you would prefer drowning to being a prisoner in Germany."

"I still say it," she answered quietly.

"We are to have our wish," said her husband.

Dave Darrin remained immobile; Captain Kennor shrugged his shoulders without speaking.

The prow of the craft dipped into the water, which soon came creeping up around their ankles. The forward deck was now out of sight, the water in which they stood rising toward their knees.

CHAPTER XIII

FACING THE PLANNED DEATH

TURNING to Darrin the Englishman held out his hand.

"Good-bye" he said, simply. "You have been a good comrade. I trust you have not been disappointed in us, either."

"Let's not say good-bye yet," urged Dave cheerfully. "Surely we are not going to give up and drown, merely because a lot of German rascals so will it."

"But we cannot last long in the water," protested the Englishman, mildly.

"At least, sir," Dave suggested, "we shall not die until we have to. You swim?"

"Once I did."

"Then you can swim now. The sea is nearly smooth. Let us try to keep together. And you, Captain Kennor? You swim?"

"Yes."

"Good. We'll keep together as long as we can."

At this moment the Englishwoman, the shortest of the quartette, gave a little cry as she found her footing giving way beneath her.

"All together!" cried Darrin, with a cheeriness he did not feel, as he gripped the woman's left arm.

Another drop of the deck sent them all adrift. The Englishman supported his wife on her right. Captain Kennor, nearly silent, but undaunted, swam slightly behind the others that he might offer aid wherever needed.

Strangely enough, though the swimmers spoke to each other occasionally, none now referred to the dastardly conduct of the enemy in setting them thus adrift to drown.

"You are cold, my dear, I know," said the Englishman to his wife. "Are you suffering otherwise?"

"No; but though I would not willingly drown myself, I shall not be sorry when we give up and go down."

"Had I felt that way the last time I found myself in the water," spoke up Dave, "I would not be here now."

"You had on a life belt. Now none of us has," answered the Englishwoman, her teeth chattering. "We cannot last long."

"After my last experience, madam," Dave a.s.sured her, "I shall never dare say that as long as life lasts."

"Why not face facts calmly?" she asked. "Probably I shall last a quarter of an hour before I die of cold. I may survive for twenty minutes or a little longer. You are strong, and may keep up for an hour or more. What can possibly come to our aid in that short time?"

"Who can say?" was Dave's counter-question.

For some time, they swam in silence. They did not attempt to make progress. Motion enough to keep afloat was all that was called for.

All at once Dave wondered whether his eyes were playing him tricks, or whether he really saw the top of a conning tower approaching him. It was not likely that the enemy would remain about, and come back to see how it fared with the victims of their cruelty.

Then the something in the water took on another vague shape. Darrin shook his head in an effort to get the water out of his eyes. He peered again.

The shape, whatever it was, and if it really existed, was beginning to get on his nerves. It seemed to come nearer.

"Captain Kennor!" called Darrin, sharply.

"Aye!" responded the Dane.

"Are you still swimming strongly?"

"Aye!"
