After that, gloom fell upon the trio. Darrin had never heard, before, of the Earl of Denby. Later he learned that the Earl had led a recluse"s life among books until the war began. About that time he had married a young n.o.blewoman, and the pair had gone promptly into effective war work, though not in ways that caused their portraits to be published in the ill.u.s.trated weeklies.
Von Sch.e.l.len re-appeared five minutes later, casting first a look of triumph at the English couple, next turning to Dave.
"The American officer may take the air briefly on deck if he so desires,"
said the German. "It is by gracious permission of the commanding officer."
Darrin"s first impulse was to decline, unless his companions were included. He changed his mind, however, for he had an intense desire to find out, if possible, in what waters the craft now was. So he rose, bowing to his table companions, and followed von Sch.e.l.len to the conning tower ladder. Here he pa.s.sed Herr Ober-Lieutenant and bowed stiffly.
"I am trusting you on deck," said the latter, with a frown. "It is a courtesy. Do not abuse it by any untoward conduct."
Then Dave followed his conductor up into the tower, von Sch.e.l.len all the while keeping sharp lookout to see that Darrin did not attempt to do any damage to the levers on the indicator board.
Von Sch.e.l.len, preceding him to the deck, turned to say, as Darrin reached the platform:
"Observe. Your desperate trick did not harm us for long. You will note that the periscope is again lowered. In fact, a new one has been put in its place. We have tested the new periscope and its bearings, and have found that they work perfectly. Your treachery, with which you repaid the commanding officer"s courtesy, did not avail you much."
Darrin did not reply. Instead, he turned to survey the night on all sides. Overhead were heavy clouds, obscuring the light of the moon, which, in its present phase, would have furnished considerable light over the waters. There was a fine mist in the air, but the sixth sense of the sailor warned Dave not to expect rain tonight.
Despite the cloudiness, however, one could see for a considerable distance over the slightly rolling sea. There was no other craft in sight.
"You do not see much hope," mocked von Sch.e.l.len. "We have chosen a quiet part of the sea, as you will notice."
"You usually try to do that, don"t you?" Dave asked, in a tone of ordinary curiosity.
"You must know," laughed the junior officer. "You have spent months pursuing our submarines."
"And have had some success in catching them," Dave answered.
Von Sch.e.l.len"s laugh was bitter as he rejoined:
"Ah! You are a good boaster! But do not go too far, Herr Darrin! Do not make me wish to strike you!"
"I wouldn"t care how soon you struck me," Darrin smiled, "provided I could be a.s.sured of a fair field and no favor in defending myself. But I think we are going too far in our talk, are we not, when one considers the consideration that a captor must show to a prisoner of war. As a gentleman you cannot strike me; nor, as a gentleman, can I seek to provoke you to do so. The situation is one calling for tact, Herr Lieutenant."
"And I cannot forget that you are taking occasion to remind me of the fact," retorted von Sch.e.l.len, a dark look coming into his face.
"Then may I, as the prisoner of war, ask that the subject be changed?"
Dave Darrin suggested.
"By all means," von Sch.e.l.len returned, quickly, though he was able to perceive that the American had again succeeded in putting him in the wrong.
Just a moment later a petty officer appeared on deck. Taking two or three steps toward the junior officer he halted, saluted, and then remained standing at attention, as though waiting.
Von Sch.e.l.len stepped over to the man, and a conversation followed in low tones, but did not last long.
"If you care to remain on deck and watch," said the junior lieutenant, "you will see something that may interest you."
CHAPTER XII
GERMAN BRUTALITY AT ITS WORST
JUST behind the conning tower a jointed steel mast was raised and stepped by three seamen who came at the petty officer"s order.
Farther astern a narrow, ledge-like trapdoor of steel was raised, and from this was taken and stepped another steel jointed mast. The seamen now worked quickly in rigging aerial wires in place. In a very short time the work was completed, and the petty officer saluted von Sch.e.l.len.
"You cannot fail to understand what we are doing," hinted the young German officer.
"You are about to send or receive radio messages, I take it," Dave replied.
"You have been told, of course, that we always report our whereabouts after dark?"
"Yes, it is common knowledge with the Allies," Dave admitted. "And also that you receive instructions from the home offices of your Admiralty."
There was a crackling sound on the aerials, followed by others, some short, some long.
"A wonderful invention, is it not?" asked von Sch.e.l.len, with satisfaction.
"Yes, and first developed outside of Germany," Dave bantered, good-humoredly.
"True enough, but we have known how to take the radio and adapt it to all our needs," retorted von Sch.e.l.len.
"Your operator is now reporting your whereabouts, of course."
"That would seem likely, wouldn"t it?" the other demanded.
"And then you will receive information."
"Yes; and sometimes we have even messages for our men from their homes,"
laughed von Sch.e.l.len. "More! I have even had tender messages from my sweetheart! And have answered them in kind!"
For a moment Dave stared in astonishment. He knew von Sch.e.l.len for a truly heartless brute. The idea that any woman could love this fellow came almost as a shock. And that Sch.e.l.len could have any tender feelings!
Wonders would never cease.
"Of what are you thinking, if I may ask?" the German went on.
"After information coming to you," Darrin hinted, "it almost goes without saying that you receive your orders."
"Surely we receive them," nodded the German, "if we happen to need any.
But in our line of professional work, after we have received information we do not often need orders. We know how to use our information."
"Of course," Dave went on, "any other radio operator who is within hearing distance can pick up your messages, so you do not send them in open German but use a code, or rather, a series of codes."
"If your radio men have ever picked up any of our messages," retorted the young German, "you must know that you were not able to decipher their meaning."
"We could not always decipher them," Darrin admitted.
