The decision of his attitude seemed to inspire the white-haired man so patiently awaiting his reply. He crossed his legs, and, drawing up one well-shod foot, nursed its ankle in his clasped hands. He was leaning forward full of an anxious, nervous expression of attitude. It almost seemed as if his guest's judgment were to him a last straw of hope. The noble forehead was a-dew with moisture. His bushy eyebrows were sharply drawn in a great effort of concentration. His eyes, so widely simple, usually so expressive of childhood's innocence, were now full of a suffering that was almost overwhelming.

"If I had been guilty of a fraction of that of which the world accuses me could I have dared, or cared, to approach you with my latest invention, and – the other proposals? Keep that question in your mind while I talk. It is so easy to condemn, and, having condemned, reversal of judgment is well-nigh impossible. If I am guilty it is only of a patriot's devotion to the country to which I believed I owed allegiance. That, and an even greater devotion to the problems of making possible those things which seemed impossible. In not one of the problems of invention have I ever possessed a motive other than that which has inspired every engineer engaged upon naval armaments in every other country. Never in my life have I devised any weapon for the army other than the monster siege mortar. The liquid fire, the gases, the dozen and one contrivances for slaughter have found their inception in other brains than mine. I state these facts simply. You must trust them, or dismiss them, as you will. I am a marine inventor solely, except for that one weapon which was legitimate enough – the siege mortar. You, who understand the nature of marine invention, must assuredly realize that one man's brain, one man's lifetime are all too brief and limited to permit a division of his powers with any hope of success."

He paused as though offering opportunity for comment, but none was forthcoming. So he went on, his body slightly swaying to and fro, his eyes assuming a passionate fire that gave to his whole aspect an atmosphere of vigorous protest.

"I am a Pole," he went on presently. "I am a Pole, born in German Poland. My parents were poor, but we claim direct descent from the ancient royal house. Now let me make my own thoughts and feelings clear to you. I was brought up under German methods, German education. I was taught, as every child within the German Empire is taught, to believe that Germany is above and before all the nations of the world, and that, in the brief life of this earth, nothing else but German national interests matter to its people. Now mark the obvious result of such a training. I make no apology. I, beginning life in my father's little engineering shop, finding myself with an abnormal capacity for invention, seeking to make for myself and family a competence – what do I do? I place whatever ability I may possess at the service of Germany. I devote myself to discovery in the one direction in which official Germany has looked since the war of 1870.

"The next step comes quickly. It came so quickly that it well-nigh overbalanced my whole sense of proportion. The problem that appealed to me was the enormous strength of fortresses being built by our neighbors against our borders. We were doing the same against theirs. It was almost a simple problem. I said that if our fortresses were stronger than theirs, and we possessed a secret weapon which could destroy theirs, then our empire was safe from invasion for all time. So it came about that I took plans of my great siege mortars to the authorities. They were considered, and the guns were ultimately made. On experiment they proved an instantaneous success, and I was at once given rank and wealth, and ordered to work on the development of the gun-power of the Navy. It was this that converted me to marine engineering. From then onwards my career became one series of triumphs – from Germany's point of view. Till now, as you know, I have been rewarded with the revival of an old Polish title, to which by birth I am entitled, and am placed – as perhaps you do not know – in supreme command of Germany's naval construction."

There was no atmosphere of triumph in the man's manner. There was no victorious inspiration in the tones of his voice. With each word which announced the progress of his triumph an almost painful dejection seemed to settle more and more heavily upon him.

Still Ruxton refrained from comment. He knew that the vital things had yet to be told. Nor had he any desire to break up the man's train of thought. There still remained the tragedy of triumph which this man's life concealed.

The man's voice came again in level tones which had lost all light and shade. He spoke like one utterly weary in mind, heart, and body.

"If I had only known," he said, with a dreary shake of his snow-white head. "But," he added with a shrug, "I did not know. I was blinded by success, and a passionate devotion to my work." He drew a deep breath. "But I knew later. Oh, yes. I knew. The greatest triumph and the greatest disaster of my life was when I converted the paltry little coast defence submarines into the ocean-going pirates they afterwards became. But it was not until Germany declared a submarine blockade of these shores that I knew what I had done. Up to that time I had been a – German patriot. From that moment I became a simple, heart-broken human being. My legitimate engines of war had been turned against the innocent lives of a defenceless people, and when the massacre of fifteen hundred souls took place with the sinking of the Lusitania I think for the time I became demented."

He was breathing hard. His face had become almost stony in its expression. It was the face of a man who for the time is beyond all further feeling. Quite abruptly, however, he released his hold upon his foot, and ran his long fingers through his shock of white hair.

"Ach! How willingly would I have undone all I had done. I tried to resign on various pleas. Health!" He laughed, a hollow, mocking laugh. "As well try to struggle free from the strangling rope of the hangman with hands tied. To my horror I found that I belonged body and soul to Germany, and my rank and wealth was the price the country had paid for my brains. Oh, yes, I was no honored patriot serving my country. I was its bond slave, the slave of Prussian militarism. And to the end of my days that slave I must remain.

"Need I tell you of all the suffering I have since endured? No, I think not. No repentant murderer could have suffered more for his crimes than I have done. I have striven, by every possible argument, to assure myself that mine was not the blame, but no conviction has resulted. The world cannot blame more cruelly than I do myself, and yet – I am innocent of all intent.

"Throughout all the struggle I have had with my own soul no glimmer of light reached me until my daughter came to my rescue. And I think it was her woman's wit, supported by her own brave heart, which has saved me. She, in her great pity and love of humanity, started a fresh thought in the poor brain with which Providence endowed me. It surely was only a woman's mind could have conceived so simple a solution to my trouble. It was all done in one brief sentence. She said, 'The brain that can invent to destroy can invent to save.' And from that moment hope came to me."

He leant forward urgently. The veins at his temples stood out with the mental effort of the moment.

"Need I detail the result. I came to you as the only possible person to help on the work. You were selected after careful thought. I have warned you of the threat hanging over your country. Now I will show you the engines of destruction which I have been forced to perfect to complete the execution of that threat. But I have already shown you my submersible. You are now on board the constructed vessel, the development and adoption of which is the only antidote to the devilish plans of the country to which I belong, plans which are staggering in their possibilities. They are so simple, yet so vast and terrible when made against England. Listen: Germany has abandoned all other naval construction in favor of my new boat – the Submersible Dreadnought. Do you realize the type? It is a heavily armored vessel with the gun-power of the surface dreadnought, and its speed, but with all the attributes of the submarine. A fleet of nominally three hundred is being constructed. It will be larger by far. In a few years it will be possible to ring your country round with these lurking machines, each of which will be capable of engaging successfully any surface war vessel ever built, while its submarine attributes will render it practically immune from any combination of force opposed to it. Do you see? Never again will England, when at war with Germany, be able to transport her armies abroad. Never again will she be able to feed her millions of people through overseas channels. Henceforth she will be driven to peace under any conditions and her mastery of the seas will pass from her forever."

Ruxton stirred in his seat. He shifted his position. The man's words had sunk deeply.

"The submersible mercantile marine is certainly the obvious retort," he said reflectively. Then he added as an afterthought, "Temporarily."

"Yes. Temporarily."

Neither spoke again for some moments. Both were thinking ahead, much further on than the immediate future.

"And after the submersible dreadnought?" Ruxton's question was not addressed to the inventor, but it was answered by him.

"Who can tell? One of these two countries must go under."

"Yes."

Again came a prolonged silence. Again Ruxton shifted his position. Then at last he spoke.

"And you will show me these things. The risk will be stupendous – for you."

Prince Stanislaus laughed without a shadow of mirth.

"For me it is just a matter of life and death. Life has few attractions for me now. For you? My power is sufficient to safeguard you. Shall I show you how?"

Ruxton nodded. His penetrating gaze was again fixed upon the almost cadaverous features with their snow-white crown and noble forehead.

"Yes," he said.

Prince Stanislaus began at once. And talk went on between them for many minutes. For the most part Ruxton listened, as was his way, and only occasionally interpolated a shrewd, incisive question. His dark, penetrating eyes were watchful and studying. And no change of expression in the other was lost upon him.

Slowly within him there grew a wide admiration for the mentality and courage in this strangely simple creature. He read him down to the remotest depths of his honest soul. Wherever Prince Stanislaus's devotion to his life's work had led him, there was no shadow of doubt left in the Englishman's mind as to his present sincerity and honesty of purpose.

When the last detail of the plan had been explained Ruxton stood up.

"The judgment of the world is rarely inspired by justice," he said. "I thank you, and will gladly place myself under your guidance. Since the opportunity of discovering the secrets of Kiel and Cuxhaven has been vouchsafed to me I should be far less than the patriot I desire to be did I shirk the risks. My duty is quite plain."

The relief and satisfaction his words inspired in the other were obvious.

"I thank you," he said earnestly. "You have helped me to that peace which I have long sought and I had come to believe could never again be mine in this life. But – "

"But?"

The man was smiling.

"But we do not go to either Kiel or Cuxhaven."

Ruxton was startled.

"Where then?" he demanded shortly.

"To the Baltic. Mr. Farlow, you have no idea of the subtlety of the people with whom we are dealing. All eyes of the world are on Cuxhaven and Kiel. Every vulture of the foreign secret services is hovering over those places, and the forges and foundries are working to deceive them. But the real work and preparations I speak of are not being made in Germany at all. We go to the Baltic, to the island of Borga, which is off the coast of Sweden. And there we shall find under German administration a naval 'Krupps,' and the greatest arsenal in the whole world."
