"Nothing can be hurt by reserving our verdict until tomorrow," said Weber. "Obenstein is very secluded. I believe that it has neither telephone nor telegraph, and we'll surely be able to leave it tomorrow before any pursuit can reach us."

"Do you think the plan a good one?" said John to Julie.

"I know of no better," she replied in English. "I trust to you and Mr.

Weber."

"Then it's agreed," said John to Weber.

"It's agreed."

The Alsatian now led the way in his light machine, and the limousine followed at an interval of fifty or sixty yards. One hour, then two and three pa.s.sed, and nothing came in the way of their easy and rapid progress. It all seemed too smooth and fortunate to John. It was incredible that they could travel thus great distances through Austria, the land of the enemy. He knew that chance had a way of finding a balance, and violent and fierce events might be before them.

But as he drove on he scanned the heavens now and then with a questing eye. It had not occurred to him until Weber spoke that all of them might escape through the air. Lannes would trail them, not on the earth, but through mists and clouds. He would come, too, with friends almost as daring and skillful as himself, perhaps with Caumartin and the two, Castelneau and Mery, who had responded to the thrilling signal near Salzburg, when he took his first flight. His blood leaped and danced, and once more his eyes roved over the blue in search of the _Arrow._

They came to Obenstein a little before dusk. It was a tiny village, almost hidden in a recess of the mountain, with a s.h.a.ggy pine forest rising above it and casting its shadow over the houses. But there was a small, neat inn, and a garage for the machines, and the guests were received with the same hospitality that had been shown at Tellnitz. John again spread the rumor that it was a princess of the house of Auersperg who came, and he added Weber to the list of those who were attending her in her flight to a safer region. Julie withdrew as before to her room with her maid, but giving John, before she went, the brilliant smile of faith and confidence that would have sent him, sword in hand, against dragons.

He and Weber sat awhile in the little smoking-room talking in low tones of their journey. Most of the time they were alone, a waiter merely pa.s.sing through now and then, and they had no fear of being overheard.

"Weber," he said, "I've learned from the innkeeper that a mountain road leads from here toward Switzerland and I feel sure already that your suggestion about our escaping into that country is good. You, of course, when you reach the border will do as you choose, as you will want to continue the dangerous work upon which you're engaged. But you may be sure that if we do get through, Mademoiselle Lannes and I will never forget the help that you have given us."

"All that I do I do gladly," said Weber. "You may not have spoken to each other but it is easy for me to tell how matters stand between Mademoiselle Lannes and you."

John was silent but his color deepened.

"You must not mind my saying these things," said Weber, speaking easily.

"I'm older than you and the times are unusual. When you reach Paris you and Mademoiselle Lannes will be married."

John was still silent.

"And you will take her to America for the present, or at least Until the war is over. Ah, well! You're a happy man! Youth and the springtime!

Beauty and love! Kings can procure no more and seldom as much! I think I'll walk in the air a little and have a smoke."

"And I," said John, "will go to sleep. I've a tiny room on the ground floor, but it's big enough to hold me. Good night."

"Good night, Mr. Scott."

There was only a single window in John's little room, but before undressing he opened it and stood there to breathe the cool night air for a while. It looked upon the forest that ran up the slope of the mountain, and the odor of the pines was very pleasant. Looking idly at the trunks and the foliage he saw a shadow pa.s.s into the depths of the forest and something, a pulse in his temple, perhaps, struck a warning note.

A shiver ran down his back and his hair lifted, as if touched with electric sparks. Acting at once under impulse he touched the pistol inside the pocket of his jacket to see that it was all right, and slipped out of the room.

He had marked the point at which the shadow disappeared in the forest and he followed it on light foot. He had been awakened as if a stroke of lightning had blazed suddenly before his eyes, and now his brain was seething with fierce thoughts, called up by a long chain of incidents, all at once made complete.

His hand slipped again to the revolver and he drew it forth, holding it ready for instant use. Then he went forward swiftly again on noiseless steps, and once more he caught a glimpse of the flitting shadow straight ahead. He increased his speed and the shadow resolved itself into the figure of a man, a figure that seemed familiar to him.

Two or three times the man stopped and looked back, but John had shrunk behind a tree and no pursuit was visible. Then he resumed his rapid flight up the steep slope, and young Scott persistently followed, never once losing sight of the active figure.

The way led to the crest of the mountain which hung about two thousand feet above the village and it was a climb requiring some time and endurance, but though John's pulse beat fast it was with excitement and not with exhaustion. At the summit he saw the figure emerge upon an open s.p.a.ce upon which stood a slender round tower of considerable height.

John stopped at the edge of the pines and saw the figure disappear within the tower, upon the summit of which something presently began to flash and crackle. He caught his breath and the blood leaped fiercely through his veins. He knew that the tower was a wireless signal station and that it was talking to another somewhere. It sent, too, as he well knew, through the velvety blue of the night the message that Mademoiselle Julie Lannes, Suzanne, her maid, and John Scott, the American, were in the village of Obenstein where they could be taken.

He cursed himself for a fool, thrice a fool! Why had he not understood long before? Why had he not seen that so many coincidences could not be the result of chance? Only design and skill could have brought them about! Who had disabled the automobile in that flight with Carstairs and Wharton from the Germans? Who had sought to delay Lannes until he could be caught by the enemy? Who was the mysterious man in the aeroplane who had wounded Philip, who had led John from the chateau under the very rifles of the waiting marksmen, and who had been responsible for Julie's capture at Chastel? That letter, purporting to be from Philip, and directing her to come to Chastel, was surely a forgery!

These and all the other details crashed upon him with c.u.mulative force, and he was so mad with fury that he thought his heart would burst with the surging blood. Why had the man worked with such energy and such cruel persistence against him? But his wonder quickly pa.s.sed, because the reason did not matter now. Instead he put his finger on the trigger of the automatic and waited.

The wireless flashed and crackled for five minutes, then five minutes of silence and the figure of Weber reappeared at the base of the tower. He lingered there for a little s.p.a.ce looking warily about him, before he began the descent of the mountain, and John quietly withdrew further into the pines. Weber presently crossed the open s.p.a.ce, entering the forest, and John, noiseless, retreated before him.

Thus they proceeded down the mountain until the wireless tower was left several hundred yards behind and they were buried deep in the pine forest. Then John stepped suddenly into the road not twenty yards before the Alsatian and leveling his automatic said sharply:

"Hands up, Weber!"

Weber started violently and slowly raised his hands. But he said with composure:

"Why this sudden violence, Mr. Scott?"

"Because you have been upon the wireless tower signaling to our enemies. I've just understood everything, Weber. You're a German and not a French spy, and you've played the traitor to Julie and Philip Lannes and me all along."

There was enough moonlight for John to see that Weber's face was distorted by an evil smile.

"You've been a trifle slow in discovering just what I am," he said, calmly. "I've wondered that a young man of your perception didn't find me out earlier."

John flushed. The Alsatian's effrontery, in truth, had been amazing and in that perhaps lay his success--so far.

"It's true," he said, "I should have suspected you sooner, but it did not occur to me that human nature could be so vile. To undertake such risks and to use so much trickery and guile there must be a powerful motive, and in your case I can't guess it. Now, Weber, why did you do it?"

"Let me drop my hands, Mr. Scott, and I'll answer you," said Weber.

"It's difficult to argue a case in such a strained and awkward position."

"Put them down, then, but remember that I'm watching you, and that I'm willing to shoot. Now, go ahead. Why have you been such a persistent enemy of Mademoiselle Lannes, her brother and myself? Why have you been such a triple traitor?"

"Don't call me a traitor, because a traitor I am not. On the contrary I am loyal with a loyalty of which you, John Scott, an American, know nothing. I've called myself an Alsatian, but really I am not. I am an Austrian. I was born on the Zillenstein estate of Prince Karl of Auersperg. My family has served his for a thousand years. Great as I hold Hapsburg and Hohenzollern, Auersperg means even more to me. The Auerspergs are the very essence and spirit of that aristocracy and rule of the very highborn, in which I believe and to which your country and later the French have stood in the exact opposite. Every time that my pulse beats within me it beats with the wish that you and all that you stand for should fail."

John did not feel the slightest doubt of Weber's sincerity. The increasing moonlight, falling in a silver flood across his face, showed too clearly his earnestness. Yet that earnestness was not good to look upon. It was sinister, tinged strongly with the beliefs of an old and wicked past. He too, like his master, was of the Middle Ages.

"And so in all these deeds you were serving Prince Karl of Auersperg?"

said John.

"To the death. It was a false escape that I planned for you at the chateau. You were to have been shot down, but by an unlucky chance you escaped in the water."

"I've surmised that already."

"I'm an aviator, not so great as your friend Lannes, but no mean one nevertheless. It was I who pursued him, when you were with him in the _Arrow_ near Paris, and wounded him."

"I've surmised that, too."

"And when Prince Karl coveted Mademoiselle Julie Lannes--and I do not blame him--I was of the most help to him in that matter so near to his heart. Do you understand that it was a great honor he offered Mademoiselle Lannes, to make her his morganatic wife? He need not have offered her so much."

The great pulse in John's throat beat heavily and his hand pressed the automatic, but he compressed his lips and said nothing.
