McGee no longer had any doubts concerning what was in store for these thousands upon thousands of men, but he was beginning to question the wisdom of his own move. He made no attempt to engage anyone in conversation, fearing that it would result in some officious commander ordering him to the rear.

Far ahead, against the black night sky, flashes of gunfire showed now and then, the following thunder establishing the fact that the front was within three or four hours' marching time. The gunfire, however, was not heavy, being merely the spasmodic firing incident to such nights as communiques spoke of as "calm."

After another hour of marching, McGee noticed that they were on the edge of a shattered village. Not one single wall stood intact. As he reached the center of this stark skeleton of a once happy village he saw that here the enemy had concentrated their fire. Here was a wall, standing gaunt and grim against the night sky; and over there, facing a little square, a shattered church still retained the strength to hold aloft its cross-capped steeple. The Cross ... in a broken, blood-red world!

McGee slowed his pace, gradually, and dropped from the line of march. He had considered himself fully recovered, but the last hour had sapped his small reserve of strength. He seated himself on a pile of stone in the dark corner of a protecting wall and wiped his brow. What with the long, hot march, and the steam arising from the soaked earth, he was wringing wet. The experience had served to increase his respect for these plodding doughboys who considered this as only one more night like dozens of others they had experienced.

Sitting there on the damp, cold stone, McGee considered his position.

This town, battered by sh.e.l.l fire, would be forward of any position taken up by a pursuit group. To push on would be but to retrace his steps. It would also be folly, for he had no gas mask. Sh.e.l.ls had reached this town before, and they might do so again. He was willing to take a chance with flying shrapnel, but deadly gas was something else again.

He decided, therefore, to make his way to the edge of the town, find shelter if possible, and await the coming of dawn. Daylight, he reasoned, would be certain to bring him in sight of planes from some group, operating on this front, and if he could locate a 'drome his problem would be near solution.

He made his way back along the lines of infantrymen, artillery, ambulances and wagon trains until he reached an old stone stable that had miraculously escaped destruction.

Having no light, he groped around in the black interior, seeking a place where he might spread his coat for a bed. He stumbled against a ladder, which mounted upward into the cavernous mow of a loft. He climbed the creaking rungs, found footing on the dry floor, and stopped to sniff at the odor of the few wisps of dry, musty hay scattered thinly over the rough boards. He took a step forward, stumbled over a pair of legs and landed headfirst on the stomach of another sleeper.

"Whoosh!" went the escaping breath of that truant soldier, followed by an angry outpouring of abuse.

"Say, soldier! Get your foot out of my face! What do you think this is--a football game?"

"Pipe down!" came a gruff voice from another corner. "Do you want some smart Looie to come up here and chase us out?"

McGee smiled, wondering what would be their reaction should he announce that "a Looie" was even now in their presence. Perhaps it was his duty, as an officer, to rout them out and order them to rejoin their commands, but he felt no responsibility for these men of the line, and if they were as weary and sleepy as he--and doubtless they had more reason to be--then he could hardly blame them for falling out. With the morning, he knew, these army-wise soldiers would go down the road until they found their outfits and there pour forth a plausible lie about becoming lost in the tangle and how they had searched all night for their company.

McGee knew little enough about the American infantrymen, but he did know that "for tricks that are vain" Bret Harte's famous heathen Chinee had nothing on the average soldier of the line, be he American, English, French or a black man from Senegal.

Cautiously he felt out a clear s.p.a.ce, spread his coat over the rough timbers and was soon sound asleep.

While McGee slept soundly, blissfully removed from all scenes of conflict and completely ignorant of his exact location, a midnight conference of gravest nature was taking place in the little settlement of Landres-et-St. Georges, far behind the German lines of defense.

Four thick-necked, grey-haired German officers were seated at a long table in the front room of a chateau that had been in German hands for more than three years. Candles flickered uncertainly on the table, lighting the center of the large room but leaving the corners in dim shadows.

The four officers sat stiffly erect, without comment, their eyes on the double door as though they were awaiting someone. Outside, on the stone flagging of a courtyard, sounded the heavy tread of a Prussian Guardsman walking guard before the sanctum of these "Most High" ones who sat so stolidly waiting.

The resounding footfalls of the guardsman came to a clicking halt, followed by a guttural challenge which was replied to in a softer voice.

The guardsman again took up his beat.

A moment later the door to the council room opened. A smooth-faced, blond young man stood at stiff salute in the doorway--dressed in the uniform of an English officer!

For a long minute he stood at salute while the four at the table eyed him studiously. Then the hand came down, and a quick smile spread over his face as he stepped forward into the brighter light of the room. He carried in his hand one of the swagger sticks so commonly used by English officers.

"Well, _Herr Hauptmann_," he addressed the officer at the head of the table, "do you find my disguise, and my English, sufficiently correct?"

"Correct, yes," the heavy-jowled officer replied in German, "but not pleasing, Count von Herzmann. _Himmel!_ How I hate the sight of the Englander's uniform and the sound of his thin, squeaky tongue. And I say to you again that this wild plan of yours is a fool's errand. I would forbid it, had you not gained the consent of the General Staff. I do not understand it. You are too valuable to the cause for the General Staff to permit you to take such a chance. I say again, it is a fool's errand."

Count von Herzmann smiled rea.s.suringly. "Fool's errand, _Herr Hauptmann?_" he responded in German. "Is there anything more precious to our cause than to learn just now where this next blow is to be struck? For the past ten days all of our secret operatives have sent us conflicting reports. The English and the French are too quiet on their fronts. It presages a storm. As for the Americans, we need not worry.

They are still boasting of their victory at St. Mihiel. They will not be ready to strike again before late Fall--perhaps not until Spring. We must--"

"Speak in English," interrupted one of the other officers. "Much as we hate it, we must see to it that it is perfect."

"Right you are!" von Herzmann replied with the perfect accent of a well-bred Englishman. "My three years' schooling in England was not for nothing, sir. Accent top hole, eh, what! Rawther." He smiled at his own mimicry. "I was saying," he went on, "that we must discover where the English will strike next. Victory depends upon it."

"_Ja_, _das ist richtig_" spoke up the stolid _Oberst-leutnant_, who had been listening without comment as his grey eyes, deep set under stiff, bristling eyebrows, appraised the confident von Herzmann. "_Ja_, we must learn where the swine strike next. But must it be you to take the chance? You know the cost--should you fail?"

"Quite well, sir," von Herzmann replied, smiling. "A little party in front of a firing wall with myself as the center of attraction. Ah, well! What matter. I have about played out my string of luck in the air.

Sooner or later, there must be an ending. I have a great fear that it will be the luck of some cub, fresh at the front, to bring me down. Ha!

How he would sw.a.n.k around, boasting how he brought down the great von Herzmann. Bah! Death, _Herr Hauptmann_, I do not fear in the least, but I hate the thought of a cub boasting over my bones. Besides, there are no new adventures left for me in the air. I am a little weary of it all. But this--this is new adventure and--"

"And deadly dangerous," reminded the cadaverous, thin-faced officer at the far end of the table.

"If not dangerous, it is not adventure, sir," von Herzmann replied. "Do we not all enjoy the thing that presents some hazard? Youth lives it; age thrills to the reports of it. If I fail, I fail. If I succeed, the Fatherland is well served and I've another adventure in my kit. Perhaps even another bit of iron to dangle on my coat, eh? Rawther jolly prospect, what?" He again smiled at his own mimicry, as well he might, for the accent was perfect. "But I won't fail, _Herr Hauptmann_."

He became serious as he drew some papers from the breast pocket of his well tailored, though well worn, English uniform coat which bore the marks of campaigning. "See," he said, tossing down a little black fold which the English issued to officers for identification, "I am Lieutenant Richard Larkin, R.F.C., known to his familiars as 'Buzz.'

The picture, you will notice, is my own, placed there after we had carefully removed the one of the gentleman whose uniform and identification card I am to make use of.

"This," he tossed another paper on the table, "is a pa.s.s to Paris, properly indorsed, and giving authority for refueling and repairing, if needed. Neat enough, eh? The date, unfortunately, was originally in April, but our Intelligence section has some very clever penmen and you will note that the date now appearing there is as of September the twenty-sixth, and the period of the pa.s.s is for five days."

"The twenty-sixth!" exclaimed the _Oberst-leutnant_. "So soon! That is the day after to-morrow."

"Yes. Our operative will cross the lines to-morrow evening, just before sundown, in a two-seater Nieuport. He will land just back of Montfaucon, and I will then re-cross the lines, will be set down back of Neuvilly and will then begin the great adventure. I am to be back within five days, or--" he shrugged his shoulder expressively.

One of the officers banged his fist on the table. "It is a fool's errand, I repeat, a fool's errand! If this operative, with the Americans, is back of Neuvilly, what is he doing there? Perhaps the Americans are there in force, preparing to strike here."

"Impossible!" the senior officer snorted. "Attack the Hindenburg Line?

The Americans are stupid, but not so stupid as that. We know that a few Americans are in the sector south of Vauquois Hill. They are relieving the French there. And for what reason? So that the French may be moved up in the Champagne, east of the Meuse. That is where the blow will be struck. But, even so, I have not the faith in this Operative Number Eighty-one which the High Command seems to place in him."

"He has brought us much information," one of the others reminded.

"Yes, erroneous and tardy information. Not one thing have we learned from him but what was too late to be of value. And much of it inaccurate."

"Not always," von Herzmann replied. "He brought correct and timely information concerning the movement of that new American pursuit squadron, you will recall. And but for the accursed luck that brought those French Spads upon us at the wrong time, my Circus would have potted half of them."

"Luck!" the senior officer retorted, heatedly. "You call it luck! It was luck that we did not lose you and that you got your crippled plane back across the line. But can you be sure that those Spads came upon the scene, at the right moment, by chance?"

Count von Herzmann shook his head. "No, _Herr Hauptmann_, in this war we can be sure of only one thing--death, if the war continues. It must be brought to a speedy close. Daily, now, we lose ground. It is because of this that I made the urgent request to be permitted to undertake this mission. But," he smiled expansively, "be not too fearful or alarmed. If I fail, if there be trickery in it, you shall have the privilege of avenging me."

"How do you mean, avenge you?"

"_Herr Hauptmann_, war is a world-old game, with modern applications. You have read, doubtless, how in the olden times hostages were held?"

"Yes, but--"

"It is not always effective, but it furnishes the crumb of revenge and retaliation. I am not without some fear for my safety, and because of that I will provide a hostage."

"You talk in riddles."

"Perhaps, but I give you the answer. Operative Number Eighty-one will come for me in a two-seater just at dark. But he will not be the one to take me back."
