Then McKay's sunken eyes glittered and he stiffened up, and his wasted features seemed to shrink until the parting of his lips showed his teeth. It was a dreadful laughter--his manner, now, of expressing mirth.

"Recklow," he said, "in 1914 that vast enterprise was scheduled to be finished according to plan. With the declaration of war in August the Hun was to have blasted his way to the surface of French soil behind the barrier forts! He was prepared to do it in half an hour's time.

"Do you understand? Do you see how it was planned? For forty-eight years the Hun had been preparing to seize France and crush Europe.

"When the Hun was ready he murdered the Austrian archduke--the most convenient solution of the problem for the Hun Kaiser, who presented himself with the pretext for war by getting rid of the only Austrian with whom he couldn't do business."

Again McKay laughed, silently, showing his discoloured teeth.

"So the archduke died according to plan; and there was war--according to plan. And then, Recklow, G.o.d'S HAND MOVED!--very slightly--indolently--scarcely stirring at all.... A drop of icy water percolated the limestone on Mount Terrible; other drops followed; linked by these drops a thin stream crept downward in the earth along the limestone fissures, washing away glacial sands that had lodged there since time began."... He leaned forward and his brilliant, sunken eyes peered into Recklow's:

"Since 1914," he said, "the Staubbach has fallen into the bowels of the earth and the Hun has been fighting it miles under the earth's surface.

"They can't operate from the glacier on the white Shoulder of Thusis; whenever they calk it and plug it and stop it with tons of reinforced waterproof concrete--whenever on the surface of the world they dam it and turn it into new channels, it evades them. And in a new place its icy water bursts through--as though every stratum in the Alps dipped toward their underground tunnel to carry the water from the Glacier of Thusis into it!"

He clenched his wasted hands and struck the table without a sound:

"G.o.d blocks them, d.a.m.n them!" he said in his ghost of a voice. "G.o.d bars the Boche! They shall not pa.s.s!"

He leaned nearer, twisting his clenched fingers together: "We saw them, Recklow. We saw the Staubbach fighting for right of way; we saw the Hun fighting the Staubbach--Darkness battling with Light!--the Hun against the Most High!--miles under the earth's crust, Recklow.... Do you believe in G.o.d?"

"Yes."

"Yes.... We saw Him at work--that young girl asleep there, and I--month after month we watched Him check and dismay the modern Pharaoh--we watched Him countermine the Nibelungen and mock their filthy Gott! And Recklow, we laughed, sometimes, where laughter among clouded minds means nothing--nothing even to the Hun--nor causes suspicion nor brings punishment other than the accustomed kick and blow which the Hun reserves for all who are helpless."...

He bowed his head in his hands. "All who are weak and stricken," he whispered to himself.

Recklow said: "Did they harm--HER?" And,

McKay looked up at that, baring his teeth in a swift snarl:

"No--you see her clipped hair--and the thin body.... In her blouse she pa.s.sed for a boy, unquestioned, unnoticed. There were thousands of us, you see.... Some of the insane women were badly treated--all of the younger ones.... But she and I were together.... And I had my pistol in reserve--for the crisis!--always in reserve--always ready for her." Recklow nodded. McKay went on:

"We fought the Staubbach in shifts.... And all through those months of autumn and winter there was no chance for us to get away. It is not cold under ground.... It was like a dark, thick dream. We tried to realise that war was going on, over our heads, up above us somewhere in daylight--where there was sun and where stars were....

It was like a thick dream, Recklow. The stars seemed very far...."

"You had pa.s.sed as inmates of some German asylum?"

"We had killed two landwehr on the Staubbach. That was a year ago last August--" He looked at the sleeping girl beside him: "My little comrade and I undressed the swine and took their uniforms....

After a long while--privations had made us both light-headed I think--we saw a camp of the insane in the woods--a fresh relay from Mulhaus. We talked with their guards--being in Landwehr uniform it was easy. The insane were clothed like miners. Late that night we exchanged clothes with two poor, demented creatures who retained sufficient reason, however, to realise that our uniforms meant freedom.... They crept away into the forest. We remained.... And marched at dawn--straight into the jaws of the Great Secret!"

Recklow had remained at the telephone until dawn. And now Belfort was through with him and Verdun understood, and Paris had relayed to Headquarters and Headquarters had instructed John Recklow.

Before Recklow went to bed he parted his curtain and looked out at the misty dawn.

In the silvery dusk a c.o.c.k-pheasant was crowing somewhere on a wheat-field's edge. A barnyard chanticleer replied. Clear and truculent rang out the challenge of the Gallic c.o.c.k in the dawn, warning his wild neighbour to keep to the wilds. So the French trumpets challenge the shrill, barbaric fanfares of the Hun, warning him back into the dull and shadowy wilderness from whence he ventured.

Recklow was awake, dressed, and had breakfasted by eight o'clock.

McKay, in his little chamber on the right, still slept. Evelyn Erith, in the tiny room on the left, slept deeply.

So Recklow went out into his garden, opened the wooden door in the wall, seated himself, lighted his pipe, and watched the Belfort road.

About ten o'clock two American electricians came buzzing up on motor-cycles. Recklow got up and went to the door in the wall as they dismounted. After a short, whispered consultation they guided their machines into the garden, through a paved alley to a tiled shed. Then they went on duty, one taking the telephone in Recklow's private office, the other busying himself with the clutter of maps and papers. And Recklow went back to the door in the wall. About eleven an American motor ambulance drove up. A nurse carrying her luggage got out, and Recklow met her.

After another whispered consultation he picked up the nurse's luggage, led her into the house, and showed her all over it.

"I don't know," he said, "whether they are too badly done in to travel as far as Belfort. There'll be a Yankee regimental doctor here to-day or to-morrow. He'll know. So let 'em sleep. And you can give them the once-over when they wake, and then get busy in the kitchen."

The girl laughed and nodded.

"Be good to them," added Recklow. "They'll get crosses and legions enough but they've got to be well to enjoy them. So keep them in bed until the doctor comes. There are bathrobes and things in my room."

"I understand, sir."

"Right," said Recklow briefly. Then he went to his room, changed his clothes to knickerbockers, his shoes for heavier ones, picked up a rifle, a pair of field-gla.s.ses and a gas-mask, slung a satchel containing three days' rations over his powerful shoulders, and went out into the street.

Six Alpinists awaited him. They were peculiarly accoutred, every soldier carrying, beside rifle, haversack and blanket, a flat tank strapped on his back like a knapsack.

Their sergeant saluted; he and Recklow exchanged a few words in whispers. Then Recklow strode away down the Belfort road. And the oddly accoutred Alpinists followed him, their steel-shod soles ringing on the pavement.

Where the Swiss wire bars the frontier no sentinels paced that noon.

This was odd. Stranger still, a gap had been cut in the wire.

And into this gap strode Recklow, and behind him trotted the nimble blue-devils, single file; and they and their leader took the ascending path which leads to the Calvary on Mount Terrible.

Standing that same afternoon on the rocks of that grim Calvary, with the weatherbeaten figure of Christ towering on the black cross above them, Recklow and his men gazed out across the tumbled mountains to where the White Shoulder of Thusis gleamed in the sun.

Through their gla.s.ses they could sweep the glacier to its terminal moraine. That was not very far away, and the "dust" from the Staubbach could be distinguished drifting out of the green ravine like a windy cloud of steam.

"Allons," said Recklow briefly.

They slept that night in their blankets so close to the Staubbach that its wet, silvery dust powdered them, at times, like snow.

At dawn they were afield, running everywhere over the rocks, searching hollows, probing chasms, creeping into ravines, and always following the torrent which dashed whitely through its limestone canon.

Perhaps the Alpine eagles saw them. But no Swiss patrol disturbed them. Perhaps there was fear somewhere in the Alpine Confederation--fear in high places.

Also it is possible that the bellowing bl.u.s.ter of the guns at Metz may have allayed that fear in high places; and that terror of the Hun was already becoming less deathly among the cantons of a race which had trembled under Boche blackmail for a hundred years.

However, for whatever reason it might have been, no Swiss patrols bothered the blue devils and Mr. Recklow.

And they continued to swarm over the Alpine landscape at their own convenience; on the Calvary of Mount Terrible they erected a dwarf wireless station; a hundred men came from Delle with radio-impedimenta; six American airmen arrived; American planes circled over the northern border, driving off the squadrilla of Count von Dresslin.

And on the second night Recklow's men built fires and camped carelessly beside the brilliant warmth, while "mountain mutton"

frizzled on pointed sticks and every blue-devil smacked his lips.

On the early morning of the third day Recklow discovered what he had been looking for. And an Alpinist signalled an airplane over Mount Terrible from the White Shoulder of Thusis. Two hours later a full battalion of Alpinists crossed Mount Terrible by the Neck of Woods and exchanged flag signals with Recklow's men. They had with them a great number of cylinders, coils of wire, and other curious-looking paraphernalia.

When they came up to the ravine where Recklow and his men were grouped they immediately became very busy with their cylinders, wires, hose-pipes, and other instruments.
