"Perceive!" he said, breaking it open and showing the kernel. "Has human eye ever before seen it?" He thrust it into Marie's open mouth. "And it is gone! _Voila tout_!"

It was that evening, while Sara Lee cut bandages and Henri rolled them, that she asked him what his work was. He looked rather surprised, and rolled for a moment without replying. Then: "I am a man of all work,"

he said. "What you call odd jobs."

"Then you don't do any fighting?"

"In the trenches--no. But now and then I have a little skirmish."

A sort of fear had been formulating itself in Sara Lee's mind. The trenches she could understand or was beginning to understand. But this alternately joyous and silent idler, this soldier of no regiment and no detail--was he playing a man's part in the war?

"Why don't you go into the trenches?" she asked with her usual directness.

"You say there are too few men. Yet--I can understand Monsieur Jean, because he has only one eye. But you!"

"I do something," he said, avoiding her eyes. "It is not a great deal.

It is the thing I can do best. That is all."

He went away some time after that, leaving the little house full and busy justifying its existence. The miller's son, who came daily to chat with Marie, was helping in the kitchen. By the warm stove, and only kept from standing over it by Marie's sharp orders, were as many men as could get near. Each held a bowl of hot soup, and--that being a good day--a piece of bread. Tall soldiers and little ones, all dirty, all weary, almost all smiling, they peered over each other's shoulders, to catch, if might be, a glimpse of Marie's face.

When they came too close she poked an elbow into some hulking fellow and sent him back.

"Elbow-room, in the name of G.o.d," she would beg.

Over all the room hung the warm steam from the kettles, and a delicious odor, and peace.

Sara Lee had never heard of the word _morale_. She would have been astonished to have been told that she was helping the _morale_ of an army. But she gave each night in that little house of mercy something that nothing else could give--warmth and welcome, but above all a touch of home.

That night Henri did not come back. She stood by her table bandaging, washing small wounds, talking her bits of French, until one o'clock.

Then, the last dressing done, she went to the kitchen. Marie was there, with Maurice, the miller's son.

"Has the captain returned?" she asked.

"Not yet, mademoiselle."

"Leave a warm fire," Sara Lee said. "He will probably come in later."

Maurice went away, with a civil good night. Sara Lee stood in the doorway after he had gone, looking out. Farther along the line there was a bombardment going on. She knew now what a bombardment meant and her brows contracted. Somewhere there in the trenches men were enduring that, while Henri--

She said a little additional prayer that night, which was that she should have courage to say to him what she felt--that there were big things to do, and that it should not all be left to these smiling, ill-clad peasant soldiers.

At that moment Henri, in his gray-green uniform, was cutting wire before a German trench, one of a party of German soldiers, who could not know in the darkness that there had been a strange addition to their group.

Cutting wire and learning many things which it was well that he should know.

Now and then, in perfect German, he whispered a question. Always he received a reply. And stowed it away in his tenacious memory for those it most concerned.

At daylight he was asleep by Sara Lee's kitchen fire. And at daylight Sara Lee was awakened by much firing, and putting on a dressing gown she went out to see what was happening. Rene was in the street looking toward the poplar trees.

"An attack," he said briefly.

"You mean--the Germans?"

"Yes, mademoiselle."

She went back into the little ruined house, heavy-hearted. She knew now what it meant, an attack. That night there would be ambulances in the street, and word would come up that certain men were gone--would never seek warmth and shelter in her kitchen or beg like children for a second bowl of soup.

On the kitchen floor by the dying fire Henri lay asleep.

XIII

Much has been said of the work of spies--said and written. Here is a woman in Paris sending forbidden messages on a marked coin. Men are tapped on the shoulder by a civil gentleman in a sack suit, and walk away with him, never to be seen again.

But of one sort of spy nothing has been written and but little is known.

Yet by him are battles won or lost. On the intelligence he brings attacks are prepared for and counter-attacks launched. It is not always the airman, in these days of camouflage, who brings word of ammunition trains or of new batteries.

In the early days of the war the work of the secret service at the Front was of the gravest importance. There were fewer air machines, and observation from the air was a new science. Also trench systems were incomplete. Between them, known to a few, were breaks of solid land, guarded from behind. To one who knew, it was possible, though dangerous beyond words, to cross the inundated country that lay between the Belgian Front and the German lines, and even with good luck to go farther.

Henri, for instance, on that night before had left the advanced trench at the railway line, had crawled through the Belgian barbed wire, and had advanced, standing motionless as each star sh.e.l.l burst overhead, and then moving on quickly. The inundation was his greatest difficulty.

Shallow in most places, it was full of hidden wire and crisscrossed with irrigation ditches. Once he stumbled into one, but he got out by swimming. Had he been laden with a rifle and equipment it might have been difficult.

He swore to himself as his feet touched ground again. For a star sh.e.l.l was hanging overhead, and his efforts had sent wide and ever increasingly widening circles over the placid surface of the lagoon. Let them lap to the German outposts and he was lost.

Henri's method was peculiar to himself. Where there was dry terrain he did as did the others, crouched and crept. But here in the salt marshes, where the sea had been called to Belgium's aid, he had evolved a system of moving, neck deep in water, stopping under the white night lights, advancing in the darkness. There was no shelter. The country was flat as a hearth.

He would crawl out at last in the darkness and lie flat, as the dead lie.

And then, inch by inch, he would work his way forward, by routes that he knew. Sometimes he went entirely through the German lines, and reconnoitered on the roads behind. They were shallow lines then, for the inundation made the country almost untenable, and a charge in force from the Belgians across was unlikely.

Henri knew his country well, as well as he loved it. In a farmhouse behind the German lines he sometimes doffed his wet gray-green uniform and put on the clothing of a Belgian peasant. Trust Henri then for being a lout, a simple fellow who spoke only Flemish--but could hear in many tongues. Watch him standing at crossroads and marveling at big guns that rumble by.

At first Henri had wished, having learned of an attack, to be among those who repelled it. Then one day his King had sent for him to come to that little village which was now his capital city.

He had been sent in alone and had found the King at the table, writing.

Henri bowed and waited. They were not unlike, these two men, only Henri was younger and lighter, and where the King's eyes were gray Henri's were blue. Such a queer setting for a king it was--a tawdry summer home, ill-heated and cheaply furnished. But by the presence of Belgium's man of all time it became royal.

So Henri bowed and waited, and soon the King got up and shook hands with him. As a matter of fact they knew each other rather well, but to explain more would be to tell that family name of Henri's which must never be known.

"Sit down," said the King gravely. And he got a box of cigars from the mantelpiece and offered it. "I sent for you because I want to talk to you. You are doing valuable work."

"I am glad you think it so, sire," said Henri rather unhappily, because he felt what was coming. "But I cannot do it all the time. There are intervals--"

An ordinary mortal may not interrupt a king, but a king may interrupt anything, except perhaps a German bombardment.

"Intervals, of course. If there were not you would be done in a month."

"But I am a soldier. My place is--"

"Your place is where you are most useful."
