The pa.s.sing and repa.s.sing shadows of craft gave a fitful l.u.s.ter to the river; so crisply white were the spanning highways that the eye grew quickly dim with looking; the brisk channel breeze which moved with rough gaiety through the trees in the gardens of the Tuileries, had, long hours before, blown away the storm. Bright sunshine, expanses of deep cerulean blue, towering banks of pleasant clouds, these made Paris happy to-day, in spots.

The great minister gazed across the river, his hands under the tails of his frock, and the perturbation of his mind expressed by the frequent flapping of those somber woolen wings. To the little man who watched him, there was a faint resemblance to a fiddling cricket.

"Sometimes I am minded to trust the whole thing to luck, and bother no more about him."

"Monsieur, I have obeyed orders for seven years, since we first recognized the unfortunate affair. Nothing he has done in this period is missing from my notebook; and up to the present time he has done--nothing. But just a little more patience. This very moment, when you are inclined to drop it, may be the one. One way or another, it is a matter of no real concern to me. There will always be plenty of work for me to do, in France, or elsewhere. But I am like an old soldier whose wound, twinging with rheumatism, announces the approach of damp weather. I have, then, monsieur, a kind of psychological rheumatism; prescience, bookmen call it. Presently we shall have damp weather."

"You speak with singular conviction."

"In my time I have made very few mistakes. You will recollect that.

Twenty years have I served France. I was wrong to say that this affair does not concern me. I'm interested to see the end."

"But will there be an end?" impatiently. "If I were certain of that!

But seven years, and still no sign."

"Monsieur, he is to be feared; this inactivity, to my mind, proves it.

He is waiting; the moment is not ripe. There are many sentimental fools in this world. One has only to step into the street and shout 'Down with!' or 'Long live!' to bring these fools clattering about."

"That is true enough," flapping the tails of his coat again.

"This fellow was born across the Rhine. He has served in the navy; he is a German, therefore we can not touch him unless he commits some overt act. He waits; there is where the danger, the real danger, lies.

He waits; and it is his German blood which gives him this patience. A Frenchman would have exploded long since."

"You have searched his luggage and his rooms, times without number."

"And found nothing; nothing that I might use effectively. But there is this saving grace; he on his side knows nothing."

"I would I were sure of that also. Eh, well; I leave the affair in your hands, and they are capable ones. When the time comes, act, act upon your own initiative. In this matter we shall give no accounting to Germany."

"No, because what I do must be done secretly. It will not matter that Germany also knows and waits. But this is true; if we do not circ.u.mvent him, she will make use of whatever he does."

"It has its whimsical side. Here is a man who may some day blow up France, and yet we can put no hand on him till he throws the bomb."

"But there is always time to stop the flight of the bomb. That shall be my concern; that is, if monsieur is not becoming discouraged and desires me to occupy myself with other things. I repeat: I have rheumatism, I apprehend the damp. He will go to America."

"Ah! It would be a very good plan if he remained there."

The little man did not reply.

"But you say in your reports that you have seen him going about with some of the Orleanists. What is your inference there?"

"I have not yet formed one. It is a bit of a riddle there, for the crow and the eagle do not fly together."

"Well, follow him to America."

"Thanks. The pay is good and the work is congenial." The tone of the little man was softly given to irony.

Gray-haired, rosy-cheeked, a face smooth as a boy's, twinkling eyes behind spectacles, he was one of the most astute, learned, and patient of the French secret police. And he did not care the flip of his strong brown fingers for the methods of Vidocq or Lecoq. His only disguise was that not one of the criminal police of the world knew him or had ever heard of him; and save his chief and three ministers of war--for French cabinets are given to change--his own immediate friends knew him as a b.u.t.terfly hunter, a searcher for beetles and scarabs, who, indeed, was one of the first authorities in France on the subjects: Anatole Ferraud, who went about, hither and thither, with a little red b.u.t.ton in his b.u.t.tonhole and a tongue facile in a dozen languages.

"Very well, monsieur. I trust that in the near future I may bring you good news."

"He will become nothing or the most desperate man in Europe."

"Admitted."

"He is a scholar, too."

"All the more interesting."

"As a student in Munich he has fought his three duels. He has been a war correspondent under fire. He is a great fencer, a fine shot, a daring rider."

"And penniless. What a country they have over there beyond the Rhine!

He would never have troubled his head about it, had they not harried him. To stir up France, to wound her if possible! He will be a man of great courage and resource," said the secret agent, drawing the palms of his hands together.

"In the end, then, Germany will offer him money?"

"That is the possible outlook."

"But, suppose he went to work on his own responsibility?"

"In that case one would be justified in locking him up as a madman. Do you know anything about Alpine b.u.t.terflies?"

"Very little," confessed the minister.

"There is often great danger in getting at them; but the pleasure is commensurate."

"Are there not rare b.u.t.terflies in the Amazonian swamps?" cynically.

"Ah, but this man has good blood in him; and if he flies at all he will fly high. Think of this man fifty years ago; what a possibility he would have been! But it is out of fashion to-day. Well, monsieur, I must be off. There is an old ma.n.u.script at the Bibliotheque I wish to inspect."

"Concerning this matter?"

"b.u.t.terflies," softly; "or, I should say, chrysalides."

The subtle inference pa.s.sed by the minister. There were many other things to-ing and fro-ing in the busy corridors of his brain. "I shall hear from you frequently?"

"As often as the situation requires. By the way, I have an idea. When I cable you the word b.u.t.terfly, prepare yourself accordingly. It will mean that the bomb is ready."

"Good luck attend you, my savant," said the minister, with a friendliness which was deep and genuine. He had known Monsieur Ferraud in other days. "And, above all, take care of yourself."

"Trust me, Count." And the secret agent departed, to appear again in these chambers only when his work was done.

"A strange man," mused the minister when he was alone. "A still stranger business for a genuine scholar. Is he really poor? Does he do this work to afford him ease and time for his studies? Or, better still, does he hide a great and singular patriotism under b.u.t.terfly wings? Patriotism? More and more it becomes self-interest. It is only when a foreign mob starts to tear down your house, that you become a patriot."

Now the subject of these desultory musings went directly to the Bibliotheque Nationale. The study he pursued was of deep interest to him; it concerned a b.u.t.terfly of vast proportions and kaleidoscopic in color, long ago pinned away and labeled among others of lesser brilliancy. It had cast a fine shadow in its brief flight. But the species was now extinct, at least so the historian of this particular b.u.t.terfly declared. Hybrid? Such a contingency was always possible.

"Suppose it does exist, as I and a few others very well know it does; what a fine joke it would be to see it fly into Paris! But, no. Idle dream! Still, I shall wait and watch. And now, suppose we pay a visit to Berlin and use blunt facts in place of diplomacy? It will surprise them."
