succeed in making any impression upon his companion, who with a yawn that threatened to dislocate his jaws replied: "Perhaps you are right; but I am going to bed. This need not prevent you from searching around, however; and if you find anything you can wake me."

Lecoq made no sign of impatience: nor in reality was he impatient. These words afforded him the opportunity for which he was longing. "You will give me a moment first," he remarked. "In five minutes, by your watch, I promise to let you put your finger on the mystery that I suspect here."

"Well, go on for five minutes."

"After that you shall be free, Father Absinthe. Only it is clear that if I unravel the mystery alone, I alone ought to pocket the reward that a solution will certainly bring."

At the word "reward" the old police agent pricked up his ears. He was dazzled by the vision of an infinite number of bottles of the greenish liquor whose name he bore. "Convince me, then," said he, taking a seat upon a stool, which he had lifted from the floor.

Lecoq remained standing in front of him. "To begin with," he remarked, "whom do you suppose the person we have just arrested to be?"

"A porter, probably, or a vagabond."

"That is to say, a man belonging to the lowest class of society: consequently, a fellow without education."

"Certainly."

Lecoq spoke with his eyes fixed upon those of his companion. He distrusted his own powers, as is usual with persons of real merit, but he felt that if he could succeed in making his convictions penetrate his comrade's obtuse mind, their exactitude would be virtually proved.

"And now," he continued, "what would you say if I showed you that this young man had received an excellent, even refined, education?"

"I should reply that it was very extraordinary. I should reply that—but what a fool I am! You have not proved it to me yet."

"But I can do so very easily. Do you remember the words that he uttered as he fell?"

"Yes, I remember them perfectly. He said: 'It is the Prussians who are coming.'"

"What do you suppose he meant by that?"

"What a question! I should suppose that he did not like the Prussians, and that he supposed he was offering us a terrible insult."

Lecoq was waiting anxiously for this response. "Ah, well; Father Absinthe," he said gravely, "you are wrong, quite wrong. And that this man has an education superior to his apparent position is proved by the fact that you did not understand his meaning, nor his intention. It was this single phrase that enlightened me."

Father Absinthe's physiognomy expressed the strange and comical perplexity of a man who is so thoroughly mystified that he knows not whether to laugh, or to be angry. After reflecting a little, he decided to adopt the latter course. "You are rather too young to impose upon an old fellow like me," he remarked. "I don't like boasters—"

"One moment!" interrupted Lecoq; "allow me to explain. You have certainly heard of a terrible battle which resulted in one of the greatest defeats that ever happened to France—the battle of Waterloo?"

"I don't see the connection—"

"Answer, if you please."

"Yes—then! I have heard of it!"

"Very well; you must know then that for some time victory seemed likely to rest with the banners of France. The English began to fall back, and the emperor had already exclaimed: 'We have them!' when suddenly on the right, a little in the rear, a large body of troops was seen advancing. It was the Prussian army. The battle of Waterloo was lost."

In all his life, worthy Father Absinthe had never made such a strenuous effort to understand anything. In this case his perseverance was not wholly useless, for, springing from his stool, and probably in much the same tone that Archimedes cried "Eureka!" he exclaimed, "I understand. The man's words were only an allusion."

"It is as you have said," remarked Lecoq, approvingly. "But I had not finished. If the emperor was thrown into consternation by the appearance of the Prussians, it was because he was momentarily expecting the arrival of one of his own generals from the same direction—Grouchy—with thirty-five thousand men. So if this man's allusion was exact and complete, he was not expecting an enemy, but a friend. Now draw your own conclusions."

Father Absinthe was amazed but convinced: and his eyes, heavy with sleep a few moments before, now opened to their widest extent. "Good heavens!" he murmured, "if you put it in that way! But I forget; you must have seen something as you were looking through the shutters."

The young man shook his head. "Upon my honor," he declared, "I saw nothing save the struggle between the murderer and the poor devil dressed as a soldier. It was that sentence alone that aroused my attention."

"Wonderful! prodigious!" exclaimed the astonished old man.

"I will add that reflection has confirmed my suspicions. I ask myself why this man, instead of flying at once, should have waited and remained there, at that door, to parley with us."

With a bound, Father Absinthe sprang again to his feet. "Why?" he interrupted; "because he had accomplices, and he wished to give them time to escape. Ah! I understand it all now."

A triumphant smile parted Lecoq's lips. "That is what I said to myself," he replied, "and now it is easy to verify my suspicions. There is snow outside, isn't there?"

It was not necessary to say any more. The elder officer seized the light, and followed by his companion, he hastened to the back door of the house, which opened into a small garden. In this sheltered enclosure the snow had not melted, and upon its white surface the dark stains of numerous footprints presented themselves. Without hesitation, Lecoq threw himself upon his knees in the snow; he rose again almost immediately. "These indentations were not made by the men's feet," said he. "There have been women here."
