“We’ll see where they go,” he whispered, and then laid his finger on his lips. Amusement sounded in his voice; indeed it was impossible not to perceive the humor of the position, when I felt the Cardinal’s Necklace against my own ribs.

We were walking now under cover of the trees which lined the sides of the path, so that no backward glance could discover us to the thieves; and I was wondering how long we were thus to dog their steps, when suddenly they turned to the left about fifty yards short of the spot where old Jean’s cottage stood, and disappeared from our sight. We emerged into the path, the duke taking the lead. He was walking more briskly now, and I saw him examine his pistol. When we came where the fellows had turned, we followed in their track.

The first distant hint of approaching morning caught the tops of the trees above us, turning them from black to a deep chill gray, as we paused to listen. Our pursuit had brought us directly behind the cottage, which now stood about a hundred yards on the right; and then we came upon them—or rather suddenly stopped and crouched down to avoid coming upon them—where they were squatting on the ground with a black iron box between them, and the lantern’s light thrown on the keyhole of the box. Lafleur held the lantern; Pierre’s hand was near the lock, and I presumed—I could not see—that he held some instrument with which he meant to open it. A ring of trees framed the picture, and the men sat in a hollow, well hidden from the path even had it been high day.

The Duke of Saint-Maclou touched my arm, and I leaned forward to look in his face. He nodded, and, brushing aside the trees, we sprang out upon the astonished fellows. Fora moment they did not move, struck motionless with surprise, while we stood over them, pistols in hand. We had caught them fair and square. Expecting no interruption, they had guarded against none. Their weapons were in their pockets, their hands busy with their job. They sprang up the next moment; but the duke’s muzzle covered Lafleur, and mine was leveled full at Pierre. A second later Lafleur fell on his knees with a cry for mercy; the little man stood quite still, his arms by his side and the iron box hard by his feet. Lafleur’s protestations and lamentations began to flow fast. Pierre shrugged his shoulders. The duke advanced, and I kept pace with him.

“Keep your eye on that fellow, Mr. Aycon,” said the duke; and then he put his left hand in his pocket, took out a key and flung it in Lafleur’s face. It struck him sharply between the eyes, and he whined again.

“Open the box,” said the duke. “Open it—do you hear? This instant!”

With shaking hands the fellow dragged the box from where it lay by Pierre’s feet, and dropping on his knees began to fumble with the lock. At last he contrived to unlock it, and raised the lid. The duke sprang forward and, catching him by the nape of the neck, crammed his head down into the box, bidding him, “Look—look—look!” And while he said it he laughed, and took advantage of Lafleur’s posture to give him four or five hearty kicks.

“It’s empty!” cried Lafleur, surprise rescuing him for an instant from the other emotions to which his position gave occasion. And, as he spoke, for the first time Pierre started, turning an eager gaze toward the box.

“Yes, it’s empty,” said the duke. “The necklace isn’t there, is it? Now, tell me all about it, or I’ll put a bullet through your head!”

Then the story came: disentangled from the excuses and prayers, it was simply that Pierre was no footman but a noted thief—that he had long meditated an attack on the Cardinal’s Necklace; had made Lafleur’s acquaintance in Paris, corrupted his facile virtue, and, with the aid of forged testimonials, presented himself in the character in which I had first made his acquaintance. The rascals had counted on the duke’s preoccupation with Marie Delhasse for their opportunity. The duke smiled to hear it. Pierre listened to the whole story without a word of protest or denial; his accomplice’s cowardly attempt to present him as the only culprit gained no more notice than another shrug and a softly muttered oath. “Destiny,” the little man seemed to say in the eloquent movement of his shoulders; while the growing light showed his beady eyes fixed, full and unfaltering, on me.
