"How, in G.o.d's name, know you that?"

"You have been betrayed, Monsieur. Your plan is known. You leave the house to-night, near a quarter of eleven, to go in secret to the king.

You leave by the little door in the alley--"

"Diable!" breathed Vigo.

"They set on you on your way--three of them--to run you through before you can draw."

"But, ventre bleu! Monsieur is not alone."

"No; he walks between you and M. Lucas."

Not one of them spoke. They stared at me as if I were something uncanny.

I, a raw country boy, disclosing a perfect knowledge of their most intimate plans!

"How know you this?" Monsieur demanded of me. But he was not looking at me. His keen glance went first to Lucas, then to Vigo, the two men who had shared his confidence. The secretary cried out:

"You cannot think, Monsieur, that I betrayed you?"

Vigo said nothing. His steady eyes never left Monsieur's face.

"No," answered Monsieur to Lucas, "I cannot think it." And to Vigo he said: "I shall accuse you when I accuse myself. But--none knew this thing save our three selves." And his gaze went back to Lucas.

"It is not likely to be he," I said, impelled to be just to him though I did not like him, "for they meant to kill him as well."

Lucas started, then instantly recovered himself.

"A comprehensive plot, Monsieur," he said, with a smile.

"Then who was it?" cried Monsieur to me. "You know. Speak."

"There is a spy in the house--an eavesdropper," I said, and then paused.

"Aye?" said Monsieur. "Who?"

Now the answer to this was easy, yet I flinched before it; for I knew well enough what Monsieur would do. He feared no man, and waited on no man's advice. And if he was a good lover, he was a good hater. He would not inform the governor, and await the tardy course of justice, that would probably accomplish--nothing. Nor would he consider the troubled times and the danger of his position, and ignore the affair, as many would have deemed best. He would not stop to think what the Sixteen might have to say to it. No; he would call out his guards and slay the plotters in the Rue Coupejarrets like the wolves they were. It was right he should, but--I owed my life to Yeux-gris.

"His name, man, his name!" Monsieur was crying.

"Monsieur," I returned, flushing hot, "Monsieur--"

"Do you know his name?"

"Yes, Monsieur, I know his name, but--"

Monsieur looked at me in surprise and frowning, impatience. Quickly Lucas struck in:

"Monsieur, I have grave doubts of the boy's honesty."

"Doubts!" cried Monsieur, with a sudden laugh. "It is not a case for doubts. The boy states facts."

He seated himself in his chair, his face growing stern again. The little action seemed to make him no longer merely my questioner, but my judge.

"Now, Felix Broux, let us get to the bottom of this."

"Monsieur," I began, struggling to put the case clearly, "I learned of the plot by accident. I did not guess for a long time it was you who were the victim. When I found out that, I came straight here to you.

Monsieur, there are four men in the plot, and one of them has stood my friend."

"And my a.s.sa.s.sin!"

"He is a black-hearted villain!" I acknowledged. "For he swore no harm was meant to you. He swore it was only a private grudge against M.

Lucas. But when one of them let out the truth I came straight to you."

"That is likely true," said Vigo, "for he was ready to kill the men who barred his way."

"You were in a plot to kill my secretary!"

"Ah, Monsieur!" I cried.

"You--Felix Broux!"

I curled with shame.

"M. Lucas had struck me," I muttered; "I thought the fight was fair enough. And they threatened my life."

Monsieur's contemptuous eyes shrivelled me as flame shrivels a leaf.

"You--a Broux of St. Quentin!"

Lucas, who had watched me close all the while, as they all three did, said now:

"I believe he is a cheat, Monsieur. There is no plot. He has learned of your plan through the eavesdropper he speaks of and thinks to make credit out of a trumped-up tale of murder."

"No," answered Monsieur. "You may think that, Lucas, for he is a stranger to you. But I know him. He was a fool sometimes, but he was never dishonest. You used to be fond of me, Felix. What has happened to make you consort with my enemies?"

"Ah, Monsieur, I love you. I have always loved you," I cried. "I am not lying now, nor cheating you. There is a plot. I learned it and came straight to you, though I was under oath not to betray them."

"Then, in Heaven's name, Felix," burst out Vigo, "which side are you on?"

Monsieur began to laugh.

"That is what I should like to know. For, by St. Quentin, I can make nothing of it."

"Monsieur," insisted Lucas, "whatever he was once, I believe him a trickster now."

Monsieur bent his keen eyes on me.

"No; he is plainly in earnest. Therefore with patience I look to get some sense out of this snarl of a story. Something is there we have not yet fathomed."
