Derues had succeeded in taking up an advantageous position.  If he had begun narrating the extraordinary romance he had invented, the least penetrating eye must have perceived its improbability, and one would have felt it required some support at every turn.  But since he had resisted being forced to tell it, and apparently only ceded to Monsieur de Lamotte’s violent persistency, the situation was changed; and this refusal to speak, coming from a man who thereby compromised his personal safety, took the semblance of generosity, and was likely to arouse the magistrate’s curiosity and prepare his mind for unusual and mysterious revelations.  This was exactly what Derues wanted, and he awaited the interrogation with calm and tranquillity.

“Why did you leave Paris?” the magistrate demanded a second time.

“I have already had the honour to inform you that important business necessitated my absence.”

“But you refused to explain the nature of this business.  Do you still persist in this refusal?”

“For the moment, yes.  I will explain it later.”

“Where have you been?  Whence do you return?”

“I have been to Lyons, and have returned thence.”

“What took you there?

“I will tell you later.”

“In the month of December last, Madame de Lamotte and her son came to Paris?

“That is so.”

“They both lodged in your house?”

“I have no reason to deny it.”

“But neither she herself, nor Monsieur de Lamotte, had at first intended that she should accept a lodging in the house which you occupied.”

“That is quite true.  We had important accounts to settle, and Madame de Lamotte told me afterwards that she feared some dispute on the question of money might arise between us—­at least, that is the reason she gave me.  She was mistaken, as the event proved, since I always intended to pay, and I have paid.  But she may have had another reason which she preferred not to give.”

“It was the distrust of this man which she felt,” exclaimed Monsieur de Lamotte.  Derues answered only with a melancholy smile.

“Silence, monsieur,” said the magistrate, “silence; do not interrupt.”  Then addressing Derues—­

“Another motive?  What motive do you suppose?”

“Possibly she preferred to be more free, and able to receive any visitor she wished.”

“What do you mean?”

“It is only supposition on my part, I do not insist upon it.”

“But the supposition appears to contain a hint injurious to Madame de Lamotte’s reputation?”

“No, oh no!” replied Derues, after a moment’s silence.

This sort of insinuation appeared strange to the magistrate, who resolved to try and force Derues to abandon these treacherous reticences behind which he sheltered himself.  Again recommending silence to Monsieur de Lamotte, he continued to question Derues, not perceiving that he was only following the lead skilfully given by the latter, who drew him gradually on by withdrawing himself, and that all the time thus gained was an advantage to the accused.
