About ten days after the conviction of Delessert, Pierre Nadaud called upon M. Huguet, the procureur-général of Strasbourg. He had a serious complaint to make of Delessert, _fils_. The young man, chiefly, he supposed, because he had given evidence against his father, appeared to be nourishing a monomaniacal hatred against him, Pierre Nadaud. 'Wherever I go,' said the irritated complainant, 'at whatever hour, early in the morning and late at night, he dogs my steps. I can in no manner escape him, and I verily believe those fierce, malevolent eyes of his are never closed. I really fear he is meditating some violent act. He should, I respectfully submit, be restrained--placed in a _maison de santé_, for his intellects are certainly unsettled; or otherwise prevented from accomplishing the mischief I am sure he contemplates.' M. Huguet listened attentively to this statement, reflected for a few moments, said inquiry should be made in the matter, and civilly dismissed the complainant. In the evening of the same day, Le Bossu was brought before M. Huguet. He replied to that gentleman's questioning by the avowal, that he believed Nadaud had murdered M. Destouches. 'I believe also,' added the young man, 'that I have at last hit upon a clue that will lead to his conviction.' 'Indeed! Perhaps you will impart it to me?' 'Willingly. The property in gold and precious gems carried off has not yet been traced. I have discovered its hiding-place.' 'Say you so? That is extremely fortunate.' 'You know, sir, that beyond the Rue des Vignes there are three houses standing alone, which were gutted by fire some time since, and are now only temporarily boarded up. That street is entirely out of Nadaud's way, and yet he passes and repasses there five or six times a day. When he did not know that I was watching him, he used to gaze curiously at those houses, as if to notice if they were being disturbed for any purpose. Lately, if he suspects I am at hand, he keeps his face determinedly _away_ from them, but still seems to have an unconquerable hankering after the spot. This very morning, there was a cry raised close to the ruins, that a child had been run over by a cart. Nadaud was passing: he knew I was close by, and violently checking himself, as I could see, kept his eyes fixedly _averted_ from the place, which I have no longer any doubt contains the stolen treasure.' 'You are a shrewd lad,' said M. Huguet, after a thoughtful pause. 'An examination shall at all events take place at nightfall. You, in the meantime, remain here under surveillance.'
