"Anything you please," said the woman, still frightened. Bernardet smiled.

"Come! come! What do you want for it? Fifty francs, eh? Fifty?"

"Away with your fifty francs! I place it at your disposal for nothing, if you need it."

Bernardet paid the sum he had named. He had always exactly, as if by principle, a fifty-franc note in his pocketbook. Very little money; a few white pieces, but always this note in reserve. One could never tell what might hinder him in his researches. He paid, then, this note, adding that in all probability Mme. Colard would soon be cited before the Examining Magistrate to tell him about this Charles Breton.

"I cannot say anything else, for I do not know anything else," said the huge widow, whose breast heaved with emotion.

She wrapped up the picture in a piece of silk paper, then in a piece of newspaper, which chanced to be the very one in which Paul Rodier had published his famous article on "The Crime of the Boulevard de Clichy." Bernardet left enchanted with his "find," and repeated over and over to himself: "It is very precious! It is a tid-bit!"

Should he keep on toward the Préfecture to show this "find" to his Chief, or should he go at once to hunt up Charles Breton at the address he had given?

Bernardet hesitated a moment, then he said to himself that, in a case like this, moments were precious; an hour lost was time wasted, and that as the address which Breton had given was not far away, he would go there first. "Rue de la Condamine, 16," that was only a short walk to such a tramper as he was. He had good feet, a sharp eye and sturdy legs; he would soon be at the Batignolles. He had taken some famous tramps in his time, notably one night when he had scoured Paris in pursuit of a malefactor. This, he admitted, had wearied him a little; but this walk from the Avenue des Bons-Enfants to the Rue de la Condamine was but a spurt. Would he find that a false name and a false address had been given? This was but the infancy of art. If, however, he found that this Charles Breton really did live at that address and that he had given his true name, it would probably be a very simple matter to obtain all the information he desired of Jacques Dantin.

"What do I risk? A short walk," thought Bernardet, "a little fatigue—that can be charged up to Profit and Loss."

He hurried toward the street and number given. It was a large house, several stories high. The concierge was sweeping the stairs, having left a card bearing this inscription tacked on the front door. "The porter is on the staircase." Bernardet hastened up the stairs, found the man and questioned him. There was no Charles Breton in the house; there never had been. The man who sold the portrait had given a false name and address. Vainly did the police officer describe the individual who had visited Mme. Colard's shop. The man insisted that he had never seen any one who in the least resembled this toreador in the big felt hat. It was useless to insist! Mme. Colard had been deceived. And now, how to find, in this immense city of Paris, this bird of passage, who had chanced to enter the bric-a-brac shop. The old adage of "the needle in the haystack" came to Bernardet's mind and greatly irritated him. But, after all, there had been others whom he looked for; there had been others whom he had found, and probably he might still be able to find another trail. He had a collaborator who seldom failed him—Chance! It was destiny which often aided him.
