"A coincidence! An unparalleled coincidence, but one which now strikes me as a most powerful proof of innocence. I tell you that, if Marie Fauville had been clever enough to commit all those murders, she would also have been clever enough not to leave behind her a fruit bearing the marks of her two rows of teeth."
"But still—"
"She is innocent! And that is what I am going to tell the examining magistrate. She must be informed of the efforts that are being made in her favour. She must be given hope at once. If not, the poor thing will kill herself and her death will be on the conscience of all who accused an innocent woman. She must—"
At that moment he interrupted himself. His eyes were fixed on one of the journalists who was standing a little way off listening to him and taking notes.
He whispered to Mazeroux:
"Could you manage to find out that beggar's name? I can't remember where on earth I've seen him before."
But an usher now opened the door of the examining magistrate, who, on receiving Don Perenna's card, had asked to see him at once. He stepped forward and was about to enter the room with Mazeroux, when he suddenly turned to his companion with a cry of rage:
"It's he! It was Sauverand in disguise. Stop him! He's made off. Run, can't you?"
He himself darted away followed by Mazeroux and a number of warders and journalists, He soon outdistanced them, so that, three minutes later, he heard no one more behind him. He had rushed down the staircase of the "Mousetrap," and through the subway leading from one courtyard to the other. Here two people told him that they had met a man walking at a smart pace.
The track was a false one. He became aware of this, hunted about, lost a good deal of time, and managed to discover that Sauverand had left by the Boulevard du Palais and joined a very pretty, fair-haired woman—Florence Levasseur, obviously—on the Quai de l'Horloge. They had both got into the motor bus that runs from the Place Saint-Michel to the Gare Saint-Lazare.
