“What passed between you and that diabolical-looking man in those few minutes?” she asked at length.

“I have sold my soul to him.  I feel it; I am no longer the same.  He has taken my self, and given me his soul in exchange.”

“What?”

“You would not understand it at all....  Ah! he was right,” Castanier went on, “the fiend was right!  I see everything and know all things.—­You have been deceiving me!”

Aquilina turned cold with terror.  Castanier lighted a candle and went into the dressing room.  The unhappy girl followed him in dazed bewilderment, and great was her astonishment when Castanier drew the dresses that hung there aside and disclosed the sergeant.

“Come out, my boy,” said the cashier; and, taking Leon by a button of his overcoat, he drew the officer into his room.

The Piedmontese, haggard and desperate, had flung herself into her easy chair.  Castanier seated himself on a sofa by the fire, and left Aquilina’s lover in a standing position.

“You have been in the army,” said Leon; “I am ready to give you satisfaction.”

“You are a fool,” said Castanier dryly.  “I have no occasion to fight.  I could kill you by a look if I had any mind to do it.  I will tell you what it is, youngster; why should I kill you?  I can see a red line round your neck—­the guillotine is waiting for you.  Yes, you will end in the Place de Greve.  You are the headsman’s property! there is no escape for you.  You belong to a vendita of the Carbonari.  You are plotting against the Government.”

“You did not tell me that,” cried the Piedmontese, turning to Leon.

“So you do not know that the Minister decided this morning to put down your Society?” the cashier continued.  “The Procureur-General has a list of your names.  You have been betrayed.  They are busy drawing up the indictment at this moment.”

“Then was it you who betrayed him?” cried Aquilina, and with a hoarse sound in her throat like the growl of a tigress she rose to her feet; she seemed as if she would tear Castanier in pieces.

“You know me too well to believe it,” Castanier retorted.  Aquilina was benumbed by his coolness.

“Then how did you know it?” she murmured.

“I did not know it until I went into the drawing-room; now I know it—­now I see and know all things, and can do all things.”

The sergeant was overcome with amazement.

“Very well then, save him, save him, dear!” cried the girl, flinging herself at Castanier’s feet.  “If nothing is impossible to you, save him!  I will love you, I will adore you, I will be your slave and not your mistress.  I will obey your wildest whims; you shall do as you will with me.  Yes, yes, I will give you more than love; you shall have a daughter’s devotion as well as ...  Rodolphe! why will you not understand!  After all, however violent my passions may be, I shall be yours forever!  What should I say to persuade you?  I will invent pleasures ...  I ...  Great heavens! one moment! whatever you shall ask of me—­to fling myself from the window, for instance—­you will need to say but one word, ‘Leon!’ and I will plunge down into hell.  I would bear any torture, any pain of body or soul, anything you might inflict upon me!”
