With all its voices, with the voice of friendship as well as that of public opinion, society called to her to rise and resume possession of herself. That was her duty, according to the world, a term which in such case is equivalent to general order, the interest of society: "Follow the straight road; let those perish who wander from it."--And religion added: "The virtuous and the good for everlasting salvation, the blind and the rebellious for hell!"--Does it matter little to the wise man, pray, that the fool perishes? Thérèse was shocked at that conclusion. "On the day that I deem myself the most perfect, the most useful and the best creature on earth," she said to herself, "I will consent to a sentence of death against all others; but if that day does not come, shall I not be more mad than all the other madmen? Back, madness of vanity, the mother of selfishness! Let us continue to suffer for others than ourselves!" It was almost midnight when she rose from the chair upon which she had sunk, crushed and spiritless, four hours before. Someone rang. A messenger brought a box and a note. The box contained a domino and a black satin mask. The note contained these words in Laurent's handwriting: _Senza veder, senza parlar_. Without seeing or speaking to each other!--What was the key to that enigma? Did it mean that she should go to the masked ball to amuse him by a commonplace intrigue? Did he mean to try to fall in love with her without knowing her? Was it the fancy of a poet, or the insult of a libertine? Thérèse sent away the box, and fell back in her chair; but a feeling of uneasiness made it impossible for her to reflect. Ought she not to try every expedient to rescue that victim from his infernal aberrations? "I will go," she said, "I will follow him step by step. I will see, I will listen to his life away from me, I will learn how much truth there is in the villainous stories he tells me, whether he loves evil innocently or with affectation, whether he really has depraved tastes or is only seeking to distract his thoughts. Knowing all that I have hitherto tried not to know of him and his vile associates, all that I have striven with disgust to keep from his memory and my imagination, perhaps I shall discover some weak spot, some pretext for curing him of this vertigo." She remembered the domino Laurent had sent her, although she had barely glanced at it. It was of satin. She sent for one of Naples silk, donned a mask, carefully covered her hair, supplied herself plentifully with bows of ribbon, in order to change her appearance more completely in case Laurent should suspect her identity, and, sending for a carriage, she set out, alone and resolutely, for the Opera ball.
