Such a state of warfare could not continue any longer.
Thérèse and Laurent had both reached the point of pondering on the advisability of extricating themselves from the consequences of their first crime, by committing a second. It became absolutely necessary that one of them should disappear so that the other might enjoy some repose. This reflection came to them both at the same time; both felt the urgent necessity for a separation, and both desired that it should be eternal. The murder that now occurred to their minds, seemed to them natural, fatal and forcibly brought about by the murder of Camille. They did not even turn the matter over in their heads but welcomed the idea as the only means of safety. Laurent determined he would kill Thérèse because she stood in his way, because she might ruin him by a word, and because she caused him unbearable suffering. Thérèse made up her mind that she would kill Laurent, for the same reasons.
The firm resolution to commit another murder somewhat calmed them. They formed their plans. But in that respect they acted with feverish excitement, and without any display of excessive prudence. They only thought vaguely of the probable consequences of a murder committed without flight and immunity being ensured. They felt the invincible necessity to kill one another, and yielded to this necessity like furious brutes. They would not have exposed themselves for their first crime, which they had so cleverly concealed, and yet they risked the guillotine, in committing a second, which they did not even attempt to hide.
Here was a contradiction in their conduct that they never so much as caught sight of. Both simply said to themselves that if they succeeded in fleeing, they would go and live abroad, taking all the cash with them. Thérèse, a fortnight or three weeks before, had drawn from the bank the few thousand francs that remained of her marriage portion, and kept them locked up in a drawer—a circumstance that had not escaped Laurent. The fate of Madame Raquin did not trouble them an instant.
A few weeks previously, Laurent had met one of his old college friends, now acting as dispenser to a famous chemist, who gave considerable attention to toxicology. This friend had shown him over the laboratory where he worked, pointing out to him the apparatus and the drugs.
One night, after he had made up his mind in regard to the murder, and as Thérèse was drinking a glass of sugar and water before him, Laurent remembered that he had seen in this laboratory a small stoneware flagon, containing prussic acid, and that the young dispenser had spoken to him of the terrible effects of this poison, which strikes the victim down with sudden death, leaving but few traces behind. And Laurent said to himself, that this was the poison he required. On the morrow, succeeding in escaping the vigilance of Thérèse, he paid his friend a visit, and while he had his back turned, stole the small stoneware flagon.
The same day, Thérèse took advantage of the absence of Laurent, to send the large kitchen knife, with which they were in the habit of breaking the loaf sugar, and which was very much notched, to be sharpened. When it came back, she hid it in a corner of the sideboard.
CHAPTER XXXII
The following Thursday, the evening party at the Raquins, as the guests continued to term the household of their hosts, was particularly merry. It was prolonged until half-past eleven, and as Grivet withdrew, he declared that he had never passed such a pleasant time.
Suzanne, who was not very well, never ceased talking to Thérèse of her pain and joy. Thérèse appeared to listen to her with great interest, her eyes fixed, her lips pinched, her head, at moments, bending forward; while her lowering eyelids cast a cloud over the whole of her face.
