"Will you leave us alone, eh? Will you be good enough to look over there if we are at it?"
But Étienne, with white lips, shouted:
"If you don't let her go, I'll do for you!"
The other quickly stood up, for he had understood by the hiss of the voice that his mate was in earnest. Death seemed to them too slow; it was necessary that one of them should immediately yield his place. It was the old battle beginning over again, down in the earth where they would soon sleep side by side; and they had so little room that they could not swing their fists without grazing them.
"Look out!" growled Chaval. "This time I'll have you."
From that moment Étienne became mad. His eyes seemed drowned in red vapour, his chest was congested by the flow of blood. The need to kill seized him irresistibly, a physical need, like the irritation of mucus which causes a violent spasm of coughing. It rose and broke out beyond his will, beneath the pressure of the hereditary disease. He had seized a sheet of slate in the wall and he shook it and tore it out, a very large, heavy piece. Then with both hands and with tenfold strength he brought it down on Chaval's skull.
The latter had not time to jump backwards. He fell, his face crushed, his skull broken. The brains had bespattered the roof of the gallery, and a purple jet flowed from the wound, like the continuous jet of a spring. Immediately there was a pool, which reflected the smoky star of the lamp. Darkness was invading the walled-up cave, and this body, lying on the earth, looked like the black boss of a mass of rough coal.
Leaning over, with wide eyes, Étienne looked at him. It was done, then; he had killed. All his struggles came back to his memory confusedly, that useless fight against the poison which slept in his muscles, the slowly accumulated alcohol of his race. He was, however, only intoxicated by hunger; the remote intoxication of his parents had been enough. His hair stood up before the horror of this murder; and yet, in spite of the revolt which came from his education, a certain gladness made his heart beat, the animal joy of an appetite at length satisfied. He felt pride, too, the pride of the stronger man. The little soldier appeared before him, with his throat opened by a knife, killed by a child. Now he, too, had killed.
But Catherine, standing erect, uttered a loud cry:
"My God! he is dead!"
