His remorse was purely physical. Only his body, strained nerves, and cowering flesh were afraid of the drowned man. Conscience played no part in his terrors, and he had not the slightest regret about killing Camille; in his moments of calm, when the spectre was not present, he would have committed the murder over again had he thought his interests required it.
Émile Zola, Thérèse Raquin
