At this, Guillaume, who had kept Pierre’s hand in his own, pressed it more tightly, and in a trembling voice exclaimed: “Yes, yes, and that will be good and brave too. Go there, brother, go there.”

That house of the Rue des Saules, that horrible home of want and agony, had lingered in Pierre’s memory. To him it was like an embodiment of the whole filthy cloaca, in which the poor of Paris suffer unto death. And on returning thither that afternoon, he found the same slimy mud around it; its yard littered with the same filth, its dark, damp stairways redolent of the same stench of neglect and poverty, as before. In winter time, while the fine central districts of Paris are dried and cleansed, the far-away districts of the poor remain gloomy and miry, beneath the everlasting tramp of the wretched ones who dwell in them.

Remembering the staircase which conducted to Salvat’s lodging, Pierre began to climb it amidst a loud screaming of little children, who suddenly became quiet, letting the house sink into death-like silence once more. Then the thought of Laveuve, who had perished up there like a stray dog, came back to Pierre. And he shuddered when, on the top landing, he knocked at Salvat’s door, and profound silence alone answered him. Not a breath was to be heard.

However, he knocked again, and as nothing stirred he began to think that nobody could be there. Perhaps Salvat had returned to fetch the woman and the child, and perhaps they had followed him to some humble nook abroad. Still this would have astonished him; for the poor seldom quit their homes, but die where they have suffered. So he gave another gentle knock.

And at last a faint sound, the light tread of little feet, was heard amidst the silence. Then a weak, childish voice ventured to inquire: “Who is there?”

“Monsieur l’Abbé.”

The silence fell again, nothing more stirred. There was evidently hesitation on the other side.

“Monsieur l’Abbé who came the other day,” said Pierre again.

This evidently put an end to all uncertainty, for the door was set ajar and little Céline admitted the priest. “I beg your pardon, Monsieur l’Abbé,” said she, “but Mamma Théodore has gone out, and she told me not to open the door to anyone.”

Pierre had, for a moment, imagined that Salvat himself was hiding there. But with a glance he took in the whole of the small bare room, where man, woman and child dwelt together. At the same time, Madame Théodore doubtless feared a visit from the police. Had she seen Salvat since the crime? Did she know where he was hiding? Had he come back there to embrace and tranquillise them both?
