Then she settled herself beside La Grivotte, made her rest her head against her shoulder, and wiped the blood from her lips. The attack subsided, but weakness was coming back, so extreme that the wretched woman was scarcely able to stammer: "Oh, it is nothing, nothing at all; I am cured, I am cured, completely cured!"

Pierre was thoroughly upset: This sudden, overwhelming relapse had sent an icy chill through the whole carriage. Many of the passengers raised themselves up and looked at La Grivotte with terror in their eyes. Then they dived down into their corners again, and nobody spoke, nobody stirred any further. Pierre, for his part, reflected on the curious medical aspect of this girl's case. Her strength had come back to her over yonder. She had displayed a ravenous appetite, she had walked long distances with a dancing gait, her face quite radiant the while; and now she had spat blood, her cough had broken out afresh, she again had the heavy ashen face of one in the last agony. Her ailment had returned to her with brutal force, victorious over everything. Was this, then, some special case of phthisis complicated by neurosis? Or was it some other malady, some unknown disease, quietly continuing its work in the midst of contradictory diagnosis? The sea of error and ignorance, the darkness amidst which human science is still struggling, again appeared to Pierre. And he once more saw Doctor Chassaigne shrugging his shoulders with disdain, whilst Doctor Bonamy, full of serenity, quietly continued his verification work, absolutely convinced that nobody would be able to prove to him the impossibility of his miracles any more than he himself could have proved their possibility.

"Oh! I am not frightened," La Grivotte continued, stammering. "I am cured, completely cured; they all told me so, over yonder."

Meantime the carriage was rolling, rolling along, through the black night. Each of its occupants was making preparations, stretching himself out in order to sleep more comfortably. They compelled Madame Vincent to lie down on the seat, and gave her a pillow on which to rest her poor pain-racked head; and then, as docile as a child, quite stupefied, she fell asleep in a nightmare-like torpor, with big, silent tears still flowing from her closed eyes. Elise Rouquet, who had a whole seat to herself, was also getting ready to lie down, but first of all she made quite an elaborate toilet, tying the black wrap which had served to hide her sore about her head, and then again peering into her glass to see if this headgear became her, now that the swelling of her lip had subsided. And again did Pierre feel astonished at sight of that sore, which was certainly healing, if not already healed—that face, so lately a monster's face, which one could now look at without feeling horrified. The sea of incertitude stretched before him once more. Was it even a real lupus? Might it not rather be some unknown form of ulcer of hysterical origin? Or ought one to admit that certain forms of lupus, as yet but imperfectly studied and arising from faulty nutrition of the skin, might be benefited by a great moral shock? At all events there here seemed to be a miracle, unless, indeed, the sore should reappear again in three weeks', three months', or three years' time, like La Grivotte's phthisis.

It was ten o'clock, and the people in the carriage were falling asleep when they left Lamothe. Sister Hyacinthe, upon whose knees La Grivotte was now drowsily resting her head, was unable to rise, and, for form's sake, merely said, "Silence, silence, my children!" in a low voice, which died away amidst the growling rumble of the wheels.

However, something continued stirring in an adjoining compartment; she heard a noise which irritated her nerves, and the cause of which she at last fancied she could understand.

"Why do you keep on kicking the seat, Sophie?" she asked. "You must get to sleep, my child."

"I'm not kicking, Sister. It's a key that was rolling about under my foot."

"A key!—how is that? Pass it to me."

Then she examined it. A very old, poor-looking key it was—blackened, worn away, and polished by long use, its ring bearing the mark of where it had been broken and resoldered. However, they all searched their pockets, and none of them, it seemed, had lost a key.
