Then she knew that the light had gone out; and suddenly she felt her teeth chatter, and a chill ran through her bones that was bad to feel. She raised her head and saw that the great walls were dark against the starry sky, and she rose with an effort, as if her limbs had suddenly become lead. But she could walk, though it was like walking in sleep.
She did not afterwards remember how she got home, but she had a vague recollection of having lost her way, and of finding a cab at last, and then of letting herself into the little apartment in the dark.
When she was next aware of anything it was broad daylight, and she was lying on her bed, still dressed and wearing her cloak; and Kalmon was bending over her, his eyes on hers and his fingers on her pulse, while old Teresa watched her anxiously from the foot of the bed.
"I'm afraid it is a 'perniciosa,'" he said. "Put her to bed while I call a regular doctor."
Regina looked up at him.
"I have fever, have I not?" she asked quite quietly.
"Yes. You have a little fever," he answered, but his big brown eyes were very grave.
When Marcello came, an hour later, she did not know him. She stared at him with wide, unwinking eyes, and there were bright patches of colour in her cheeks. Already there were hollows in them, too, and at her temples, for the perniciosa fever is frightfully quick to waste the body. In the Campagna, where it is worst, men have died of it in less than four hours after first feeling it upon them. Great men have discovered wonderful remedies for it, but still it kills.
Kalmon got one of the great men, who was his friend, and they did what they could. A nursing sister came and was installed. Marcello was summoned away soon after noon by an official person, who brought a carriage and said that Corbario was now conscious and able to speak, and that it was absolutely necessary that Marcello should be confronted with him, as he might not live another day. It was easier to go than it would have been if Regina had been conscious, but even so it was very hard. The nun and Teresa stayed with her.
