He paused rhetorically once more; then he added in the same tone: “Mental agitation and the terror of detection no doubt accelerated the fatal result in that instance. He died at once from the shock of the arrest. It was a natural conclusion. Here we may hope for a more successful issue.”
He spoke to the students, of course, but I could see for all that that he was keeping his falcon eye fixed hard on Hilda's face. I glanced aside at her. She never flinched for a second. Neither said anything directly to the other; still, by their eyes and mouths, I knew some strange passage of arms had taken place between them. Sebastian's tone was one of provocation, of defiance, I might almost say of challenge. Hilda's air I took rather for the air of calm and resolute, but assured, resistance. He expected her to answer; she said nothing. Instead of that, she went on holding the basin now with fingers that WOULD not tremble. Every muscle was strained. Every tendon was strung. I could see she held herself in with a will of iron.
The rest of the episode passed off quietly. Sebastian, having delivered his bolt, began to think less of Hilda and more of the patient. He went on with his demonstration. As for Hilda, she gradually relaxed her muscles, and, with a deep-drawn breath, resumed her natural attitude. The tension was over. They had had their little skirmish, whatever it might mean, and had it out; now, they called a truce over the patient's body.
When the case had been disposed of, and the students dismissed, I went straight into the laboratory to get a few surgical instruments I had chanced to leave there. For a minute or two, I mislaid my clinical thermometer, and began hunting for it behind a wooden partition in the corner of the room by the place for washing test-tubes. As I stooped down, turning over the various objects about the tap in my search, Sebastian's voice came to me. He had paused outside the door, and was speaking in his calm, clear tone, very low, to Hilda. “So NOW we understand one another, Nurse Wade,” he said, with a significant sneer. “I know whom I have to deal with!”
“And I know, too,” Hilda answered, in a voice of placid confidence.
“Yet you are not afraid?”
“It is not I who have cause for fear. The accused may tremble, not the prosecutor.”
“What! You threaten?”
“No; I do not threaten. Not in words, I mean. My presence here is in itself a threat, but I make no other. You know now, unfortunately, WHY I have come. That makes my task harder. But I will NOT give it up. I will wait and conquer.”
Sebastian answered nothing. He strode into the laboratory alone, tall, grim, unbending, and let himself sink into his easy chair, looking up with a singular and somewhat sinister smile at his bottles of microbes. After a minute he stirred the fire, and bent his head forward, brooding. He held it between his hands, with his elbows on his knees, and gazed moodily straight before him into the glowing caves of white-hot coal in the fireplace. That sinister smile still played lambent around the corners of his grizzled moustaches.
