"I was only going to say that although I was no doubt to blame, I certainly had no idea that you could possibly consider the matter so important."

He seemed suddenly to rein himself in for a second or two, during which he glared at her fixedly. Then he burst out again with scathing venom, the more concentrated because he kept his voice low.

"You didn't consider it important! That's what you mean to say. Let me tell you that any nurse worth her salt does not rush off and leave her patient as you did just now in that cavalier fashion. It was your duty to ask my permission, to find out if I was ready for you to go. Your behaviour was undisciplined, un——"

"Oh, I see. Then it was my running off to help Mr. Clifford that was wrong, not losing the needle?"

She tried to keep sarcasm from her voice, realising that it was the first time in her career she had ever given anything approaching a "back answer," yet unable to resist making some retort. She saw an odd gleam come into the doctor's deepset eyes, an expression she did not understand. For the moment the cold scientist was non-existent.

"Find that needle," he commanded, his whole huge frame tense with suppressed fury. "It is the principle that matters. I have no use for careless people."

Then, as though maddened by the passivity of her regard, he lashed out at her once more, blindly cutting her with abuse that stung, even though it was entirely undeserved. A certain crude coarseness crept into his phrases, perhaps something long repressed had found vent. The cold, inert mass of him had turned into a volcano of vituperation.

Shaken and outraged, she felt that a few words more, and she would be compelled to say, "Very well, if that's what you think of me I'd better go at once and let you get another nurse." The sentence trembled on her lips, but she did not speak it. In her heart she knew why. The truth was she did not want to go. She was interested in her case; these people had been kind to her, and then—perhaps it was the real reason—there was Roger….

When at last the man paused for breath, she bowed her head slightly.

"I can only say again that I am sorry," she replied, and left the room.
