Drake frowned. His eyes withdrew beneath a lowered brow and Rose felt some of her resolution begin to leave her. He said, "I thought it was agreed that you would not question me about my business in this matter."
"I think it's too late for that. I know too much about your business by now."
"What do you mean?" he shouted, jumping to his feet. Recollecting himself, he approached, laid his hands upon her shoulders and repeated in a lower voice, "What do you mean?"
Rose kept her eyes upon her hands, which rested limply in her lap. She bore the painfully gripping fingers patiently, and said slowly, "Dr. Tholan thinks that Earth is spreading the Inhibition Death purposely. That's it, isn't it?"
She waited. Slowly, the grip relaxed and he was standing there, hands at his side, face baffled and unhappy. He said, "Where did you get that notion?"
"It's true, isn't it?"
He said breathlessly, unnaturally, "I want to know exactly why you say that. Don't play foolish games with me, Rose. This is for keeps."
"If I tell you, will you answer one question? Is Earth spreading the disease deliberately, Drake?"
Drake flung his hands upward. "Oh, for Heaven's sake!"
He knelt before her. He took her hands in his and she could feel their trembling. He was forcing his voice into soothing, loving syllables.
He was saying, "Rose dear, look, you've got something red-hot by the tail and you think you can use it to tease me in a little husband-wife repartee. No, I'm not asking much. Just tell me exactly what causes you to say what - what you have just said." He was terribly earnest about it.
"I was at the New York Academy of Medicine this afternoon. I did some reading there."
"But why? What made you do it?"
"You seemed so interested in the Inhibition Death, for one thing. And Dr. Tholan made those statements about the incidence increasing since interstellar travel, and being the highest on the planet nearest Earth." She paused.
"And your reading?" he prompted. "What about your reading, Rose?" c She said, "It backs him up. All I could do was to skim hastily into the direction of their research in recent decades. It seems obvious to me, though, that at least some of the Hawkinsites are considering the possibility the Inhibition Death originates on Earth."
"Do they say so outright?"
"No. Or, if they have, I haven't seen it." She gazed at him in surprise. In a matter like this, certainly the government would have investigated Hawkinsite research on the matter. She said, gently, "Don't you know about Hawkinsite research in the matter, Drake? The government - "
"Never mind about that." Drake had moved away from her and now he turned again. His eyes were bright. He said, as though making a wonderful discovery, "Why, you're an expert in this!"
Was she? Did he find that out only now that he needed her? Her nostrils flared and she said flatly, "I am a biologist."
He said, "Yes, I know that, but I mean your particular specialty is growth. Didn't you once tell me you had done work on growth?"
"You might call it that. I've had twenty papers published on the relationship of nucleic acid fine structure and embryonic development on my Cancer Society grant."
"Good. I should have thought of that." He was choked with a new excitement. "Tell me, Rose - Look, I'm sorry if I lost my temper with you a moment ago. You'd be as competent as anyone to understand the direction of their researches if you read about it, wouldn't you?"
"Fairly competent, yes."
"Then tell me how they think the disease is spread. The details, I mean."
"Oh, now look, that's asking a little too much. I spent a few hours in the Academy, that's all. I'd need much more time than that to be able to answer your question."
"An intelligent guess, at least. You can't imagine how important it is."
She said, doubtfully, "Of course, 'Studies on Inhibition' is a major treatise in the field. It would summarize all of the available research data."
"Yes? And how recent is it?"
"It's one of those periodic things. The last volume is about a year old."
"Does it have any account of his work in it?" His finger jabbed in the direction of Harg Tholan's bedroom.
"More than anyone else's. He's an outstanding worker in the field. I looked over his papers especially."
"And what are his theories about the origin of the disease? Try to remember, Rose."
She shook her head at him. "I could swear he blames Earth, but he admits they know nothing about how the disease is spread. I could swear to that, too."
He stood stiffly before her. His strong hands were clenched into fists at his side and his words were scarcely more than a mutter. "It could be a matter of complete overestimation. Who knows - "
He whirled away. "I'll find out about this right now, Rose. Thank you for your help."
She ran after him. "What are you going to do?"
"Ask him a few questions." He was rummaging through the drawers of his desk and now his right hand withdrew. It held a needle-gun.
She cried, "No, Drake!"
He shook her off roughly, and turned down the corridor toward the Hawkinsite's bedroom.
Drake threw the door open and entered. Rose was at his heels, still trying to grasp his arm, but now he stopped and looked at Harg Tholan.
The Hawkinsite was standing there motionless, eyes unfocused, his four standing limbs sprawled out in four directions as far as they would go. Rose felt ashamed of intruding, as though she were violating an intimate rite. But Drake, apparently unconcerned, walked to within four feet of the creature and stood there. They were face to face, Drake holding the needle-gun easily at a level of about the center of the Hawkinsite's torso.
