He stared at Torry, and the expression on his face changed as he saw the blaster. He started a movement toward his own clipped weapon.

"Don't try it, Bart," ordered Torry sharply. "I think I'd enjoy killing you."

Bart Roper sighed deeply. "You took unfair advantage of me," he complained. "I thought you were hurt or killed. I was coming to see—"

"To make sure of me, if you'd missed? Maybe not. Maybe you did have a human impulse for once. I'll try to think so. And you can see how much it hurts when someone takes advantage of any human weakness. It hurts, doesn't it?"

Roper nodded slowly. "It does. So you've got me! Don't be so proud of yourself. It wasn't that hard. I was cooked from the moment your police pals got their hands on the transmitter. It was my only way out. You know that, of course. I just wanted the pleasure of taking some of you with me. I'm not going back to Mars. The disintegrators, or life in the prison mines don't appeal to me. So you'd better kill me now."

"I will if you force me," Torry told him wearily. "But I'm not making it that easy for you. There's a choice, but you won't like it. I've made a deal with Grannar. You can die now, or you can go back to Earth to the clinic."

"The clinic!" shrieked Roper. "You know what that means. I wouldn't be the same person. Maybe not even human."

Torry steadied his eyes on his brother. "I'm not sure you ever were human. But you need treatment. They'll knock out your thymus, drug you and shock you and carve you till you'll never know yourself. You won't be an antisocial monster with the emotional stasis of a child. You won't be anything you've ever been. But you may be a man. And you'll stop hurting people, or they'll stop you for good. The choice is yours—right now. So make up both our minds before I decide to shoot."

Roper yielded with a grimace of distaste. "You win, Torry. You always did, sooner or later. I was quicker, but you were smarter. I guess Rose was the last of your toys I'll ever swipe. And it's back to kindergarten for Bart Roper."

Torry relaxed, though he still did not lower his gun.
