"Rat," she said presently, "I want to ask you something, rather personal? Your ... name. 'Rat'? Roberds told me something about your record. But ... please tell me, Rat. You didn't know the attack was coming, did you?"
He grinned again and waggled his head at her. "No. Who tell Rat?" Suddenly he was deadly serious as he spoke to her. "Rat a.w.o.l., go out to help sick man alone in desert. Rat leave post. Not time send call through. Come back with man, find horrible thing happen."
"But why didn't you explain?"
He grinned again. "Who believe? Sick man die soon after."
Gladney sat up. He had heard the conversation between the two. "You're right, Rat. No one would have believed you then, and no one will now. You've been safe enough on Mars, but the police will nab you as soon as you get out of the ship."
"They can't!" cried Patti Gray. "They can't hurt him after what he's done now."
The Centaurian grinned in a cynical way.
"Police not get me, Gladney. Gladney's memory damn punk, I think. Earth pretty nice place, maybe. But not for Rat."
Gladney stared at him for minutes. Then: "Say, I get it ... you're—"
"Shut up!" Rat cut him off sharply. "You talk too much." He cast a glance at Nurse Gray and then threw a meaning look at Gladney.
