"I'm Walker. But I'm not tops. Where'd you come from? With a Med Service uniform and a tormal on your shoulder you're not one of us! Have you come to argue that we ought to give in to Phaedra?"

Calhoun snorted.

"I've a message that an attack from space is due in three days, but that's all from Phaedra. I'm a Med Service man. How's the health situation? How are you equipped for doctors and such? How about hospitals? How's the death rate?"

The younger Walker grinned savagely.

"This is a new colony. I doubt there are a hundred people on the planet over twenty-five. How many doctors would there be in a population like ours? I don't think there is a death rate. Do you know how we came to be here?"

"Your father told me," said Calhoun, "at the military base on the next planet out. They're getting ready for an attack—and they asked me to warn you about it. Three days from now."

Young Walker ground his teeth.

"They won't dare attack. We'll smash them if they do. They lied to us! Worked us to death—"

"And no death rate?" asked Calhoun.

The younger man knitted his brows.
