"Here."

"Baden!"

"Here."

Through the open door, Joel could see a white uniformed guard sprawled on the floor. Blood trickled from his mouth and nose and the doctor was fussing over him.

The colonel reached the D's. Then he said, "Eriss."

There was no answer.

"Eriss!" he repeated. The silence was explosive. No one breathed.

Joel craned his neck, looked up and down the line. The shaggy ex-surgeon was conspicuously absent!

The colonel swore. He turned on an under-officer at his elbow. "That's the man!" he said savagely. "Get his dossier and put his picture on the televisor immediately!"

The under-officer sprinted from the room, almost collided with a man entering the prison. Joel saw that it was the guard who'd been lying unconscious outside the door. His white uniform was blood-spattered and he was holding a handkerchief to his nose.
