"Can you be sure? Then don't sit there, man! Let's get on our way!"

Ellerbee shook his head. "He'll be dead before we can get there."

"How do you know he cracked up, anyway? Can you read that out of the crystal?"

Ellerbee nodded. "He kept it in his pocket. It's close enough to him to transmit the frantic messages of his dying mind."

"Then we've got to go! No matter if we get there in time or not."

Ellerbee shook his head again. "Sam is on his way over here. He's in touch with Baker. He says he thinks he can talk Baker back."

"Talk him back? What do you mean by that?"

Ellerbee hesitated. "I'm not sure. In some ways Sam understands a lot more about these things than I do. He can do things with the crystals that I don't understand. If he says he can talk Dr. Baker back, I think maybe he can."

"But we can't depend on that!" Fenwick said frantically. "Can't we get on our way in the car and let Sam do what he thinks he can while we drive? Maybe he can get Baker to hold on until we get him to a doctor."

"You don't understand," said Ellerbee. "Dr. Baker has gone over the edge. He's dying. I know what it's like. I looked into a dying mind once before. There is nothing whatever that a doctor can do after an organism starts dying. It's a definite process. Once started, it's irreversible."
