Silence hung tensely between the control room of the ship and Colonel Halter's office on Earth. The captain was glaring now at Halter. A tear showed in the corner of each of Dr. Anna Mueller's old eyes. Lieutenant Brady was gripping the arms of his chair. Daniel Carlyle's eyes were closed and his head shook slightly, as though from palsy. There was a faint, enigmatic smile on Caroline Gordon's face. The cords on Crowley's neck stood out through the tan and wrinkled wrapping-paper skin.

By God, thought Halter, they're all sane except the captain. And they've got to do it. They've got to come out on their own steam or die in that control room.

"I'm waiting," he said. "Is your work going to die and you with it?"

"We'll leave all the records," said the captain, his thumb poised over the button on the arm of his chair. "That's enough."

Halter ignored him. "Each of you can help. You've only done part of the work." He stood and struck the desk with the flat of his hand. "Damn it, say something, one of you!"

Still the silence and the flickering looks all around.

Halter heard a sob. He saw Dr. Anna Mueller's head drop forward and her shoulders tremble. The others were staring at her, as if she had suddenly materialized among them, like a ghost.

Then her voice, through the trembling and the faint crying: "I've—I've got to know."

The captain got creakily to his feet. "Dr. Mueller! Do you want me to use the gun again?"
