"Yes, sir," Malone said. He paused. "What problem, sir?" he added.

"The problem we're discussing," Burris said. He gave Malone a bright, blank stare. "Just listen to me."

"Yes, sir."

"All right, then." Burris took a deep breath. He seemed nervous. Once again he stood up and went to the window. This time, he spoke without turning. "Remember how everybody used to laugh about spaceships, and orbital satellites, and life on other planets? That was just in those 'Lucky Starr' books. That was all just for kids, wasn't it?"

"Well, I don't know," Malone said slowly.

"Sure it was all for kids," Burris said. "It was laughable. Nobody took it seriously."

"Well, somebody must—"

"You just keep quiet and listen," Burris said.

"Yes, sir," Malone said.

Burris nodded. His hands were clasped behind his back. "We're not laughing any more, are we, Malone?" he said without moving.
