"Six hours?" Boyd stared. "That's going to take forever," he said.
"Well, he can set up a kind of assembly-line process and turn out a car every fifteen minutes. Any better?"
Boyd nodded.
"Good," Malone said. "There can't be so many 1972 red Cadillacs in the area that we can't get through them all at that speed." He thought a minute and then added: "By the way, you might check with the Cadillac dealers around town, and find out just how many there are, sold to people living in the area."
"And while I'm doing all that," Boyd said, "what are you going to be doing?"
Malone looked at him and sighed. "I'll worry about that," he said. "Just get started."
"Suppose Leibowitz can't find anything?" Boyd said.
"If Leibowitz can't find it, it's not there," Malone said. "He can find electronic devices anywhere in any car made, he says—even if they're printed circuits hidden under the paint job."
"Pretty good," Boyd said. "But suppose he doesn't?"
"Then they aren't there," Malone said, "and we'll have to think of something else." He considered that. It sounded fine. Only he wished he knew what else there was to think of.
