When he finished, Professor Maddox was enthusiastic. "I believe he's on the right track," he said. "Unfortunately, he hasn't told all he knows in this report. He must have been too excited about the work. Ordinarily, he leaves nothing out, but he's omitted three or four important steps near the end. I'll have to ask him to fill them in before we can do very much with his processes."
The report was read and discussed at the college laboratory the next day, and the scientists began preliminary work to duplicate Dr. French's results. Ken and his father hurried home early in order to meet the afternoon schedule with Berkeley and get Dr. French to the microphone to answer the questions he had neglected to consider.
As they arrived at the radio shack and opened the door they found Maria inside, with her head upon the desk. Deep sobs shook her body. The receiver was on, but only the crackle of static came from it. The filaments of the transmitter tubes were lit, but the antenna switch was open. The tape recorder was still running.
Professor Maddox grasped Maria by the shoulders and drew her back in the chair. "What is the matter?" he exclaimed. "Why are you crying, Maria?"
"It's all over," she said. "There's nothing more down there. Just nothing..."
"What do you mean?" Ken cried.
"It's on the tape. You can hear it for yourself."
Ken quickly reversed the tape and turned it to play. In a moment the familiar voice of their Berkeley friend was heard. "I'm glad you're early," it said. "There isn't much time today. The thing Dr. French feared has happened.
"Half the Bay Area is in flames. On the campus here, the administration building is gone. They tried to blow up the science building. It's burning pretty fast in the other wing. I'm on the third floor. Did I ever tell you I moved my stuff over here to be close to the lab?
"There must be a mob of a hundred thousand out there in the streets. Or rather, several hundred mobs that add up to that many. None of them know where they're going. It's like a monster with a thousand separate heads cut loose to thrash about before it dies. I see groups of fifty or a hundred running through the streets burning and smashing things. Sometimes they meet another group coming from the opposite direction. Then they fight until the majority of one group is dead, and the others have run away.
