He took a deep breath. "We're in one hell of a jam, Liz; we've both been framed for something we haven't done. I know that Skardoth is responsible for the whole thing. He must be much older than he looks. How old would you say he was?"

Elizabeth shrugged. "Middle-aged, I'd say. Maybe nine hundred years."

Stern shook his head. "More than that. I've been keeping tabs on what has happened here on Earth for the past few centuries. By careful analysis, I've spotted the first time that Skardoth came to this planet." He reached out and touched her hand. "He's been here for more than twelve hundred years."

Her eyes narrowed. "That means that he's had some method of escape all these years. He's got an interstellar ship planted somewhere."

"Sure. He framed all of us; he's managed to get all of us sent here as criminals. Liz, I tell you, he's using us!"

She started to say something, but, at that moment, the car radio broke into life. A harsh voice said:

"Very pretty. I'm sorry to have to deal with both of you this way."

It was as though Skardoth's voice had galvanized him into action. Stern heard the voice, and, before it had finished, he had opened the door of the car and flung himself out.

He tried to push Elizabeth out the other way, but it was too late. Just as John Stern tumbled out of the car, a greenish-yellow cloud of radiance appeared in the front seat for a fraction of a second. When it faded, Elizabeth was gone.
