Utdrag:
"I wish," he said drearily, looking at her, "that I could just forget it all. I don't see why anyone would come back for more of that."
She leaned forward to grip the edge of the mattress, shaking with laughter. She sat up again. "Whew!" she said, looking at him and forcing her face to be straight. "Nobody comes back for more. That is the unique quality of this drug. People come back to forget they ever had it."
He sat up. "I can forget that?"
"Oh, yes. Don't get so excited! That's what you really paid your thousand dollars for. The forgetfulness drug lingers in your bloodstream for two to three weeks. Then memory returns and you're due for another visit."
