 Why is the Brain so effective?
So when the Chief of World Security told him that he had been selected as the answer to the Solar System's greatest mystery, Jery assumed that it was because of his mental agility. I couldn't find anything really incriminating, unless maybe it was that hair dye that unexpectedly turned bright green after six weeks in the hair, but that was the lab's fault, not mine. Security men were not hired for their loquaciousness. But if I spot it in less, they throw it out and start over again. "You were chosen, from all the inhabitants of this planet, and all the inhabitants of the Earth Colonies, by the Brain." Chief of Security or not, I was getting a little burned up at his highhanded treatment of my emotions.
