combat engineering. It is called 'Command Isolation Geometry.' There are certain theorems which, if applied, will tell you the probable location of the command post of an enemy army corps or a city. When you have worked it out, you can then slip in, plant the bombs and– bango-the enemy has no central command post and can be more easily overrun by the Fleet or its marines or even the Army."
"You mean we're going to blow something up?" said the Countess Krak.
"No, no. I was just telling you what the mathematics was," Heller whispered back. "I've got this spore project to clean up the atmosphere. I'm just making sure I isolate whoever's toes it will step on so I won't be too surprised. The way this planet is organized, apparently, is that if you try to do anything to help it, some special-interest group jumps all over you. They have some crazy idea that chaos is profit. Very short-range think. So I am just making sure that when I start putting spores into the
stratosphere and get shot at, I know who's shooting."
"You mean somebody might object to cleaning up the atmosphere?" whispered Krak in surprise.
"You never know," said Heller.
"What a crazy planet!" she muttered.
"Well, be that as it may," he whispered, "but I'm getting some crazy answers here. I don't quite understand it."
"Let me help. I may not know your geometry but I'm good at puzzles."
He oriented the sheet so she could see it better. "I'm getting a repeating answer," he whispered. "When you get one of those, it means that your original premise is too narrow. I started out to find out who had connections and communication lines to the subject of cytology- which is an Earth name for our cellology. So I made a test equation over here in the corner of the sheet and, yes, I assumed too narrow a subject to get a reliable answer. Whatever the answer is, it controls and commands more than cytology. Do you follow me?"
"No."
"Well, it's like I started out to find a corporal in charge of a squad and then found out that wouldn't embrace the area, so I found a captain in charge of a company and that wouldn't embrace the target area, so then I found a colonel in charge of a regiment. This could take forever. I'm nowhere near any real top authority command post."
"How are you doing it?"
"Well, this symbol here is logistic lines like vehicles and supply trucks. And you see its path of emanation and convergence. And this is a symbol of communications. And so on. So if you can get such functions to cross on the plot, you have the command post area."
"It looks very pretty and orderly," whispered the
Countess. "And, looking at the lines, it does seem you have convergences."
"Too many," said Heller. "And they always go off to somewhere else. Blast it." He gave her the sheet. He was really throwing it away, as he now took a big fresh one. "I was doing it for a country. I'm just going to skip a continent and be absurd. I'll do it for the whole planet."
"Why is that absurd, Jettero? I never saw you do anything absurd in all the time I've known you." But she added in a lower mutter, "Except Miss Simmons, of course."
"It's absurd because this planet doesn't have an emperor. I'll wind up with Buckingham Palace in England or something."
"And then you'll blow that up and we can leave," said the Countess Krak with an air of finality.
He laughed quietly. "What a bloodthirsty wench. I'm not trying to find out who to shoot. I'm just trying to find out who might shoot at me if I put spores in the stratosphere." He was checking book titles in the towers around him. "Let's see if I have all the planetary control subjects." He began to put them down. Government control. Fuel control. Finance control. Health control. Intelligence control. Medical control. Medicine control. Mental services control. Media control. Law enforcement control. Judicial control. Food control. Air transport control. Industrial control. Social control. Population volume control.... He was checking
