Under this avalanche of meanings, Idaho again shook his head from side to side.

“In the wrong hands,” Leto said, “monolithic centralized power is a dangerous and volatile instrument.”

“And your hands are the right ones?”

“I’m not certain about my hands, but I will tell you, Duncan, I’m certain about the hands of those who’ve gone before me. I know them.”

Idaho turned his back on Leto.

What a fascinating, ultimately human gesture, Leto thought. Rejection coupled to acceptance of his vulnerability.

Leto spoke to Idaho’s back.

“You object quite rightly that I use people without their full knowledge and consent.”

Idaho turned his profile to Leto, then turned his head to look up at the cowled face, cocking his head forward a bit to peer into the all-blue eyes.

He is studying me, Leto thought, but he has only the face to measure me by.

The Atreides had taught their people to know the subtle signals of face and body, and Idaho was good at it, but the realization could be seen coming over him: he was over his depth here.

Idaho cleared his throat. “What’s the worst thing you would ask of me?”

How like a Duncan! Leto thought. This one was a classic. Idaho would give his loyalty to an Atreides, to the guardian of his oath, but he sent a signal that he would not go beyond the personal limits of his own morality.

“You will be asked to guard me by whatever means necessary, and you will be asked to guard my secret.”

“What secret?”

“That I am vulnerable.”

“That you’re not God?”

“Not in that ultimate sense.”

“Your Fish Speakers talk about rebels.”

“They exist.”

“Why?”

“They are young and I have not convinced them that my way is better. It’s very difficult convincing the young of anything. They’re born knowing so much.”

“I never before heard an Atreides sneer at the young that way.”

“Perhaps it’s because I’m so much older—old compounded by old. And my task gets more difficult with each passing generation.”

“What is your task?”

“You will come to understand it as we go along.”

“What happens if I fail you? Do your women eliminate me?”

“I try not to burden the Fish Speakers with guilt.”

“But you would burden me?”

“If you accept it.”

“If I find that you’re worse than the Harkonnens I’ll turn against you.”

How like a Duncan. They measure all evil against the Harkonnens. How little they know of evil.

Leto said: “The Baron ate whole planets, Duncan. What could be worse than that?”

“Eating the Empire.”

“I am pregnant with my Empire. I’ll die giving birth to it.”

“If I could believe that…”

“Will you command my Guard?”

“Why me?”

“You’re the best.”

“Dangerous work, I’d imagine. Is that how my predecessors died, doing your dangerous work?”

“Some of them.”

“I wish I had the memories of those others!”

“You couldn’t have and still be the original.”

“I want to learn about them, though.”
