There'd been no intimation of this metamorphosis when Leto had found Halleck with Ghadhean al-Fali in one of the small rebel sietches at Gare Ruden. With his blind companion, Leto had come up from the desert along the old spice route, traveling by worm through an area where worms were now a rarity. He'd spoken of several detours forced upon him by the presence of moisture in the sand, enough water to poison a worm. They'd arrived shortly after noon and had been brought into the stone-walled common room by guards.
The memory haunted Halleck now.
"So this is The Preacher," he'd said.
Striding around the blind man, studying him, Halleck recalled the stories about him. No stillsuit mask hid the old face in sietch, and the features were there for memory to make its comparisons. Yes, the man did look like the old Duke for whom Leto had been named. Was it a chance likeness?
"You know the stories about this one?" Halleck asked, speaking in an aside to Leto. "That he's your father come back from the desert?"
"I've heard the stories."
Halleck turned to examine the boy. Leto wore an odd stillsuit with rolled edges around his face and ears. A black robe covered it and sandboots sheathed his feet. There was much to be explained about his presence here - how he'd managed to escape once more.
"Why do you bring The Preacher here?" Halleck asked. "In Jacurutu they said he works for them."
"No more. I bring him because Alia wants him dead."
"So? You think this is a sanctuary?"
"You are his sanctuary."
All this time The Preacher stood near them, listening but giving no sign that he cared which turn their discussion took.
"He has served me well, Gurney," Leto said. "House Atreides has not lost all sense of obligation to those who serve us."
"House Atreides?"
"I am House Atreides."
"You fled Jacurutu before I could complete the testing which your grandmother ordered," Halleck said, his voice cold. "How can you assume -"
"This man's life is to be guarded as though it were your own." Leto spoke as though there were no argument and he met Halleck's stare without flinching.
Jessica had trained Halleck in many of the Bene Gesserit refinements of observation and he'd detected nothing in Leto which spoke of other than calm assurance. Jessica's orders remained, though. "Your grandmother charged me to complete your education and be sure you're not possessed."
"I'm not possessed." Just a flat statement.
"Why did you run away?"
"Namri had orders to kill me no matter what I did. His orders were from Alia."
"Are you a Truthsayer, then?"
"I am." Another flat statement filled with self-assurance.
"And Ghanima as well?"
"No."
The Preacher broke his silence then, turning his blind sockets toward Halleck but pointing at Leto. "You think you can test him?"
"Don't interfere when you know nothing of the problem or its consequences," Halleck ordered, not looking at the man.
"Oh, I know its consequences well enough," The Preacher said. "I was tested once by an old woman who thought she knew what she was doing. She didn't know, as it turned out."
Halleck looked at him then. "You're another Truthsayer?"
"Anyone can be a Truthsayer, even you," The Preacher said. "It's a matter of self-honesty about the nature of your own feelings. It requires that you have an inner agreement with truth which allows ready recognition."
"Why do you interfere?" Halleck asked, putting hand to crysknife. Who was this Preacher?
"I'm responsive to these events," The Preacher said. "My mother could put her own blood upon the altar, but I have other motives. And I do see your problem."
"Oh?" Halleck was actually curious now.
"The Lady Jessica ordered you to differentiate between the wolf and the dog, between ze'eb and ke'leb. By her definition a wolf is someone with power who misuses that power. However, between wolf and dog there is a dawn period when you cannot distinguish between them."
"That's close to the mark," Halleck said, noting how more and more people of the sietch had entered the common room to listen. "How do you know this?"
"Because I know this planet. You don't understand? Think how it is. Beneath the surface there are rocks, dirt, sediment, sand. That's the planet's memory, the picture of its history. It's the same with humans. The dog remembers the wolf. Each universe revolves around a core of being, and outward from that core go all of the memories, right out to the surface."
"Very interesting," Halleck said. "How does that help me carry out my orders?"
"Review the picture of your history which is within you. Communicate as animals would communicate."
Halleck shook his head. There was a compelling directness about this Preacher, a quality which he'd recognized many times in the Atreides, and there was more than a little hint that the man was employing the powers of Voice. Halleck felt his heart begin to hammer. Was it possible?
