Muriz, nursing his injured hand, shook his head at the figure in the 'thopter, said: "My companion Behaleth has heard you. He will be as unmoving as the rock."

Knowing he had very little time until the two worked out a plan of action or their friends came to investigate, Leto spoke swiftly: "You need me, Muriz. Without me, the worms and their spice will vanish from Dune." He felt the Fremen stiffen.

"But how do you know of Shuloch?" Muriz asked. "I know they said nothing at Jacurutu."

"So you admit I'm Leto Atreides?"

"Who else could you be? But how do you -"

"Because you are here," Leto said. "Shuloch exists, therefore the rest is utter simplicity. You are the Cast Out who escaped when Jacurutu was destroyed. I saw you signal with your wings, therefore you use no device which could be overheard at a distance. You collect spice, therefore you trade. You could only trade with the smugglers. You are a smuggler, yet you are Fremen. You must be of Shuloch."

"Why did you tempt me to slay you out of hand?"

"Because you would've slain me anyway when we'd returned to Shuloch."

A violent rigidity came over Muriz's body.

"Careful, Muriz," Leto cautioned. "I know about you. It was in your history that you took the water of unwary travelers. By now this would be common ritual with you. How else could you silence the ones who chanced upon you? How else keep your secret? Batigh! You'd seduce me with gentle epithets and kindly words. Why waste any of my water upon the sand? And if I were missed as were many of the others - well, the Tanzerouft got me."

Muriz made the Horns-of-the-Worm sign with his right hand to ward off the Rihani which Leto's words called up. And Leto, knowing how older Fremen distrusted mentats or anything which smacked of them by a show of extended logic, suppressed a smile.

"Manri spoke of us at Jacurutu," Muriz said. "I will have his water when -"

"You'll have nothing but empty sand if you continue playing the fool," Leto said. "What will you do, Muriz, when all of Dune has become green grass, trees, and open water?"

"It will never happen!"

"It is happening before your eves."

Leto heard Muriz's teeth grinding in rage and frustration. Presently the man grated: "How would you prevent this?"

"I know the entire plan of the transformation," Leto said. "I know every weakness in it, every strength. Without me, Shai-Hulud will vanish forever."

A sly note returning to his voice, Muriz asked: "Well, why dispute it here? We're at a standoff. You have your knife. You could kill me, but Behaleth would shoot you."

"Not before I recovered your pistol," Leto said. "Then I'd have your 'thopter. Yes, I can fly it."

A scowl creased Muriz's forehead beneath the hood. "What if you're not who you say?"

"Will my father not identify me?" Leto asked.

"Ahhhh," Muriz said. "There's how you learned, eh? But..." He broke off, shook his head. "My own son guides him. He says you two have never... How could..."

"So you don't believe Muad'Dib reads the future," Leto said.

"Of course we believe! But he says of himself that..." Again Muriz broke off.

"And you thought him unaware of your distrust," Leto said. "I came to this exact place in this exact time to meet you, Muriz. I know all about you because I've seen you... and your son. I know how secure you believe yourselves, how you sneer at Muad'Dib, how you plot to save your little patch of desert. But your little patch of desert is doomed without me, Muriz. Lost forever. It has gone too far here on Dune. My father has almost run out of vision, and you can only turn to me."

"That blind..." Muriz stopped, swallowed.

"He'll return soon from Arrakeen," Leto said, "and then we shall see how blind he is. How far have you gone from the old Fremen ways, Muriz?"

"What?"

"He is Wadquiyas with you. Your people found him alone in the desert and brought him to Shuloch. What a rich discovery he was! Richer than a spice-vein. Wadquiyas! He has lived with you; his water mingled with your tribe's water. He's part of your Spirit River." Leto pressed the knife hard against Muriz's robe. "Careful, Muriz." Leto lifted his left hand, released the Fremen's face flap, dropped it.

Knowing what Leto planned, Muriz said: "Where would you go if you killed us both?"

"Back to Jacurutu."

Leto pressed the fleshy part of his own thumb against Muriz's mouth. "Bite and drink, Muriz. That or die."

Muriz hesitated, then bit viciously into Leto's flesh.

Leto watched the man's throat, saw the swallowing convulsion, withdrew the knife and returned it.

"Wadquiyas," Leto said. "I must offend the tribe before you can take my water."

Muriz nodded.

"Your pistol is over there." Leto gestured with his chin.

"You trust me now?" Muriz asked.

"How else can I live with the Cast Out?"

Again Leto saw the sly look in Muriz's eyes, but this time it was a measuring thing, a weighing of economics. The man turned away with an abruptness which told of secret decisions, recovered his maula pistol and returned to the wing step. "Come," he said. "We tarry too long in a worm's lair."

Muriz brought the ornithopter in over Shuloch with a practiced ease. Leto, seated beside him, felt the armed presence of Behaleth behind them. Everything went on trust now and the narrow thread of his vision to which he clung. If that failed, Allahu akbahr. Sometimes one had to submit to a greater order.

The butte of Shuloch was impressive in this desert. Its unmarked presence here spoke of many bribes and many deaths, of many friends in high places. Leto could see at Shuloch's heart a cliff-walled pan with interfringing blind canyons leading down into it. A thick growth of shadescale and salt bushes lined the lower edges of these canyons with an inner ring of fan palms, indicating the water riches of this place. Crude buildings of greenbush and spice-fiber had been built out from the fan palms. The buildings were green buttons scattered on the sand. There would live the cast out of the Cast Out, those who could go no lower except into death.

Muriz landed in the pan near the base of one of the canyons. A single structure stood on the sand directly ahead of the 'thopter: a thatch of desert vines and bejato leaves, all lined with heat-fused spice-fabric. It was the living replica of the first crude stilltents and it spoke of degradation for some who lived in Shuloch. Leto knew the place would leak moisture and would be full of night-biters from the nearby growth. So this was how his father lived. And poor Sabiha. Here would be her punishment.

At Muriz's order Leto let himself out of the 'thopter, jumped down to the sand, and strode toward the hut. He could see many people working farther toward the canyon among the palms. They looked tattered, poor, and the fact that they barely glanced at him or at the 'thopter said much of the oppression here. Leto could see the rock lip of a qanat beyond the workers, and there was no mistaking the sense of moisture in this air: open water. Passing the hut, Leto saw it was as crude as he'd expected. He pressed on to the qanat, peered down and saw the swirl of predator fish in the dark flow. The workers, avoiding his eyes, went on with clearing sand away from the line of rock openings.
