"But this..." Al-Fali's head nodded toward Idaho.

"This was my loyal guardian before Alia was born," Jessica said. "Before he died saving my son's life and mine. We Atreides always honor certain obligations."

"Then you will go with me?" Idaho asked.

"Where would you take her?" al-Fali asked.

"Best that you don't know," Jessica said.

Al-Fali scowled but remained silent. His face betrayed indecision, an understanding of the wisdom in her words but an unresolved doubt of Idaho's trustworthiness.

"What of the Fedaykin who helped me?" Jessica asked.

"They have Stilgar's countenance if they can get to Tabr," Idaho said. Jessica faced al-Fali: "I command you to go there, my friend. Stilgar can use Fedaykin in the search for my grandchildren."

The old Naib lowered his gaze. "As Muad'Dib's mother commands."

He's still obeying Paul, she thought.

"We should be out of here quickly," Idaho said. "The search is certain to include this place, and that early."

Jessica rocked forward and arose with that fluid grace which never quite left the Bene Gesserit, even when they felt the pangs of age. And she felt old now after her night of flight. Even as she moved, her mind remained on that peculiar interview with her grandson. What was he really doing? She shook her head, covered the motion by adjusting her hood. It was too easy to fall into the trap of underestimating Leto. Life with ordinary children conditioned one to a false view of the inheritance which the twins enjoyed.

Her attention was caught by Idaho's pose. He stood in the relaxed preparedness for violence, one foot ahead of the other, a stance which she herself had taught him. She shot a quick look at the two young Fremen, at al-Fali. Doubts still assailed the old Fremen Naib and the two young men felt this.

"I trust this man with my life," she said, addressing herself to al-Fali. "And it is not the first time."

"My Lady," al-Fali protested. "It's just..." He glared at Idaho. "He's the husband of the Coan-Teen!"

"And he was trained by my Duke and by me," she said.

"But he's a ghola!" The words were torn from al-Fali.

"My son's ghola," she reminded him.

It was too much for a former Fedaykin who'd once pledged himself to support Muad'Dib to the death. He sighed, stepped aside, and motioned the two young men to open the curtains.

Jessica stepped through, Idaho behind her. She turned, spoke to al-Fali in the doorway. "You are to go to Stilgar. He's to be trusted."

"Yes..." But she still heard doubts in the old man's voice.

Idaho touched her arm. "We should go at once. Is there anything you wish to take?"

"Only my common sense," she said.

"Why? Do you fear you're making a mistake?"

She glanced up at him. "You were always the best 'thopter pilot in our service, Duncan."

This did not amuse him. He stepped ahead of her, moving swiftly, retracing the way he'd come. Al-Fali fell into step beside Jessica. "How did you know he came by 'thopter?"

"He wears no stillsuit," Jessica said.

Al-Fali appeared abashed by this obvious perception. He would not be silenced, though. "Our messenger brought him here directly from Stilgar's. They could've been seen."

"Were you seen, Duncan?" Jessica asked Idaho's back.

"You know better than that," he said. "We flew lower than the dune tops."

They turned into a side passage which led downward in spiral steps, debouching finally into an open chamber well-lighted by glowglobes high in the brown rock. A single ornithopter sat facing the far wall, crouched there like an insect waiting to spring. The wall would be false rock, then - a door opening onto the desert. As poor as this sietch was, it still maintained the instruments of secrecy and mobility.

Idaho opened the ornithopter's door for her, helped her into the right-hand seat. As she moved past him, she saw perspiration on his forehead where a lock of the black goat-hair lay tumbled. Unbidden, Jessica found herself recalling that head spouting blood in a noisy cavern. The steely marbles of the Tleilaxu eyes brought her out of that recollection. Nothing was as it seemed anymore. She busied herself fastening her seatbelt.

"It's been along time since you've flown me, Duncan," she said.

"Long and far time," he said. He was already checking the controls.

Al-Fali and the two younger Fremen waited beside the controls to the false rock, prepared to open it.

"Do you think I harbor doubts about you?" Jessica asked, speaking softly to Idaho.

Idaho kept his attention on an engine instrument, ignited the impellers and watched a needle move. A smile touched his mouth, a quick and harsh gesture in his sharp features, gone as quickly as it had come.

"I am still Atreides," Jessica said. "Alia is not."

"Have no fear," he grated. "I still serve the Atreides."

"Alia is no longer Atreides," Jessica repeated.

"You needn't remind me!" he snarled. "Now shut up and let me fly this thing."

The desperation in his voice was quite unexpected, out of keeping with the Idaho she'd known. Putting down a renewed sense of fear, Jessica asked: "Where are we going, Duncan? You can tell me now."

But he nodded to al-Fali and the false rock opened outward into bright silvery sunlight. The ornithopter leaped outward and up, its wings throbbing with the effort, the jets roaring, and they mounted into an empty sky. Idaho set a southwesterly course toward Sahaya Ridge which could be seen as a dark line upon the sand.

Presently he said: "Do not think harshly of me, My Lady."

"I haven't thought harshly of you since that night you came into our Arrakeen great hall roaring drunk on spice-beer," she said. But his words renewed her doubts, and she fell into the relaxed preparedness of complete prana-bindu defense.

"I remember that night well," he said. "I was very young... inexperienced."

"But the best swordmaster in my Duke's retinue."

"Not quite, My Lady. Gurney could best me six times out of ten." He glanced at her. "Where is Gurney?"

"Doing my bidding."

He shook his head.

"Do you know where we're going?" she asked.

"Yes, My Lady."

"Then tell me."

"Very well. I promised that I would create a believable plot against House Atreides. Only one way, really, to do that." He pressed a button on the control wheel and cocoon restraints whipped from Jessica's seat, enfolded her in unbreakable softness, leaving only her head exposed. "I'm taking you to Salusa Secundus," he said. "To Farad'n."

In a rare, uncontrolled spasm, Jessica surged against the restraints, felt them tighten, easing only when she relaxed, but not before she felt the deadly shigawire concealed in the protective sheathing.

"The shigawire release has been disconnected," he said, not looking at her. "Oh yes, and don't try Voice on me. I've come a long way since the days when you could move me that way." He looked at her. "The Tleilaxu armored me against such wiles."

"You're obeying Alia," Jessica said, "and she -"

"Not Alia," he said. "We do The Preacher's bidding. He wants you to teach Farad'n as once you taught... Paul."

Jessica remained in frozen silence, remembering Leto's words, that she would find an interesting student. Presently she said: "This Preacher - is he my son?"

Idaho's voice seemed to come from a great distance: "I wish I knew."
