"That is not why I'm dangerous." Before she could move, he leaned across, gripped her chin in one hand, planted his lips on hers.

It was a gentle kiss, brief. He pulled away and she stared at him with a shock leavened by glimpses of spasmodic grins on the faces of her guardsmen still standing at orderly attention outside.

Alia put a finger to her lips. There'd been such a sense of familiarity about that kiss. His lips had been flesh of a future she'd seen in some prescient byway. Breast heaving, she said: "I should have you flayed."

"Because I'm dangerous?"

"Because you presume too much!"

"I presume nothing. I take nothing which is not first offered to me. Be glad I did not take all that was offered." He opened his door, slid out. "Come along. We've dallied too long on a fool's errand." He strode toward the entrance dome beyond the pad.

Alia leaped out, ran to match his stride. "I'll tell him everything you've said and everything you did," she said.

"Good." He held the door for her.

"He will order you executed," she said, slipping into the dome.

"Why? Because I took the kiss I wanted?" He followed her, his movement forcing her back. The door slid closed behind him.

"The kiss you wanted!" Outrage filled her.

"All right, Alia. The kiss you wanted, then." He started to move around her toward the drop field.

As though his movement had propelled her into heightened awareness, she realized his candor - the utter truthfulness of him. The kiss I wanted, she told herself. True.

"Your truthfulness, that's what's dangerous," she said, following him.

"You return to the ways of wisdom," he said, not breaking his stride. "A mentat could not've stated the matter more directly. Now: what is it you saw in the desert?"

She grabbed his arm, forcing him to a halt. He'd done it again: shocked her mind into sharpened awareness.

"I can't explain it," she said, "but I keep thinking of the Face Dancers. Why is that?"

"That is why your brother sent you to the desert," he said, nodding. "Tell him of this persistent thought."

"But why?" She shook her head. "Why Face Dancers?"

"There's a young woman dead out there," he said. "Perhaps no young woman is reported missing among the Fremen."

As he lay immersed in the screaming odor of the spice, staring inward through the oracular trance, Paul saw the moon become an elongated sphere. It rolled and twisted, hissing - the terrible hissing of a star being quenched in an infinite sea - down... down... down... like a ball thrown by a child.

It was gone.

This moon had not set. Realization engulfed him. It was gone: no moon. The earth quaked like an animal shaking its skin. Terror swept over him.

Paul jerked upright on his pallet, eyes wide open, staring. Part of him looked outward, part inward. Outwardly, he saw the plasmeld grillwork which vented his private room, and he knew he lay beside a stone-like abyss of his Keep. Inwardly, he continued to see the moon fall.

Out! Out!

His grillwork of plasmeld looked onto the blazing light of noon across Arrakeen. Inward - there lay blackest night. A shower of sweet odors from a garden roof nibbled at his senses, but no floral perfume could roll back that fallen moon.

Paul swung his feet to the cold surface of the floor, peered through the grillwork. He could see directly across to the gentle arc of a footbridge constructed of crystal-stabilized gold and platinum. Fire jewels from far Cedon decorated the bridge. It led to the galleries of the inner city across a pool and fountain filled with waterflowers. If he stood, Paul knew, he could look down into petals as clean and red as fresh blood whirling, turning there - disks of ambient color tossed on an emerald freshet.

His eyes absorbed the scene without pulling him from spice thralldom.

That terrible vision of a lost moon.

The vision suggested a monstrous loss of individual security. Perhaps he'd seen his civilization fall, toppled by its own pretensions.

A moon... a moon... a falling moon.

It had taken a massive dose of the spice essence to penetrate the mud thrown up by the tarot. All it had shown him was a falling moon and the hateful way he'd known from the beginning. To buy an end for the Jihad, to silence the volcano of butchery, he must discredit himself.

Disengage... disengage... disengage...

Floral perfume from the garden roof reminded him of Chani. He longed for her arms now, for the clinging arms of love and forgetfulness. But even Chani could not exorcise this vision. What would Chani say if he went to her with the statement that he had a particular death in mind? Knowing it to be inevitable, why not choose an aristocrat's death, ending life on a secret flourish, squandering any years that might have been? To die before coming to the end of willpower, was that not an aristocrat's choice?

He stood, crossed to the lapped opening in the grillwork, went out onto a balcony which looked upward to flowers and vines trailing from the garden. His mouth held the dryness of a desert march.

Moon... moon - where is that moon?

He thought of Alia's description, the young woman's body found in the dunes. A Fremen addicted to semuta! Everything fitted the hateful pattern.

You do not take from this universe, he thought. It grants what it will.

The remains of a conch shell from the seas of Mother Earth lay on a low table beside the balcony rail. He took its lustrous smoothness into his hands, tried to feel backward in Time. The pearl surface reflected glittering moons of light. He tore his gaze from it, peered upward past the garden to a sky become a conflagration - trails of rainbow dust shining in the silver sun.

My Fremen call themselves "Children of the Moon," he thought.

He put down the conch, strode along the balcony. Did that terrifying moon hold out hope of escape? He probed for meaning in the region of mystic communion. He felt weak, shaken, still gripped by the spice.

At the north end of his plasmeld chasm, he came in sight of the lower buildings of the government warren. Foot traffic thronged the roof walks. He felt that the people moved there like a frieze against a background of doors, walls, tile designs. The people were tiles! When he blinked, he could hold them frozen in his mind. A frieze.

A moon falls and is gone.

A feeling came over him that the city out there had been translated into an odd symbol for his universe. The buildings he could see had been erected on the plain where his Fremen had obliterated the Sardaukar legions. Ground once trampled by battles rang now to the rushing clamor of business.

Keeping to the balcony's outer edge, Paul strode around the corner. Now, his vista was a suburb where city structures lost themselves in rocks and the blowing sand of the desert. Alia's temple dominated the foreground; green and black hangings along its two-thousand-meter sides displayed the moon symbol of Muad'dib.

A falling moon.

Paul passed a hand across his forehead and eyes. The symbol-metropolis oppressed him. He despised his own thoughts. Such vacillation in another would have aroused his anger.

He loathed his city!

Rage rooted in boredom flickered and simmered deep within him, nurtured by decisions that couldn't be avoided. He knew which path his feet must follow. He'd seen it enough times, hadn't he? Seen it! Once... long ago, he'd thought of himself as an inventor of government. But the invention had fallen into old patterns. It was like some hideous contrivance with plastic memory. Shape it any way you wanted, but relax for a moment, and it snapped into the ancient forms. Forces at work beyond his reach in human breasts eluded and defied him.
