"Careful, Alia," Idaho said. "Our enemies would like nothing better than to make us appear monstrous. No matter how many legions you command, power ultimately rides on popular sufferance in an empire as scattered as this one."

"Popular sufferance?" Irulan asked.

"You mean Great House sufferance," Alia said.

"And how many Great Houses will we face under this new alliance?" Idaho asked. "Money is collecting in strange places!"

"The fringes?" Irulan asked.

Idaho shrugged. It was an unanswerable question. All of them suspected that one day the Tleilaxu or technological tinkerers on the Imperial fringes would nullify the Holtzmann Effect. On that day, shields would be useless. The whole precarious balance which maintained planetary feudatories would collapse.

Alia refused to consider that possibility. "We'll ride with what we have," she said. "And what we have is a certain knowledge throughout the CHOAM directorate that we can destroy the spice if they force us to it. They won't risk that."

"Back to CHOAM again," Irulan said.

"Unless someone has managed to duplicate the sandtrout-sandworm cycle on another planet," Idaho said. He looked speculatively at Irulan, excited by this question. "Salusa Secundus?"

"My contacts there remain reliable," Irulan said. "Not Salusa."

"Then my answer stands," Alia said, staring at Idaho. "We ride with what we have."

My move, Idaho thought. He said: "Why'd you drag me away from important work? You could've worked this out yourself."

"Don't take that tone with me!" Alia snapped.

Idaho's eyes went wide. For an instant, he'd seen the alien on Alia's face, and it was a disconcerting sight. He turned his attention to Irulan, but she had not seen - or gave that appearance.

"I don't need an elementary education," Alia said, her voice still edged with alien anger.

Idaho managed a rueful smile, but his breast ached.

"We never get far from wealth and all of its masks when we deal with power," Irulan drawled. "Paul was a social mutation and, as such, we have to remember that he shifted the old balance of wealth."

"Such mutations are not irreversible," Alia said, turning away from them as though she'd not exposed her terrible difference. "Wherever there's wealth in this empire, they know this."

"They also know," Irulan said, "that there are three people who could perpetuate that mutation: the twins and..." She pointed at Alia.

Are they insane, this pair? Idaho wondered.

"They will try to assassinate me!" Alia rasped.

And Idaho sat in shocked silence, his mentat awareness whirling. Assassinate Alia? Why? They could discredit her too easily. They could cut her out of the Fremen pack and hunt her down at will. But the twins, now... He knew he was not in the proper mentat calm for such an assessment, but he had to try. He had to be as precise as possible. At the same time, he knew that precise thinking contained undigested absolutes. Nature was not precise. The universe was not precise when reduced to his scale; it was vague and fuzzy, full of unexpected movements and changes. Humankind as a whole had to be entered into this computation as a natural phenomenon. And the whole process of precise analysis represented a chopping off, a remove from the ongoing current of the universe. He had to get at that current, see it in motion.

"We were right to focus on CHOAM and the Landsraad," Irulan drawled. "And Duncan's suggestion offers a first line of inquiry for -"

"Money as a translation of energy can't be separated from the energy it expresses," Alia said. "We all know this. But we have to answer three specific questions: When? Using what weapons? Where?"

The twins... the twins, Idaho thought. It's the twins who're in danger, not Alia.

"You're not interested in who or how?" Irulan asked.

"If House Corrino or CHOAM or any other group employs human instruments on this planet," Alia said, "we stand a better than sixty percent chance of finding them before they act. Knowing when they'll act and where gives us a bigger leverage on those odds. How? That's just asking what weapons?"

Why can't they see it as I see it? Idaho wondered.

"All right," Irulan said. "When?"

"When attention is focused on someone else," Alia said.

"Attention was focused on your mother at the Convocation," Irulan said. "There was no attempt."

"Wrong place," Alia said.

What is she doing? Idaho wondered.

"Where, then?" Irulan asked.

"Right here in the Keep," Alia said. "It's the place where I'd feel most secure and least on my guard."

"What weapons?" Irulan asked.

"Conventional - something a Fremen might have on his person: poisoned crysknife, maula pistol, a -"

"They've not tried a hunter-seeker in a long while," Irulan said.

"Wouldn't work in a crowd," Alia said. "There'll have to be a crowd."

"Biological weapon?" Irulan asked.

"An infectious agent?" Alia asked, not masking her incredulity. How could Irulan think an infectious agent would succeed against the immunological barriers which protected an Atreides?

"I was thinking more in the line of some animal," Irulan said. "A small pet, say, trained to bite a specific victim, inflicting a poison with its bite."

"The House ferrets will prevent that," Alia said.

"One of them, then?" Irulan asked.

"Couldn't be done. The House ferrets would reject an outsider, kill it. You know that."

"I was just exploring possibilities in the hope that -"

"I'll alert my guards," Alia said.

As Alia said guards, Idaho put a hand over his Tleilaxu eyes, trying to prevent the demanding involvement which swept over him. It was Rhajia, the movement of Infinity as expressed by Life, the latent cup of total immersion in mentat awareness which lay in wait for every mentat. It threw his awareness onto the universe like a net, falling, defining the shapes within it. He saw the twins crouching in darkness while giant claws raked the air about them.

"No," he whispered.

"What?" Alia looked at him as though surprised to find him still there. He took his hand from his eyes.

"The garments that House Corrino sent?" he asked. "Have they been sent on to the twins?"

"Of course," Irulan said. "They're perfectly safe."

"No one's going to try for the twins at Sietch Tabr," Alia said. "Not with all of those Stilgar-trained guards around."

Idaho stared at her. He had no particular datum to reinforce an argument based on mentat computation, but he knew. He knew. This thing he'd experienced came very close to the visionary power which Paul had known. Neither Irulan nor Alia would believe it, coming from him.

"I'd like to alert the port authorities against allowing the importation of any outside animals," he said.

"You're not taking Irulan's suggestion seriously," Alia protested.

"Why take any chances?" he asked.

"Tell that to the smugglers," Alia said. "I'll put my dependence on the House ferrets."

Idaho shook his head. What could House ferrets do against claws the size of those he envisioned? But Alia was right. Bribes in the right places, one acquiescent Guild navigator, and anyplace in the Empty Quarter became a landing port. The Guild would resist a front position in any attack on House Atreides, but if the price were high enough... Well, the Guild could only be thought of as something like a geological barrier which made attacks difficult, but not impossible. They could always protest that they were just "a transportation agency." How could they know to what use a particular cargo would be put?

Alia broke the silence with a purely Fremen gesture, a raised fist with thumb horizontal. She accompanied the gesture with a traditional expletive which meant, "I give Typhoon Conflict." She obviously saw herself as the only logical target for assassins, and the gesture protested a universe full of undigested threats. She was saying she would hurl the death wind at anyone who attacked her.
