Within her skull, Alia heard a rumbling voice: "Exactly!"
Shut up! Shut up! Shut up! she thought. A dangerous mistake beckoned her in these moments and she could not recognize its outlines. All she could sense was the danger. Idaho had to help her out of this predicament. He was a mentat. Mentats were necessary. The human-computer replaced the mechanical devices destroyed by the Butlerian Jihad. Thou shalt not make a machine in the likeness of a human mind! But Alia longed now for a compliant machine. They could not have suffered from Idaho's limitations. You could never distrust a machine.
Alia heard Irulan's drawling voice.
"A feint within a feint within a feint within a feint," Irulan said. "We all know the accepted pattern of attack upon power. I don't blame Alia for her suspicions. Of course she suspects everyone - even us. Ignore that for the moment, though. What remains as the prime arena of motives, the most fertile source of danger to the Regency?"
"CHOAM," Idaho said, his voice mentat-flat.
Alia allowed herself a grim smile. The Combine Honnete Ober Advancer Mercantiles! But House Atreides dominated CHOAM with fifty-one percent of its shares. The Priesthood of Muad'Dib held another five percent, pragmatic acceptance by the Great Houses that Dune controlled the priceless melange. Not without reason was the spice often called "the secret coinage." Without melange, the Spacing Guild's heighliners could not move. Melange precipitated the "navigation trance" by which a translight pathway could be "seen" before it was traveled. Without melange and its amplification of the human immunogenic system, life expectancy for the very rich degenerated by a factor of at least four. Even the vast middle class of the Imperium ate diluted melange in small sprinklings with at least one meal a day.
But Alia had heard the mentat sincerity in Idaho's voice, a sound which she'd been awaiting with terrible expectancy.
CHOAM. The Combine Honnete was much more than House Atreides, much more than Dune, much more than the Priesthood or melange. It was inkvines, whale fur, shigawire, Ixian artifacts and entertainers, trade in people and places, the Hajj, those products which came from the borderline legality of Tleilaxu technology; it was addictive drugs and medical techniques; it was transportation (the Guild) and all of the supercomplex commerce of an empire which encompassed thousands of known planets plus some which fed secretly at the fringes, permitted there for services rendered. When Idaho said CHOAM, he spoke of a constant ferment, intrigue within intrigue, a play of powers where the shift of one duodecimal point in interest payments could change the ownership of an entire planet.
Alia returned to stand over the two seated on the divans. "Something specific about CHOAM bothers you?" she asked.
"There's always the heavy speculative stockpiling of spice by certain Houses," Irulan said.
Alia slapped her hands against her own thighs, then gestured at the embossed spice-paper beside Irulan. "That demand doesn't intrigue you, coming as it does -"
"All right!" Idaho barked. "Out with it. What're you withholding? You know better than to deny the data and still expect me to function as -"
"There has been a recent very significant increase in trade for people with four specific specialties," Alia said. And she wondered if this would be truly new information for this pair. "Which specialties?" Irulan asked.
"Swordmasters, twisted mentats from Tleilax, conditioned medics from the Suk school, and fincap accountants, most especially the latter. Why would questionable bookkeeping be in demand right now?" She directed the question at Idaho.
Function as a mentat he thought. Well, that was better than dwelling on what Alia had become. He focused on her words, replaying them in his mind mentat fashion. Swordmasters? That had been his own calling once. Swordmasters were, of course, more than personal fighters. They could repair force shields, plan military campaigns, design military support facilities, improvise weapons. Twisted mentats? The Tleilaxu persisted in this hoax, obviously. As a mentat himself, Idaho knew the fragile insecurity of Tleilaxu twisting. Great Houses which bought such mentats hoped to control them absolutely. Impossible! Even Piter de Vries, who'd served the Harkonnens in their assault on House Atreides, had maintained his own essential dignity, accepting death rather than surrender his inner core of selfdom at the end. Suk doctors? Their conditioning supposedly guaranteed them against disloyalty to their owner-patients. Suk doctors came very expensive. Increased purchase of Suks would involve substantial exchanges of funds.
Idaho weighed these facts against an increase in fincap accountants.
"Prime computation," he said, indicating a heavily weighted assurance that he spoke of inductive fact. "There's been a recent increase in wealth among Houses Minor. Some have to be moving quietly toward Great House status. Such wealth could only come from some specific shifts in political alignments."
"We come at last to the Landsraad," Alia said, voicing her own belief.
"The next Landsraad session is almost two standard years away," Irulan reminded her.
"But political bargaining never ceases," Alia said. "And I'll warrant some among those tribal signatories -" She gestured at the paper beside Irulan. "- are among the Houses Minor who've shifted their alignment."
"Perhaps," Irulan said.
"The Landsraad," Alia said. "What better front for the Bene Gesserits? And what better agent for the Sisterhood than my own mother?" Alia planted herself directly in front of Idaho. "Well, Duncan?"
Why not function as a mentat? Idaho asked himself. He saw the tenor of Alia's suspicions now. After all, Duncan Idaho had been personal house guard to the Lady Jessica for many years.
