Children of Dune

Idaho looked up at her, thinking: That's awfully close to the edge with Irulan! Again he wondered why Alia had brought him back here when she knew that he was needed at Sietch Tabr if the abduction plot were to be carried off. Was it possible she'd heard about the message sent to him by The Preacher? This thought filled his breast with turmoil. How could that mendicant mystic know the secret signal by which Paul Atreides had always summoned his swordmaster? Idaho longed to leave this pointless meeting and return to the search for an answer to that question.

"There's no doubt that The Preacher has been off-planet," Alia said. "The Guild wouldn't dare deceive us in such a thing. I will have him -"

"Careful!" Irulan said.

"Indeed, have a care," Idaho said. "Half the planet believe him to be -" He shrugged. "- your brother." And Idaho hoped he had carried this off with a properly casual attitude. How had the man known that signal?

"But if he's a courier, or a spy of the -"

"He's made contact with no one from CHOAM or House Corrino," Irulan said. "We can be sure of -"

"We can be sure of nothing!" Alia did not try to hide her scorn. She turned her back on Irulan, faced Idaho. He knew why he was here! Why didn't he perform as expected? He was in Council because Irulan was here. The history which had brought a Princess of House Corrino into the Atreides fold could never be forgotten. Allegiance, once changed, could change again. Duncan's mentat powers should be searching for flaws, for subtle deviations in Irulan's behavior.

Idaho stirred, glanced at Irulan. There were times when he resented the straight-line necessities imposed on mentat performance. He knew what Alia was thinking. Irulan would know it as well. But this Princess-wife to Paul Muad'Dib had overcome the decisions which had made her less than the royal concubine, Chani. There could be no doubt of Irulan's devotion to the royal twins. She had renounced family and Bene Gesserit in dedication to the Atreides.

"My mother is part of this plot!" Alia insisted. "For what other reason would the Sisterhood send her back here at a time such as this?"

"Hysteria isn't going to help us," Idaho said.

Alia whirled away from him, as he'd known she would. It helped him that he did not have to look at that once-beloved face which was now so twisted by alien possession.

"Well," Irulan said, "the Guild can't be completely trusted for -"

"The Guild!" Alia sneered.

"We can't rule out the enmity of the Guild or the Bene Gesserit," Idaho said. "But we must assign them special categories as essentially passive combatants. The Guild will live up to its basic rule: Never Govern. They're a parasitic growth, and they know it. They won't do anything to kill the organism which keeps them alive."

"Their idea of which organism keeps them alive may be different from ours," Irulan drawled. It was the closest she ever came to a sneer, that lazy tone of voice which said: "You missed a point, mentat."

Alia appeared puzzled. She had not expected Irulan to take this tack. It was not the kind of view which a conspirator would want examined.

"No doubt," Idaho said. "But the Guild won't come out overtly against House Atreides. The Sisterhood, on the other hand, might risk a certain kind of political break which -"

"If they do, it'll be through a front: someone or some group they can disavow," Irulan said. "The Bene Gesserit haven't existed all of these centuries without knowing the value of self-effacement. They prefer being behind the throne, not on it."

Self-effacement? Alia wondered. Was that Irulan's choice?

"Precisely the point I make about the Guild," Idaho said. He found the necessities of argument and explanation helpful. They kept his mind from other problems.

Alia strode back toward the sunlit windows. She knew Idaho's blind spot; every mentat had it. They had to make pronouncements. This brought about a tendency to depend upon absolutes, to see finite limits. They knew this about themselves. It was part of their training. Yet they continued to act beyond self-limiting parameters. I should've left him at Sietch Tabr, Alia thought. It would've been better to just turn Irulan over to Javid for questioning.

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.
