"Why?"
Siona snapped the question at him without formality.
Kobat jerked his head around, a quick movement which fixed his gaze on her masked face. "There has been an attempt on the God Emperor's life. He traced the weapon to me."
Siona's companions opened a space between her and the ex-Ambassador, clearly signaling that they deferred to her.
"Then why didn't he kill you?" she demanded.
"I think he is telling me that I am not worth killing. There is also the fact that he uses me now to carry a message to Ix."
"What message?" Siona moved through the cleared space to stop within two paces of Kobat. She recognized the sexual alertness in him as he studied her body.
"You are Moneo's daughter," he said.
Soundless tension exploded across the room. Why did he reveal that he recognized her? Who else did he recognize here? Kobat did not appear the fool. Why had he done this?
"Your body, your voice and your manner are well known here in Onn," he said. "That mask is a foolishness."
She ripped the mask from her head and smiled at him. "I agree. Now answer my question."
She heard Nayla move up close on her left; two more aides chosen by Nayla came up beside her.
Siona saw the moment of realization come over Kobat his death if he failed to satisfy her demands. His voice did not lose its tight control but he spoke slower, choosing his words more carefully.
"The God Emperor has told me that he knows about an agreement between Ix and the Guild. We are attempting to make a mechanical amplifier of... those Guild navigational talents which presently rely on melange."
"In this room we call him the Worm," Siona said. "What would your Ixian machine do?"
"You are aware that Guild Navigators require the spice before they can see the safe path to traverse?"
"You would replace the navigators with a machine?"
"It may be possible."
"What message do you carry to your people concerning this machine?"
"I am to tell my people that they may continue the project only if they send him daily reports on their progress."
She shook her head. "He needs no such reports! That's a stupid message."
Kobat swallowed no longer concealing nervousness.
"The Guild and the Sisterhood are excited by our project," he said. "They are participating."
Siona nodded once. "And they pay for their participation by sharing spice with Ix."
Kobat glared at her. "It's expensive work and we need the spice for comparative testing by Guild Navigators."
"It is a lie and a cheat," she said. "Your device will never work and the Worm knows it."
"How dare you accuse us of..."
"Be still! I have just told you the real message. The Worm is telling you Ixians to continue cheating the Guild and the Bene Gesserit. It amuses him."
"It could work!" Kobat insisted.
She merely smiled at him. "Who tried to kill the Worm?"
"Duncan Idaho."
Nayla gasped. There were other small signs of surprise around the room, a frown, an indrawn breath.
"Is Idaho dead?" Siona asked.
"I presume so, but the... ahhh, Worm refuses to confirm it."
"Why do you presume him dead?"
"The Tleilaxu have sent another Idaho ghola."
"I see."
Siona turned and signaled to Nayla. who went to the side of the room and returned with a slim package wrapped in pink Suk paper, the kind of paper shopkeepers used to enclose small purchases. Nayla handed the package to Siona.
"This is the price of our silence," Siona said, extending the package to Kobat. "This is why Topri was permitted to bring you here tonight."
Kobat took the package without removing his attention from her face.
"Silence?" he asked.
"We undertake not to inform the Guild and Sisterhood that you are cheating them."
"We are not cheat..."
"Don't be a fool!"
Kobat tried to swallow in a dry throat. Her meaning had become plain to him: true or not, if the rebellion spread such a story it would be believed. It was "common sense" as Topri was fond of saying.
Siona glanced at Topri who stood just behind Kobat. No one joined this rebellion for reasons of "common sense." Did Topri not realize that his "common sense" might betray him? She returned her attention to Kobat.
"What's in this package?" he asked.
Something in the way he asked it told Siona he already knew.
"That is something I am sending to Ix. You will take it there for me. That is copies of two volumes we removed from the Worm's fortress."
Kobat stared down at the package in his hands. It was obvious that he wanted to drop the thing, that his venture into rebellion had loaded him with a burden more deadly than he had expected. He shot a scowling glance at Topri which said as though he had spoken it: "Why didn't you warn me?"
"What..." He brought his gaze back to Siona, cleared his throat. "What's in these... volumes?"
"Your people may tell us that. We think they are the Worm's own words, written in a cipher which we cannot read."
"What makes you think we..."
"You Ixians are clever at such things."
"And if we fail?"
She shrugged. "We will not blame you for that. However, should you use those volumes for any other purpose or fail to report a success fully..."
"How can anyone be sure we..."
"We will not depend only on you. Others will get copies. I think the Sisterhood and the Guild will not hesitate to try deciphering those volumes."
