Teg allowed the moment to hold for a beat, then said: "Lucilla, take Duncan into my sitting room." He nodded toward a door behind him.

Lucilla obeyed, pointedly keeping her body between Schwangyu and Duncan the whole time.

Once behind the closed door, Duncan said: "She almost called me 'the ghola.' She's really upset."

"Schwangyu has let several things slip past her guard," Lucilla said.

She glanced around Teg's sitting room, her first view of this part of his quarters: the Bashar's inner sanctum. It reminded her of her own quarters - that same mixture of orderliness and casual disarray. Reading spools lay in a clutter on a small table beside an old-fashioned chair upholstered in soft gray. The spool reader had been swung aside as though its user had just stepped out for a moment, intending to return soon. A Bashar's black uniform jacket lay across a nearby hard chair with sewing material in a small open box atop it. The jacket's cuff showed a carefully patched hole.

So he does his own mending.

This was an aspect of the famous Miles Teg she had not expected. If she had thought about it, she would have said Patrin would absorb such chores.

"Schwangyu let the attackers in, didn't she?" Duncan asked.

"Her people did." Lucilla did not hide her anger. "She has gone too far. A pact with the Tleilaxu!"

"Will Patrin kill her?"

"I don't know nor do I care!"

Outside the door, Schwangyu spoke with anger, her voice loud and quite clear: "Are we just going to wait here, Bashar?"

"You can leave anytime you wish." That was Teg.

"But I can't enter the south tunnel!"

Schwangyu sounded petulant. Lucilla knew it for something the old woman did deliberately. What was she planning? Teg must be very cautious now. He had been clever out there, revealing for Lucilla the gaps in Schwangyu's control, but they had not plumbed Schwangyu's resources. Lucilla wondered if she should leave Duncan here and return to Teg's side.

Teg said: "You can go now but I advise you not to return to your quarters."

"And why not?" Schwangyu sounded surprised, really surprised and not covering it well.

"One moment," Teg said.

Lucilla became aware of shouting at a distance. A heavy thumping explosion sounded from nearby and then another one more distant. Dust sifted from the cornice above the door to Teg's sitting room.

"What was that?" Schwangyu again, her voice overly loud.

Lucilla moved to place herself between Duncan and the wall to the hallway.

Duncan stared at the door, his body poised for defense.

"That first blast was what I expected them to do." Teg again. "The second, I fear, was what they did not expect."

A whistle piped nearby loud enough to cover something Schwangyu said.

"That's it Bashar!" Patrin.

"What is happening?" Schwangyu demanded.

"The first explosion, dear Reverend Mother, was your quarters being destroyed by our attackers. The second explosion was us destroying the attackers."

"I just got the signal, Bashar!" Patrin again. "We got them all. They came down by floater from the no-ship just as you expected."

"The ship?" Teg's voice was full of angry demand.

"Destroyed the instant it came through the space fold. No survivors."

"You fools!" Schwangyu screamed. "Do you know what you've done?"

"I carried out my orders to protect that boy from any attack," Teg said. "By the way, weren't you supposed to be in your quarters at this hour?"

"What?"

"They were after you when they blasted your quarters. The Tleilaxu are very dangerous, Reverend Mother."

"I don't believe you!"

"I suggest you go look. Patrin, let her pass."

As she listened, Lucilla heard the unspoken argument. The Mentat Bashar had been trusted here more than a Reverend Mother and Schwangyu knew it. She would be desperate. That was clever, suggesting her quarters had been destroyed. She might not believe it, though. Foremost in Schwangyu's mind now would be the realization that both Teg and Lucilla recognized her complicity in the attack. There was no telling how many others were aware of this. Patrin knew, of course.

Duncan stared at the closed door, his head tipped slightly to the right. There was a curious expression on his face, as though he saw through the door and actually watched the people out there.

Schwangyu spoke, the most careful control in her voice. "I don't believe my quarters were destroyed." She knew Lucilla was listening.

"There is only one way to make sure," Teg said.

Clever! Lucilla thought. Schwangyu could not make a decision until she was certain whether the Tleilaxu had acted treacherously.

"You will wait here for me, then! That's an order!" Lucilla heard the swish of Schwangyu's robes as the Reverend Mother departed.

Very bad emotional control, Lucilla thought. What this revealed about Teg, though, was equally disturbing. He did it to her! Teg had kept a Reverend Mother off balance.

The door in front of Duncan swung open. Teg stood there, one hand on the latch. "Quick!" Teg said. "We must be out of the Keep before she returns."

"Out of the Keep?" Lucilla did not hide her shock.

"Quick, I say! Patrin has prepared a way for us."

"But I must -"

"You must nothing! Come as you are. Follow me or we will be forced to take you."

"Do you really think you could take a..." Lucilla broke off. This was a new Teg in front of her and she knew he would not have made such a threat unless he was prepared to carry it out.

"Very well," she said. She took Duncan's hand and followed Teg out of his quarters.

Patrin stood in the hallway looking to his right. "She's gone," the old man said. He looked at Teg. "You know what to do, Bashar?"

"Pat!"

Lucilla had never before heard Teg use the batman's diminutive name.

Patrin grinned, a gleaming full-toothed smile. "Sorry, Bashar. The excitement, you know. I'll leave you to it, then. I have my part to play."

Teg waved Lucilla and Duncan down the hallway to the right. She obeyed and heard Teg close on her heels. Duncan's hand was sweaty in her hand. He pulled free and strode beside her without looking back.

The suspensor-drop at the end of the hallway was guarded by two of Teg's own people. He nodded to them. "Nobody follows."

They spoke in unison: "Right, Bashar."

Lucilla realized as she entered the drop with Duncan and Teg that she had chosen sides in a dispute whose workings she did not fully understand. She could feel the movements of the Sisterhood's politics like a swift current of water pouring all around her. Usually, the movement remained mostly a gentle wave washing the strand, but now she sensed a great destructive surge preparing to thunder its surf upon her.

Duncan spoke as they emerged into the sorting chamber for the south pillbox.

"We should all be armed," he said.

"We will be very soon," Teg said. "And I hope you're prepared to kill anyone who tries to stop us."
