A grubby sock lay fallen on the floor of the corridor; she turned to say something to the monk, but he had already disappeared into the shadows.

The Hall Dolorous was vast, dark and unechoing. Its ceiling lost in darkness, its walls shrouded in great dull flags and faded banners which vanished into a hazy distance, the enormous space felt bitter cold and smelled of charnel smoke. Sharrow shivered and held her scented scarf up to her nose again as she crossed the Hall’s width, her chain clicking along the floor-track with a chittering sound like a monstrous insect.

Breyguhn sat in a high-backed stone chair at a massive granite table which looked capable of supporting a small house. A similar chair was stationed on the far side of the table from her, seven metres away. Above Breyguhn, a slab of crystal larger than the table loomed out of the shadows, hiding the Hall’s ceiling. The streaked, canted window shed a rheumy yellow light down onto the surface of the granite platform.

Breyguhn’s severe face looked even paler than Sharrow remembered; her hair was tightly bunned and she wore a loose, slate-grey shift made from some coarse, thick material.

Sharrow satin the vacant stone chair, legs dangling. Breyguhn’s dark eyes regarded her.

“Sharrow,” she said, her voice flat and faint, seemingly smothered by the pervasive silence of the Hall.

“Breyguhn,” Sharrow nodded. “How are you?”

“I am here.”

“Apart from that,” she said levelly.

“There is no apart from that.”

Breyguhn brought her hands up from her lap to lay her forearms on the cold polished surface of the table, palms up. “What is it you want again? I think they told me but I’ve forgotten.”

Breyguhn was two years younger than Sharrow. She was broader built and a little shorter, with eyes deep set in a face that had once given the impression of strength but now looked pinched and worn.

“I need to find Cenuij,” Sharrow told her. “And… you might be able to help me look for something; an Antiquity.”

“What do you want from Cenuij?” Breyguhn sounded wary.

“The Huhsz have been granted their Passports; they’re about to start hunting me. I need Cenuij on my side.”

Breyguhn sneered. “You’ll be lucky.”

“If he won’t come with me voluntarily, the Huhsz will force him to work with them. They’ll use him to find me.”

Breyguhn’s eyes went wide. “Maybe he’d like that.”

Sharrow shrugged. “Maybe,” she said. “Maybe not, but at the very least, I have to warn him that when the Huhsz find I’ve gone, they might come looking for him.” Sharrow nodded at Breyguhn. “You’re the only person who seems to know exactly where he is.”

Breyguhn shrugged. “I haven’t seen Cenuij for six years,” she said. “They don’t allow visits from loved ones here. They only allow visitors one doesn’t want to see; visitors guaranteed to torment one.” Her mouth twisted humourlessly.

“But you’re in contact with him,” Sharrow said. “He writes.”

Breyguhn smiled, as if with difficulty, out of practice. “Yes, he writes; real letters, on paper. So much more romantic…” Her grin broadened, and Sharrow felt her skin crawl. “They come from Lip City.”

“But does he live there?”

“Yes. I thought you knew.”

“Whereabouts in the city?”

“Isn’t he registered with City Hall?” Breyguhn smiled.

Sharrow frowned. “The place is a barrio, Brey; you know damn well. There are quarters that don’t even have electricity.”

Breyguhn’s smile was wintery. “And whose fault is that, Sharrow?”

“Just tell me where Cenuij is, Brey.”

Breyguhn shrugged. “I have no idea. I have to send my letters post restante.” She looked down at the table top. Her smile faded quickly. “He sounds lonely,” she said in a small voice. “I think he has other loves now, but he sounds lonely.”

“Isn’t there anything in any of his letters-”

Breyguhn looked up, gaze sharp. “Echo Street,” she said suddenly.

“Echo Street.”

“Don’t tell him I told you.”

“All right.”

Breyguhn shivered. She drew her arms off the surface of the granite table and let her hands fall to her lap again. She looked uncertain for a moment. “What else was there?”

“Information on an Antiquity.”

“Had you a particular one in mind?”

“The U.P.”

Breyguhn put her head back and laughed; a faint echo of the noise came back, seconds later, from overhead. She frowned and put one hand over her mouth. “Oh dear; I’ll pay for that later.” She squinted at Sharrow. “You want to go after the Universal Principles?”

“Yes.”

“Why,” Breyguhn said. “That’s the price the Brothers have set for my release; are you doing this for me, Sharrow?” she asked, her voice heavy with sarcasm. “How sweet.”

“It’s for both of us,” Sharrow said. She found herself dropping her voice even though she knew that it made no difference if the Sea House’s masters were listening in. “I need the bit of… incidental information, the directions the work is supposed to contain. Once I have that, I guarantee I’ll give the book to the Sad Brothers. You’ll be free to leave here.”

Breyguhn put one hand fanned across her chest and fluttered her eyelids dramatically. “And why do you think I can help?” she asked, her voice artificially high.

Sharrow gritted her teeth. “Because,” she said, “the last time I was here you told me they let you use the libraries. You thought you were on the trail at last. And-”

“Yes.” Breyguhn’s eyes narrowed. “And I sent you,” she hissed, “a letter.” She glanced round then leaned closer. “I told you I had found the way,” she whispered. “The means to discover… that book.”

Sharrow sighed. She remembered the letter from Breyguhn; handwritten, barely legible, confused and full of wild accusations, bizarre, rambling political tirades and screeds of incomprehensible pseudo-religious rantings. Breyguhn’s claim in the course of it that she knew how to find the lost book had been mentioned almost as an aside in the midst of a manically passionate attack on the legal-political system in general and the World Court in particular. Sharrow had dismissed it at the time as literally incredible. “Yes, Brey,” she said. “And I wrote back to tell you I wasn’t in the Antiquities business any more.”

“But I told you only you could find it!” Breyguhn spat the words out.

Sharrow nodded slowly, looking away. “Indeed you did.”

“And you didn’t believe me.”

Sharrow shrugged. “You were the one who thought the book was here.”

“Maybe it is,” Breyguhn said, eyes narrowing. “Maybe they’re all here; the U.P., the Gnost, the Analysis of Major Journeys; all of them; every damn book Goltei’s ever had and then lost in ten thousand years and more. They might all be here; a million Uniques, a million treasures, all buried here, lost, thrown away to rot on the dung-pile this place is.” She directed a small, thin smile at Sharrow. “I haven’t found them, but they might be here. Even the Brothers themselves don’t know. The House has secrets even they haven’t guessed at.”

“I’m sure,” Sharrow said, tapping her fingers on the granite table. “Now-”

Breyguhn’s eyes narrowed. “We both know what the book’s supposed to lead to; what are you going to do with that?”

“Give it to the Huhsz,” Sharrow said. She gave a small laugh, glancing round the vast shadows around them. “We both have… eccentric cults to pay off.” She settled her gaze on Breyguhn again. “So. What have you got? What is it you know that-?”

“Blood fealty,” Breyguhn said suddenly.

Sharrow frowned. “What?”

“Blood fealty,” Breyguhn repeated. “Grandfather’s inner circle of aides and servants were under genetic thrall to him; he’d had behavioural patterns programmed into them.”

“I know; it was one of the reasons the World Court fell on him from the height it did.”

“Huh,” Breyguhn sighed, eyes bright for a moment. “Yes; if he’d got to a couple of their judges, or Corp chief execs with that sort of power…” She shook her head.
