He still felt a sense of responsibility for her: the burden that came with saving someone, extending and utterly changing their life. She used to look at him, in the days when she shared a city home with him and Vargos and the servants the Chancellor's eunuchs had assigned to him, and there had been questions in her eyes that made him deeply uneasy. And then one night Carullus had found him drinking in The Spina and announced he was going to marry her.

A declaration that had brought them all here now, a gathering winding towards its twilit end and the bawdy, age-old songs that would precede the curtained wedding bed, sprinkled with saffron for desire.

He looked over towards Shirin again, by the far wall. Someone else had joined Pertennius now, he saw, grinning. Another smitten suitor, one had to assume. They were legion in the City. You could make up a regiment of those who longed for the Greens" dancer with an aching need that led to bad verse, musicians on her porch in the middle of the night, street fights, tablets of love bought from cheiromancers and tossed over the wall into her courtyard garden. She had shown some of these to Crispin: Spirits of the newly dead, journeyers, come now to my aid! Send sleep-destroying, soul-ravaging longing into the bed of Shirin, dancer of the Greens, that all her thoughts in the dark be of yearning for me. Let her come forth from her doors in the grey hour before sunrise and make her way boldly, unashamed, with desire, to my house…

One could be afraid and disturbed, reading such things.

Crispin had never touched her, nor had she made overtures to him that went beyond teasing intimations. He couldn't have said why, in fact: they were bound to no one and shared a secret of the half-world with no other people alive. But there was still something that kept him from seeing Zoticus's daughter in a certain light.

It might have been the bird, the memory of her father, the dark complexity of what they shared. Or the thought of how weary she must be of men pursuing her: the crowds of would-be lovers in the street, those stone tablets in the garden invoking named and nameless pagan powers, merely to bed her.

Not, Crispin had to admit, that he was above being amused just now, seeing her cornered by suitors in her own house. A third man had joined the other two. He wondered if a fight would start.

'She says she will kill you immediately after she kills these two merchants and the wretched scribe," said the bird. 'She says for me to scream in your head when I say this.

"My dear, dear Rhodian!" said a polished, rich voice at that same moment, approaching from the other side. "I understand you intervened earlier to save this visitor to our city from harm. It was very good of you."

Crispin turned, saw the Master of the Senate with with his wife, the Bassanid beside them. Plautus Bonosus was well known, both for his private weaknesses and his public dignity. The Senate was a purely symbolic body but Bonosus was said to conduct its affairs with style and order, and he was known for a man of discretion. His handsome second wife was impeccably proper, still young, but modest and dignified before her time. It crossed Crispin's mind briefly to wonder what-if anything- she did co salve herself while her husband was out at night with boys. He couldn't readily imagine her yielding to passions. She smiled politely now at the two chariot-racers nearby, in the midst of their admirers. Both of them bowed to her and to the Senator. A little distracted, Scortius took a moment to resume the thread of his argument.

Crispin saw Pardos detach himself from those around the charioteers and come nearer. There had been changes here in half a year, but these he would sort through when he had time alone with his former apprentice. He did know that his feelings when he'd seen that it was Pardos on the ladder this morning had been those of unalloyed pleasure.

It was rare to find or feel anything unalloyed here amid the mazelike intricacies of Valerius's city. A reason he still preferred to try to live on his scaffolds overhead, with gold and coloured glass and an image of the world to make. A wish, but he knew the City and himself well enough by now to realize it wouldn't happen. Sarantium was not a place in which one found refuge, even in pursuit of a vision. The world claimed you here, caught you up in the swirling. As now.

He nodded respectfully to Bonosus and his wife and murmured, "I understand you might have a personal reason for wishing to make matters right with this physician. I am happy to leave the affair in your hands, it our eastern friend'-he looked politely at the doctor-'is willing to have it so."

The Bassanid, a prematurely greying, rather formal man, nodded his head. "I am content," he said, his Sarantine really quite good. "The Senator has been generous enough to offer me a residence while I conduct my researches here. I shall leave it to him and to those more versed than I in the justice of Sarantium to determine what should be done with those who killed my servant."

Crispin kept his expression innocent as he nodded his head. The Bassanid was being bribed, of course-the house was a first instalment. The boy would be given some penance to perform by his father, the dead servant buried quickly in a grave outside the walls.

Curse-tablets would be thrown there by night. The racing season was starting soon: the cheiromancers and other self-declared traffickers in half-world power were already busy with maledictions against horses and men-and defences against the same. A charlatan could be paid to invoke a broken leg for a celebrated horse, and then be paid to provide protection for that same animal a day later. The burial place of a murdered pagan Bassanid, Crispin thought, would probably be said to contain even greater power than the usual run of graves.

"Justice will be done," said Bonosus soberly.

"I rely upon it," said the Bassanid. He looked to Pardos. "We will meet again? I am in your debt and would like to repay your courage." A stiff man, Crispin thought, but courteous enough, knew the things to say.

"No need for that, but my name is Pardos," said the young man. It’d be easy enough to find in the Sanctuary, if Crispin doesn't kill me for setting tesserae at the wrong angle."

"Don't set them at the wrong angle," Crispin said. The Senator's mouth quirked.

"I am Rustem of Kerakek," said the Bassanid, "here to meet my western colleagues, share what I know, and obtain what further learning I can, for the better treatment of my own patients." He hesitated, then allowed himself a smile, for the first time. "I have travelled in the east. It seemed time to journey west."

"He will be living in one of my houses," Plautus Bonosus said. "The one with the two round windows, in Khardelos Street. We are honoured, of course."

Crispin felt himself go suddenly very cold. A wind seemed to pass into him: chill, damp air from the half-world, touching the mortal heart.

"Rustem. Khardelos Street," he repeated, stupidly.

"You know it?" the Senator smiled.

"I… have heard the name." He swallowed.

'Shirin, I will not say that!" he heard inwardly, still struggling with a sudden fear. There was a silence, then Danis again: 'You cannot possibly expect me to…

"It is a pleasant house," the Senator was saying. "A little small for a family, but near the walls, which was convenient in the days when I was travelling more."

Crispin nodded distractedly. Then heard: 'She says to tell you that you arc to imagine her hands right now, as you stand before this jaded boychaser and his too-prim wife. Think of her fingers slipping your tunic up from behind and then sliding back down along your skin, inside your undergarments. Think of them now, lightly touching your naked flesh, arousing you. She says to say that… Shirin! No!
