talk to you for a moment, if you can spare the time."
    "Been expecting you," the fat woman replied. "Marcellinus at the Poverty said you'd been asking round after me." She looked at him as if she was thinking of buying him, then added, "Come in if you want."
    He followed her through the door into a small paved courtyard. There was a porch on one side, its timbers bowed under the weight of an enormous overgrown vine, in front of which stood two plain wooden chairs and a round table, with two cups and a wine bottle on it.
    "Drink," she said; not a suggestion or an offer, just a statement of fact. She tilted the bottle, pushed one cup across the table at him, and sat down.
    "Thanks," he said, leaving the cup where it was. "Did—what did you say his name was?"
    "Marcellinus. And no, he didn't say what you wanted to see me about. I can guess, though."
    Vaatzes nodded. "Go on, then," he said.
    "You're an engineer, aren't you?" she said, wiping her mouth on her left forefinger. "Blacksmith, metalworker, whatever. You need materials. Someone told you I used to be in business, trading east with the Cure Doce." She shook her head.
    "Whoever told you that's way behind the times. I retired. Bad knee," she added, squeezing her right kneecap. "So, sorry, can't help you."
    "Actually," Vaatzes smiled, "the man at the Poverty and Justice did tell me you'd retired, but it wasn't business I wanted to talk to you about. At least," he added, "not directly."
    "Oh." She looked at him as though he'd just slithered out of check and taken her queen. "Well, in that case, what can I do for you?"
    Vaatzes edged a little closer. "Your late husband," he said.
    "Oh. Him."
    "Yes." He picked up the wine cup but didn't drink anything. "I understand that he used to lead a mule-train out along the southern border occasionally. Is that right?" She pulled a face, as though trying to remember something unimportant from a long time ago. It was a reasonable performance, but she held it just a fraction too long. "Salt," she said. "There's some place in the desert where they dig it out of the ground. A couple of times he went down there to the market, where they take the stuff to sell it off. Thought he could make a profit but the margins were too tight. Mind you," she added, "that's got to be, what, twenty years ago, and we weren't living here then, it was while we were still in Chora. Lost a fair bit of money, one way and another."
    Vaatzes nodded. "That's more or less what I'd heard," he said. She looked up at him. "Why?" she asked. "You thinking of going into the salt business?"
    "It had crossed my mind."
    "Forget it." She waved her hand, as though swatting a fat, blind fly. "The salt trade's all tied up, has been for years. Your lot, mostly, the Mezentines. They run everything now."
    "But not twenty years ago," Vaatzes said quietly, and that made her look at him again. "And besides, even now they mostly buy through intermediaries. Cure Doce, as I understand."
    "Could be." She yawned, revealing an unexpectedly pristine set of teeth. "I never got into that particular venture very much. Knew from the outset it was a dead end. If he'd listened to me, maybe things'd be very different now." She tilted the bottle over her cup, but Vaatzes could see it was already three-quarters full. "When we were living in Chora—"
    "I expect you had something to do with it," he said mildly. "Presumably you were buying the stock he took with him to trade for the salt."
    "Could be. Can't remember." She yawned again, but she was picking at a loose thread on her sleeve. "That was my side of the business back then, yes. I'd buy the stuff in Chora, he'd take it out to wherever he was trading that year. Never worked out. Any margin I managed to make at home, he'd blow it all out in the wilderness somewhere. That's what made me throw him out, eventually."
    "I can see it must've been frustrating for you," Vaatzes said. "But to get back to the salt. Can you remember who it was he used to buy it
