He drinks deeply, then sets the goblet carefully on the floor. He crosses the room and mounts a step and peers through a slot window cut in the deep wall.

I'm sure we're alone now. Drink up; I'll fetch the krrf. He is gone/or less than a minute, and returns with a heavy brick wrapped in soft leather.

Caronne's finest, pure black, unadulterated. He unfolds the package: ebony block embossed all over its surface with a foreign seal. Try some?

He nods. 'A wise vintner who avoids his wares.' You have the gold?

He weighs the bag in his hand. This is not enough. Not by half.

He listens and hands back the gold. Be reasonable. If you feel you can't trust my assay, take a small amount back to Ranke; have anyone test it. Then bring me the price we established.

The other man suddenly stands and claws at his falchion, but it barely clears its sheath, then clatters on the marble floor. He falls to his hands and knees, trembling, stutters a few words, and collapses.

No, not a spell, though nearly as swift, don't you think? That's the virtue ofcoadjutant poisons. The first ingredient you had along with everyone else, in the sauce for the sweetmeats. Everyone but me. The second part was in the wine, part of its sweetness.

He runs his thumbnail along the block, collecting a pinch of krrf, which he rubs between thumb and forefinger and then sniffs. You really should try it. It makes you feel young and brave. But then you are young and brave, aren't you.

He carefully wraps the krrf up and retrieves the gold. Excuse me. I have to go change. At the door he hesitates. The poison is not fatal; it only leaves you paralysed for a while. Surgeons use it.

The man stares at the floor for a long time. He is conscious of drooling, and other loss of control.

When the host returns, he is barely recognizable. Instead of the gaudy robe, he wears a patched and stained houppelande with a rope for a belt. The pomaded white mane is gone: his bald scalp is creased with a webbed old scar from a swordstroke. His left thumb is missing from the second joint. He smiles, and shows almost as much gap as tooth.

I am going to treat you kindly. There are some who would pay well to use your helpless body, and they would kill you afterwards.

He undresses the limp man, clucking, and again compliments himself for his charity, and the man for his well-kept youth. He lifts the grate in the fireplace and drops the garment down the shaft that serves for disposal of ashes.

In another part of town, I'm known as One-Thumb; here, I cover the stump with a taxidermist's imitation. Convincing, isn't it? He lifts the man easily and carries him through the main door. No fault of yours, of course, but you're distantly related to the magistrate who had my thumb off. The barking of the dogs grows louder as they descend the stairs.

Here we are. He pushes open the door to the kennels. The barking quiets to pleading whines. Ten fighting hounds, each in an individual run, up against its feeding trough, slavering politely, yawning grey sharp fangs.,

We have to feed them separately, of course. So they don't hurt each other.

At the far end of the room is a wooden slab at waist-level, with channels cut in its surface leading to hanging buckets. On the wall above it, a rack with knives, cleavers, and a saw.

He deposits the mute staring man on the slab and selects a heavy cleaver.

I'm sorry, Amar. I have to start with the feet. Otherwise it's a terrible mess.

There are philosophers who argue that there is no such thing as evil qua evil: that, discounting spells (which of course relieve an individual of responsibility), when a man commits an evil deed he is the victim himself, the slave of his progeniture and nurturing. Such philosophers might profit by studying Sanctuary.

Sanctuary is a seaport, and its name goes back to a time when it provided the only armed haven along an important caravan route. But the long war ended, the caravans abandoned that route for a shorter one, and Sanctuary declined in status - but not in population, because for every honest person who left to pursue a normal life elsewhere, a rogue drifted in to pursue his normal life.

Now, Sanctuary is still appropriately named, but as a haven for the lawless. Most of them, and the worst of them, are concentrated in that section of town known as the Maze, a labyrinth of streets and nameless alleys and no churches. There is communion, though, of a rough kind, and much of it goes on in a tavern named the Vulgar Unicorn, which features a sign in the shape of that animal improbably engaging itself, and is owned by the man who usually tends bar on the late shift, an ugly sort of fellow by the name of One-Thumb.

One-Thumb finished feeding the dogs, hosed the place down, and left his estate by way of a long tunnel, that led from his private rooms to the basement of the Lily Garden, a respectable whorehouse a few blocks from the Maze.

He climbed the long steps up from the basement and was greeted by a huge eunuch with a heavy glaive balanced insolently over his shoulder.

'Early today, One-Thumb.'

'Sometimes I like to check on the help at the Unicom.'

'Surprise inspection?'

'Something like that. Is your mistress in?'

'Sleeping. You want a wench?'

'No, just business.'

The eunuch inclined his head. 'That's business.'

'Tell her I have what she asked for, and more, if she can afford it. When she's free. If I'm not at the Unicorn, I'll leave word as to where we can meet.'

'I know what it is,' the eunuch said in a singsong voice. 'Instant maidenhead.' One-Thumb hefted the leather-wrapped brick. 'One pinch, properly inserted, turns.you into a girl again.'

The eunuch rolled his eyes. 'An improvement over the old method.'

One-Thumb laughed along with him. 'I could spare a pinch or so, if you'd care for it.'

'Oh ... not on duty.' He leaned the sword against the wall and found a square of parchment in his money-belt. 'I could save it for my off time, though.' One Thumb gave him a pinch. He stared at it before folding it up. 'Black ... Caronne?'

'The best.'

'You have that much of it.' He didn't reach towards his weapon. One-Thumb's free hand rested on the pommel of his rapier. 'For sale, twenty grimales.'

'A man with no scruples would kill you for it.' Gap-toothed smile. 'I'm doubly safe with you, then.' The eunuch nodded and tucked away the krrf, then retrieved the broadsword. 'Safe with anyone not a stranger.' Everyone in the Maze knew of the curse that One-Thumb expensively maintained to protect his life: if he were killed, his murderer would never die, but live forever in helpless agony:

Burn as the stars burn; Burn on after they die. Never to the peace of ashes. Out of sight and succour From men or gods or ghost: To the ends of time, burn.

One-Thumb himself suspected that the spell would only be effective for as long as the sorcerer who cast it lived, but that was immaterial. The reputation of the sorcerer, Mizraith, as well as the severity of the spell, kept blades in sheaths and poison out of his food.

'I'll pass the message on. Many thanks.'

'Better mix it with snuff, you know. Very strong.' One-Thumb parted a velvet curtain and passed through the foyer, exchanging greetings with some of the women who lounged there in soft veils (the cut and colour of the veils advertised price, and in some cases, curious specialties), and stepped out into the waning light of the end of day.

The afternoon had been an interesting array of sensations for a man whose nose was as refined as it was large. First the banquet, with all its aromatic Twand delicacies, then the good rare wine with a delicate tang of half-poison, then the astringent krrf sting, the rich charnel smell of butchery, the musty sweat of the tunnel's rock walls, perfume and incense in the foyer, and now the familiar stink of the street. As he walked through the gate into the city proper, he could tell the wind was westering; the earthy smell from the animal pens had a slight advantage over the tanners' vats of rotting urine. He even sorted out the delicate cucumber fragrance of freshly butchered fish, like a whisper in a jabbering crowd; not many snouts had such powers of discrimination. As ever, he enjoyed the first few minutes within the city walls, before the reek stunned even his nose to dullness.
