Kill him.

The thought was as clear as if someone behind him had spoken it No, thought Nafai. I can't do that. I can't kill a man.

Why do you think I brought you here? He's a killer. The law decrees his death.

The law decreed my death for seeing the Lake of Women, Nafai answered silently. Yet I was shown mercy.

I brought you to the lake, Nafai. As I brought you here. To do what must be done. You'll never get the Index while he's alive.

I cant kill a man. A helpless man like this-it would be murder.

It would be simple justice.

Not if it came from my hand. I hate him too much. I want him dead. For the humiliation of my family. For stealing my father's title. For taking our fortune. For the beating I got at my brother's hands. For the soldiers and the tokhocks, for the way he has blotted the light of hope out of my city. For the way he turned Rashgallivak, that good man, into a weak and foolish tool. For all those things I want him to die, I want to crush him under my foot. If I kill him now I'm a coward and an assassin, not a justicer.

He tried to kill you. His assassins had you marked for death.

I know it. So it would be private vengeance if I killed him now.

Think of what you're doing, Nafai. Think.

I'm not going to be a murderer.

That's right. You're going to save lives. There's only one hope of saving this world from the slaughter that destroyed Earth forty million years ago, and leaving this man alive will obliterate that hope. Should the billion souls of the planet Harmony all die, so that you can keep your hands dean? I tell you that this is not murder, not assassination, but justice. I have tried him and found him guilty. He ordered the death of Roptat, and your death, and your brothers' death, and the death of your father. He plots a war that will kill thousands and bring this city under subjugation. You aren't sparing him out of mercy, Nafai, because only his death will be merciful to the city and the people that you love, only his death will show mercy to the world. You're sparing him out of pure vanity. So that you can look at your hands and find them unstained with blood. I tell you that if you don't kill this man, the blood of millions will be on your head.

No!

Nafai's cry was all the more anguished for being silent, for being contained inside his mind.

The voice inside his head did not relent: The Index opens the deepest library in the world, Nafai. With it, all things are possible to my servants. Without it, I have no dearer voice than the one you hear now, constantly changed and distorted by your own fears and hopes and expectations. Without the Index, I can't help you and you can't help me. My powers will continue to fade, and my law will dwindle among the people, until at last the fires come again, and another world is laid waste. The Index, Nafai. Take from this man what the law requires, and then go and get the Index.

Nafai reached down and took the charged-wire blade that was hooked to Gaballufix's belt.

I don't know how to kill a man with this. It doesn't stab. I can't stab the heart with this.

His head. Take off his head.

I can't. I can't, I can't, I can't.

But Nafai was wrong. He could He took Gaballufix by the hair, and stretched out his neck. Gaballufix stirred-was he waking up? Nafai almost let go of his hair then, but Gaballufix quickly dropped back into unconsciousness. Nafai switched on the blade and then laid" it lightly against the throat. The blade hummed. A line of blood appeared. Nafai pressed harder, and the line became an open wound, with blood spouting over the blade, sizzling loudly. Too late to stop now, too late. He pressed harder, harder. The blade bit deeper. It resisted at the bone, but Nafai twisted the head away and opened a gap between the vertebrae, and now the blade cut through easily, and the head came free.

Nafai's pants and shirt were covered with blood, as were his hands and face, spattered with it, dripping with it. I have killed a man, and this is his head that I'm holding in my hands. What am I now? Who am I now? How am I better than the man who lies here, torn apart by my hands?

The Index.

He couldn't bear to wear his blood-soaked clothes. Almost in a panic to be rid of them, he tore them off, then wiped his face and hands on the unbloodied back of his shirt. These were the clothes that Luet handed to me when I climbed back into the boat in the beautiful, peaceful place, and now see what I've done with them.

Now, kneeling beside the body, his own clothes cast down into the blood, he realized that because of the downhill slope of the street and the fact that the blood mostly poured upward out of the neck, away from the body, Gaballufix's own clothing was unstained with blood. Vomit and urine, yes, but not blood. Nafai had to wear something. The costume wouldn't be enough- underneath it he'd be cold and barefoot.

When he thought of putting on Gaballufix's clothing, it was abhorrent to him, yes, but he also knew that he had to do it. He dragged the body up away from the blood a little, then undressed it carefully, keeping the blood off. He almost gagged as he pulled the cold wet trousers on, but then he thought contemptuously that a man who could kill the way he had just killed should hardly feel squeamish about wearing another man's piss on his legs. The same with the stench of stomach acid in the shirt and the body armor that Gaballufix had been wearing underneath. Nothing is too horrible for me to do it now, thought Nafai. I'm already lost.

The only thing he could not bring himself to do was put the blade at his waist, the way Gaballufix had done. Instead he wiped his fingerprints from the handle and tossed it down near where the head was lying. Then he laughed. There are my clothes, which countless witnesses saw me wearing today. Why should I have tried to conceal myself, if I'm leaving those behind?

And I am leaving those behind, thought Nafai. Like my own dead body I'm leaving those. The costume of a child. I'm wearing a man's clothes now. And not just any man. The most vile, monstrous man I know. They fit me.

He pulled the cloak of the soldier costume over his head. He felt no different, but he assumed that the look was there. He stepped away from the body. He could not think of where to go now. He could not think of anything,

He turned back to the body. He had left something behind, he knew that. But all that was left was his old clothing, and the blade. So he picked up the blade again after all, wiped the blood from it with his old clothes, and put it on his belt.

Now he could go on. To Gaballufix's house, of course. He knew that now, very clearly. He could think very clearly now. The trousers froze on his legs, and chafed. The body armor was heavy. It was awkward walking with the charged-wire blade. This is how it felt to be Gaballufix, thought Nafai. Tonight I am Gaballufix.

I have to hurry. Before the body is found.

No. The Oversoul will keep them from noticing the body, for a while at least. Until they are so many people out in the morning that the Oversoul can't influence them all at once. So I do have time.

He came up Fountain Street, but then thought better of it. Instead he walked over to Long Street and came up to Gaballufix's house from behind. In the alley he found the door that he had seen Elemak use, so many-so few-days before. Would it be locked?

It was. What now? Inside there would be someone waiting. Keeping guard. How could he, in the guise of a common soldier, demand entrance at this hour? What if they made him switch off the costume once he got inside? They'd recognize him at once. Worse, they'd recognize Gaballufix's clothing and they'd know that there was only one way he could come in wearing their master's clothes.

No, two ways.
