"Oh, dear," said Tyrion. "Is there something grim and ugly behind it? Could it be that someone said something cruel about me once? I'll try not to weep. Tell me."

"Tyrion . . . "

Jaime is afraid. "Tell me," Tyrion said again.

His brother looked away. "Tysha," he said softly.

"Tysha?" His stomach tightened. "What of her?"

"She was no whore. I never bought her for you. That was a lie that Father commanded me to tell. Tysha was . . . she was what she seemed to be. A crofter's daughter, chance met on the road."

Tyrion could hear the faint sound of his own breath whistling hollowly through the scar of his nose. Jaime could not meet his eyes. Tysha. He tried to remember what she had looked like. A girl, she was only a girl, no older than Sansa. "My wife," he croaked. "She wed me."

"For your gold, Father said. She was lowborn, you were a Lannister of Casterly Rock. All she wanted was the gold, which made her no different from a whore, so . . . so it would not be a lie, not truly, and . . . he said that you required a sharp lesson. That you would learn from it, and thank me later . . . "

"Thank you?" Tyrion's voice was choked. "He gave her to his guards. A barracks full of guards. He made me . . . watch." Aye, and more than watch. I took her too . . . my wife . . .

"I never knew he would do that. You must believe me."

"Oh, must I?" Tyrion snarled. "Why should I believe you about anything, ever? She was my wife!"

"Tyrion - "

He hit him. It was a slap, backhanded, but he put all his strength into it, all his fear, all his rage, all his pain. Jaime was squatting, unbalanced. The blow sent him tumbling backward to the floor. "I . . . I suppose I earned that."

"Oh, you've earned more than that, Jaime. You and my sweet sister and our loving father, yes, I can't begin to tell you what you've earned. But you'll have it, that I swear to you. A Lannister always pays his debts." Tyrion waddled away, almost stumbling over the turnkey again in his haste. Before he had gone a dozen yards, he bumped up against an iron gate that closed the passage. Oh, gods. It was all he could do not to scream.

Jaime came up behind him. "I have the gaoler's keys."

"Then use them." Tyrion stepped aside.

Jaime unlocked the gate, pushed it open, and stepped through. He looked back over his shoulder. "Are you coming?"

"Not with you." Tyrion stepped through. "Give me the keys and go. I will find Varys on my own." He cocked his head and stared up at his brother with his mismatched eyes. "Jaime, can you flght left-handed?"

"Rather less well than you," Jaime said bitterly.

"Good. Then we will be well matched if we should ever meet again. The cripple and the dwarf."

Jaime handed him the ring of keys. "I gave you the truth. You owe me the same. Did you do it? Did you kill him?"

The question was another knife, twisting in his guts. "Are you sure you want to know?" asked Tyrion. "Joffrey would have been a worse king than Aerys ever was. He stole his father's dagger and gave it to a footpad to slit the throat of Brandon Stark, did you know that?"

"I . . . I thought he might have."

"Well, a son takes after his father. Joff would have killed me as well, once he came into his power. For the crime of being short and ugly, of which I am so conspicuously guilty."

"You have not answered my question."

"You poor stupid blind crippled fool. Must I spell every little thing out for you? Very well. Cersei is a lying whore, she's been f**king Lancel and Osmund Kettleblack and probably Moon Boy for all I know. And I am the monster they all say I am. Yes, I killed your vile son." He made himself grin. It must have been a hideous sight to see, there in the torchlit gloom.

Jaime turned without a word and walked away.

Tyrion watched him go, striding on his long strong legs, and part of him wanted to call out, to tell him that it wasn't true, to beg for his forgiveness. But then he thought of Tysha, and he held his silence. He listened to the receding footsteps until he could hear them no longer, then waddled off to look for Varys.

The eunuch was lurking in the dark of a twisting turnpike stair, garbed in a moth-eaten brown robe with a hood that hid the paleness of his face. "You were so long, I feared that something had gone amiss," he said when he saw Tyrion.

"Oh, no," Tyrion assured him, in poisonous tones. "What could possibly have gone amiss?" He twisted his head back to stare up. "I sent for you during my trial."

"I could not come. The queen had me watched, night and day. I dared not help you."

"You're helping me now."

"Am I? Ah." Varys giggled. It seemed strangely out of place in this place of cold stone and echoing darkness. "Your brother can be most persuasive."

"Varys, you are as cold and slimy as a slug, has anyone ever told you? You did your best to kill me. Perhaps I ought to return the favor."

The eunuch sighed. "The faithful dog is kicked, and no matter how the spider weaves, he is never loved. But if you slay me here, I fear for you, my lord. You may never find your way back to daylight." His eyes glittered in the shifting torchlight, dark and wet. "These tunnels are full of traps for the unwary."

Tyrion snorted. "Unwary? I'm the wariest man who ever lived, you helped see to that." He rubbed at his nose. "So tell me, wizard, where is my innocent maiden wife?"

"I have found no trace of Lady Sansa in King's Landing sad to say. Nor of Ser Dontos Hollard, who by rights should have turned up somewhere drunk by now. They were seen together on the serpentine steps the night she vanished. After that, nothing. There was much confusion that night. My little birds are silent." Varys gave a gentle tug at the dwarf's sleeve and pulled him into the stair. "My lord, we must away. Your path is down."

That's no lie, at least. Tyrion waddled along in the eunuch's wake, his heels scraping against the rough stone as they descended. It was very cold within the stairwell, a damp bone-chilling cold that set him to shivering at once. "What part of the dungeons are these?" he asked.

"Maegor the Cruel decreed four levels of dungeons for his castle," Varys replied. "On the upper level, there are large cells where common criminals may be confined together. They have narrow windows set high in the walls. The second level has the smaller cells where highborn captives are held. They have no windows, but torches in the halls cast light through the bars. On the third level the cells are smaller and the doors are wood. The black cells, men call them. That was where you were kept, and Eddard Stark before you. But there is a level lower still. Once a man is taken down to the fourth level, he never sees the sun again, nor hears a human voice, nor breathes a breath free of agonizing pain. Maegor had the cells on the fourth level built for torment." They had reached the bottom of the steps. An unlighted door opened before them. "This is the fourth level. Give me your hand, my lord. It is safer to walk in darkness here. There are things you would not wish to see."

Tyrion hung back a moment. Varys had already betrayed him once. Who knew what game the eunuch was playing? And what better place to murder a man than down in the darkness, in a place that no one knew existed? His body might never be found.

On the other hand, what choice did he have? To go back up the steps and walk out the main gate? No, that would not serve.

Jaime would not be afraid, he thought, before he remembered what Jaime had done to him. He took the eunuch by the hand and let himself be led through the black, following the soft scrape of leather on stone. Varys walked quickly, from time to time whispering, "Careful, there are three steps ahead," or, "The tunnel slopes downward here, my lord." I arrived here a King's Hand, riding through the gates at the head of my own sworn men, Tyrion reflected, and I leave like a rat scuttling through the dark, holding hands with a spider.

A light appeared ahead of them, too dim to be daylight, and grew as they hurried toward it. After a while he could see it was an arched doorway, closed off by another iron gate. Varys produced a key. They stepped through into a small round chamber. Five other doors opened off the room, each barred in iron. There was an opening in the ceiling as well, and a series of rungs set in the wall below, leading upward. An ornate brazier stood to one side, fashioned in the shape of a dragon's head. The coals in the beast's yawning mouth had burnt down to embers, but they still glowed with a sullen orange light. Dim as it was, the light was welcome after the blackness of the tunnel.

The juncture was otherwise empty, but on the floor was a mosaic of a three-headed dragon wrought in red and black tiles. Something niggled at Tyrion for a moment. Then it came to him. This is the place Shae told me of, when Varys first led her to my bed. "We are below the Tower of the Hand."

"Yes." Frozen hinges screamed in protest as Varys pulled open a long-closed door. Flakes of rust drifted to the floor. "This will take us out to the river."

Tyrion walked slowly to the ladder, ran his hand across the lowest rung. "This will take me up to my bedchamber."

"Your lord father's bedchamber now."

He looked up the shaft. "How far must I climb?"

"My lord, you are too weak for such follies, and there is besides no time. We must go."

"I have business above. How far?"

"Two hundred and thirty rungs, but whatever you intend - "

"Two hundred and thirty rungs, and then?"

"The tunnel to the left, but hear me - "

"How far along to the bedchamber?" Tyrion lifted a foot to the lowest rung of the ladder.

"No more than sixty feet. Keep one hand on the wall as you go. You will feel the doors. The bedchamber is the third." He sighed. "This is folly, my lord. Your brother has given you your life back. Would you cast it away, and mine with it?"

"Varys, the only thing I value less than my life just now is yours. Wait for me here." He turned his back on the eunuch and began to climb, counting silently as he went.

Rung by rung, he ascended into darkness. At first he could see the dim outline of each rung as he grasped it, and the rough grey texture of the stone behind, but as he climbed the black grew thicker. Thirteen fourteen fifteen sixteen. By thirty, his arms trembled with the strain of pulling. He paused a moment to catch his breath and glanced down. A circle of faint light shone far below, half obscured by his own feet. Tyrion resumed his ascent. Thirty-nine forty forty-one. By fifty, his legs burned. The ladder was endless, numbing. Sixty-eight sixty-nine seventy. By eighty, his back was a dull agony. Yet still he climbed. He could not have said why. One thirteen one fourteen one fifteen.

At two hundred and thirty, the shaft was black as pitch, but he could feel the warm air flowing from the tunnel to his left, like the breath of some great beast. He poked about awkwardly with a foot and edged off the ladder. The tunnel was even more cramped than the shaft. Any man of normal size would have had to crawl on hands and knees, but Tyrion was short enough to walk upright. At last, a place made for dwarfs. His boots scuffed softly against the stone. He walked slowly, counting steps, feeling for gaps in the walls. Soon he began to hear voices, muffled and indistinct at first, then clearer. He listened more closely. Two of his father's guardsmen were joking about the Imp's whore, saying how sweet it would be to f**k her, and how bad she must want a real c**k in place of the dwarf's stunted little thing. "Most like it's got a crook in it," said Lum. That led him into a discussion of how Tyrion would die on the morrow. "He'll weep like a woman and beg for mercy, you'll see," Lum insisted. Lester figured he'd face the axe brave as a lion, being a Lannister, and he was willing to bet his new boots on it. "Ah, shit in your boots," said Lum, "you know they'd never fit these feet o' mine. Tell you what, if I win you can scour my bloody mail for a fortnight."
