This is my favorite part in the "Storm of Swords" by George R.R. Martin.
summary: The Edmure Tully and Roselyn Frey are to wed to seal the alliance between Starks and Freys, but what was supposed to be a grand wedding turned out to be a very well plotted massaccre of the family. Point of view is with Catelyn, the mother of the King Stark.
Dacey Mormont, who seemed to be the only woman left in the hall besides Catelyn, stepped up behind Edwyn Frey, and touched him lightly on the arm as she said something in his ear. Edwyn wrenched himself away from her with unseemly violence.
"No," he said, too loudly. "I'm done with dancing for the nonce."
Dacey paled and turned away. Catelyn got slowly to her feet. What just happened there? Doubt gripped her heart, where an instant before had been only weariness. It is nothing, she tried to tell herself, you are seeing grumkins in the woodpile, you are become an old silly woman sick with grief and fear. But something must have shown on her face. Even Ser Wendel Manderly took note.
"Is something amiss?" he asked, the leg of lamb in his hands.
She did not answer him. Instead she went after Edwyn Frey. The players in the gallery had finally gotten both king and queen down to their name-day suits. With scarcely a moment's respite, they began to play a very different sort of song. No one sang the words, but Catelyn knew "The Rains of Castamere" when she heard it. Edwyn was hurrying toward a door. She hurried faster, driven by the music. Six quick strides and she caught him. And who are you, the proud lord said, that I must bow so low? She grabbed Edwyn by the arm to turn him and went cold all over when she felt the iron rings beneath his silken sleeve. Catelyn slapped him so hard she broke his lip. Olyvar, she thought, and Perwyn, Alesander, all absent. And Roslin wept ...
Edwyn Frey shoved her aside. The music drowned all other sound, echoing off the walls as if the stones themselves were playing. Robb gave Edwyn an angry look and moved to block his way ... and staggered suddenly as a quarrel sprouted from his side, just beneath the shoulder. if he screamed then, the sound was swallowed by the pipes and horns and fiddles. Catelyn saw a second bolt pierce his leg, saw him fall. Up in the gallery, half the musicians had crossbows in their hands instead of drums or lutes. She ran toward her son, until something punched in the small of the back and the hard stone floor came up to slap her.
"Robb!" she screamed.
She saw Smalljon Umber wrestle a table off its trestles. Crossbow bolts thudded into the wood, one two three, as he flung it down on top of his king. Robin Flint was ringed by Freys, their daggers rising and falling. Ser Wendel Manderly rose ponderously to his feet, holding his leg of lamb. A quarrel went in his open mouth and came out the back of his neck. Ser Wendel crashed forward, knocking the table off its trestles and sending cups, flagons, trenchers, platters, turnips, beets, and wine bouncing, spilling, and sliding across the floor.
Catelyn's back was on fire. I have to reach him. The Smalljon bludgeoned Ser Raymund Frey across the face with a leg of mutton. But when he reached for his swordbelt a crossbow bolt drove him to his knees. In a coat of gold or a coat of red, a lion still has claws. She saw Lucas Blackwood cut down by Ser Hosteen Frey. One of the Vances was hamstrung by Black Walder as he was wrestling with Ser Harys Haigh. And mine are long and sharp, my lord, as long and sharp as yours. The crossbows took Donnel Locke, Owen Norrey, and half a dozen more. Young Ser Benfrey had seized Dacey Mormont by the arm, but Catelyn saw her grab up a flagon of wine with her other hand, smash it full in his face, and run for the door. It flew open before she reached it. Ser Ryman Frey pushed into the hall, clad in steel from helm to heel. A dozen Frey men-atarms packed the door behind him. They were armed with heavy longaxes.
"Mercy!" Catelyn cried, but horns and drums and the clash of steel smothered her plea. Ser Ryman buried the head of his axe in Dacey's stomach. By then men were pouring in the other doors as well, mailed men in shaggy fur cloaks with steel in their hands. Northmen! She took them for rescue for half a heartbeat, till one of them struck the Smalljon's head off with two huge blows of his axe. Hope blew out like a candle in a storm. in the midst of slaughter, the Lord of the Crossing sat on his carved oaken throne, watching greedily.
There was a dagger on the floor a few feet away. Perhaps it had skittered there when the Smalljon knocked the table off its trestles, or perhaps it had fallen from the hand of some dying man. Catelyn crawled toward it. Her limbs were leaden, and the taste of blood was in her mouth. I will kill Walder Frey, she told herself. jinglebell was closer to the knife, hiding under a table, but he only cringed away as she snatched up the blade. I Mll kill the old man, I can do that much at least.
Then the tabletop that the Smalljon had flung over Robb shifted , and her son struggled to his knees. He had an arrow in his side, a second in his leg, a third through his chest. Lord Walder raised a hand, and the music stopped, all but one drum. Catelyn heard the crash of distant battle, and closer the wild howling of a wolf. Grey Wind, she remembered too late.
"Heh," Lord Walder cackled at Robb, "the King in the North arises. Seems we killed some of your men, Your Grace. Oh, but I'll make you an apology, that will mend them all again, heh.-
Catelyn grabbed a handful of jinglebell Frey's long grey hair and dragged him out of his hiding place.
"Lord Walder!" she shouted.
"LORD WALDER!" The drum beat slow and sonorous, doom boom doom.
"Enough," said Catelyn. "Enough, I say. You have repaid betrayal with betrayal, let it end." When she pressed her dagger to jinglebell's throat, the memory of Bran's sickroom came back to her, with the feel of steel at her own throat. The drum went boom doom boom doom boom doom.
"Please," she said. "He is my son. My first son, and my last. Let him go. Let him go and I swear we will forget this ... forget all you've done here. I swear it by the old gods and new, we ... we will take no vengeance. . . "
Lord Walder peered at her in mistrust. "Only a fool would believe such blather. D'you take me for a fool, my lady?"
"I take you for a father. Keep me for a hostage, Edmure as well if you haven't killed him. But let Robb go."
"No. " Robb's voice was whisper faint. "Mother, no . . .
"Yes. Robb, get up. Get up and walk out, please, please. Save yourself ... if not for me, for Jeyne."
"Jeyne?" Robb grabbed the edge of the table and forced himself to stand.
"Mother," he said, "Grey Wind..."
"Go to him. Now. Robb, walk out of here."
Lord Walder snorted. "And why would I let him do that?"
She pressed the blade deeper into jinglebell's throat. The lackwit rolled his eyes at her in mute appeal. A foul stench assailed her nose, but she paid it no more mind than she did the sullen ceaseless pounding of that drum, boom doom boom doom boom doom. Ser Ryman and Black Walder were circling round her
back, but Catelyn did not care. They could do as they wished with her; imprison her, rape her, kill her, it made no matter. She had lived too long, and Ned was waiting. It was Robb she feared for.
"On my honor as a Tully," she told Lord Walder, "on my honor as a Stark, I will trade your boy's life for Robb's. A son for a son." Her hand shook so badly she was ringing Jinglebell's head. Boom, the drum sounded, boom doom boom doom. The old man's lips went in and out.
The knife trembled in Catelyn's hand, slippery with sweat.
"A son for a son, heh," he repeated. "But that's a grandson ... and he never was much use."
A man in dark armor and a pale pink cloak spotted with blood stepped up to Robb.
"Jaime Lannister sends his regards." He thrust his longsword through her son's heart, and twisted.
Robb had broken his word, but Catelyn kept hers. She tugged hard on Aegon's hair and sawed at his neck until the blade grated on bone. Blood ran hot over her fingers. His little bells were ringing, ringing, ringing, and the drum went boom doom boom.
Finally someone took the knife away from her. The tears burned like vinegar as they ran down her cheeks. Ten flerce ravens were raking her face with sharp talons and tearing off strips of flesh, leaving deep furrows that ran red with blood. She could taste it on her lips.
It hurts so much, she thought. Our children, Ned, all our sweet babes. Rickon, Bran, Arya, Sansa, Robb ... Robb ... please, Ned, please, make it stop, make it stop hurting ... The white tears and the red ones ran together until her face was torn and tattered, the face that Ned had loved. Catelyn Stark raised her hands and watched the blood run down her long fingers, over her wrists, beneath the sleeves of her gown. Slow red worms crawled along her arms and under her clothes. It tickles. That made her laugh until she screamed. "Mad," someone said, "she's lost her wits," and someone else said, "Make an end," and a hand grabbed her scalp just as she'd done with Jinglebell, and she thought, No, don't, don't cut my hair, Ned loves my hair. Then the steel was at her throat, and its bite was red and cold.
