““The Red Keep was full of cats: lazy old cats dozing in the sun, cold-eyed mousers twitching their tails, quick little kittens with claws like needles, ladies’ cats all combed and trusting, ragged shadows prowling the midden heaps. One by one Arya had chased them down and snatched them up and brought them proudly to Syrio Forel … all but this one, this one-eared black devil of a tomcat. “That’s the real king of this castle right there,” one of the gold cloaks had told her. “Older than sin and twice as mean. One time, the king was feasting the queen’s father, and that black bastard hopped up on the table and snatched a roast quail right out of Lord Tywin’s fingers. Robert laughed so hard he like to burst. You stay away from that one, child.” He had run her halfway across the castle; twice around the Tower of the Hand, across the inner bailey, through the stables, down the serpentine steps, past the small kitchen and the pig yard and the barracks of the gold cloaks, along the base of the river wall and up more steps and back and forth over Traitor’s Walk, and then down again and through a gate and around a well and in and out of strange buildings until Arya didn’t know where she was. Now at last she had him. High walls pressed close on either side, and ahead was a blank windowless mass of stone. Quiet as a shadow, she repeated, sliding forward, light as a feather. When she was three steps away from him, the tomcat bolted. Left, then right, he went; and right, then left, went Arya, cutting off his escape. He hissed again and tried to dart between her legs. Quick as a snake, she thought.””
