Whatever names Harren the Black had meant to give his towers were long forgotten. They were called the Tower of Dread, the Widow’s Tower, the Wailing Tower, the Tower of Ghosts, and Kingspyre Tower. Arya slept in a shallow niche in the cavernous vaults beneath the Wailing Tower, on a bed of straw. She had water to wash in whenever she liked, a chunk of soap. The work was hard, but no harder than walking miles every day. Weasel did not need to find worms and bugs to eat, as Arry had; there was bread every day, and barley stews with bits of carrot and turnip, and once a fortnight even a bite of meat.  Hot Pie ate even better; he was where he belonged, in the kitchens, a round stone building with a domed roof that was a world unto itself. Arya took her meals at a trestle table in the undercroft with Weese and his other charges, but sometimes she would be chosen to help fetch their food, and she and Hot Pie could steal a moment to talk. He could never remember that she was now Weasel and kept calling her Arry, even though he knew she was a girl. Once he tried to slip her a hot apple tart, but he made such a clumsy job of it that two of the cooks saw. They took the tart away and beat him with a big wooden spoon.  Gendry had been sent to the forge; Arya seldom saw him. As for those she served with, she did not even want to know their names. That only made it hurt worse when they died. Most of them were older than she was and content to let her alone.  Harrenhal was vast, much of it far gone in decay. Lady Whent had held the castle as bannerman to House Tully, but she’d used only the lower thirds of two of the five towers, and let the rest go to ruin. Now she was fled, and the small household she’d left could not begin to tend the needs of all the knights, lords, and highborn prisoners Lord Tywin had brought, so the Lannisters must forage for servants as well as for plunder and provender. The talk was that Lord Tywin planned to restore Harrenhal to glory, and make it his new seat once the war was done.  Weese used Arya to run messages, draw water, and fetch food, and sometimes to serve at table in the Barracks Hall above the armory, where the men-at-arms took their meals. But most of her work was cleaning. The ground floor of the Wailing Tower was given over to storerooms and granaries, and two floors above housed part of the garrison, but the upper stories had not been occupied for eighty years. Now Lord Tywin had commanded that they be made fit for habitation again. There were floors to be scrubbed, grime to be washed off windows, broken chairs and rotted beds to be carried off. The topmost story was infested with nests of the huge black bats that House Whent had used for its sigil, and there were rats in the cellars as well... and ghosts, some said, the spirits of Harren the Black and his sons.  Arya thought that was stupid. Harren and his sons had died in Kingspyre Tower, that was why it had that name, so why should they cross the yard to haunt her? The Wailing Tower only wailed when the wind blew from the north, and that was just the sound the air made blowing through the cracks in the stones where they had fissured from the heat. if there were ghosts in Harrenhal, they never troubled her. It was the living men she feared, Weese and Ser Gregor Clegane and Lord Tywin Lannister himself, who kept his apartments in Kingspyre Tower, still  the tallest and mightiest of all, though lopsided beneath the weight of the slagged stone that made it look like some giant half-melted black candle.  She wondered what Lord Tywin would do if she marched up to him and confessed to being Arya Stark, but she knew she’d never get near enough to talk to him, and anyhow he’d never believe her if she did, and afterward Weese would beat her bloody.  In his own small strutting way, Weese was nearly as scary as Ser Gregor. The Mountain swatted men like flies, but most of the time he did not even seem to know the fly was there. Weese always knew you were there, and what you were doing, and sometimes what you were thinking. He would hit at the slightest provocation, and he had a dog who was near as bad as he was, an ugly spotted bitch that smelled worse than any dog Arya had ever known. Once she saw him set the dog on a latrine boy who’d annoyed him. She tore a big chunk out of the boy’s calf while Weese laughed.  It took him only three days to earn the place of honor in her nightly prayers. “Weese,” she would whisper, first of all. “Dunsen, Chiswyck, Polliver, Raff the Sweetling. The Tickler and the Hound. Ser Gregor, Ser Amory, Ser Ilyn, Ser Meryn, King Joffrey, Queen Cersei.” If she let herself forget even one of them, how would she ever find him again to kill him?  On the road Arya had felt like a sheep, but Harrenbal turned her into a mouse. She was grey as a mouse in her scratchy wool shift, and like a mouse she kept to the crannies and crevices and dark holes of the castle, scurrying out of the way of the mighty. Sometimes she thought they were all mice within those thick walls, even the knights and the great lords. The size of the castle made even Gregor Clegane seem small. Harrenhal covered thrice as much ground as Winterfell, and its buildings were so much larger they could scarcely be compared. Its stables housed a thousand horses, its godswood covered twenty acres, its kitchens were as large as Winterfell’s Great Hall, and its own great hall, grandly named the Hall of a Hundred Hearths even though it only had thirty and some (Arya had tried to count them, twice, but she came up with thirty-three once and thirty-five the other time) was so cavernous that Lord Tywin could have feasted his entire host, though he never did. Walls, doors, halls, steps, everything was built to an inhuman scale that made Arya remember the stories Old Nan used to tell of the giants who lived beyond the Wall.  And as lords and ladies never notice the little grey mice under their feet, Arya heard all sorts of secrets just by keeping her ears open as she went about her duties. Pretty Pia from the buttery was a slut who was working her way through every knight in the castle. The wife of the gaoler was with child, but the real father was either Ser Alyn Stackspear or a singer called Whitesmile Wat. Lord Lefford made mock of ghosts at table, but always kept a candle burning by his bed. Ser Dunaver’s squire Jodge could not hold his water when he slept. The cooks despised Ser Harys Swyft and spit in all his food. Once she even overheard Maester Tothmure’s serving girl confiding to her brother about some message that said Joffrey was a bastard and not the rightful king at all. “Lord Tywin told him to burn the letter and never speak such filth again,” the girl whispered.   King Robert’s brothers Stannis and Renly had joined the fighting, she heard. “And both of them kings now,” Weese said. “Realm’s got more kings than a castle’s got rats.” Even Lannister men questioned how long Joffrey would hold the Iron Throne. “The lad’s got no army but them gold c............
