others, one receives in return." She flashed him a sharp-toothed grin, and said, "Get down, Aleran."
Tavi dropped to one knee just as Kitai raised the hook and whirled it in a circle, letting out the line and gathering speed. It didn't take her long. Four circles, five, and she let out a hiss and flung the hook and the line across the distance to the roof. Metal clinked faintly on stone.
Kitai began drawing the cord in, very slowly and carefully. The rope suddenly tightened, and she continued to lean back, steadily increasing the pressure. "Here," she said. "In the pouch. There is a metal spike there, a hammer."
Tavi slipped his hand into the pouch and found them. The spike had an open ring set into the butt end, and Tavi grasped its use at once. He knelt with the spike and the hammer. He took off his cloak and folded it a few times, then drove the spike carefully into the stone of the aqueduct, the cloth muffling the sound of the hammerblows. Tavi drove it in at an angle opposite the pull of the rope, and when he was finished he glanced up to find Kitai looking down at the spike with approval.
She passed him the end of the Marat rope, and Tavi threaded it through the eye on the end of the spike. He took in the last few feet very slowly, with Kitai careful to keep the pressure against the grappling hook, until he was able to lean his full weight against it, holding it in place.
Kitai nodded sharply and her hands flew through another knot, one Tavi was not familiar with. She tied off the rope, using the knot to draw it tight and to tighten it even more before she released it, leaned back, and nodded to Tavi.
The boy released the rope slowly. It made a faint, strong thrumming sound, and stretched out between the aqueduct and the Tower, glistening like spider silk in the ambient radiance of the city's thousands upon thousands of furylamps. "So," he said. "We cross on the rope to avoid the earth and wood furies in the lawn. Right?"
"Yes," Kitai said.
"That's going to leave wind furies on watch around the roof," he said. "And it looks like there might be a gargoyle at either end. See, those lumps there'?"
Kitai frowned. "What is this, gargoyle?"
"It's an earth fury," Tavi explained. "A statue that is able to perceive and to move. They're not very fast, but they are strong."
"They will try to harm us?"
"Probably," Tavi said quietly. "They'll respond to movement on the roof."
"Then we must not touch foot to the roof, yes?"
Tavi nodded. "It might work. But I don't see how else we're going to get inside but the door on the roof. There are guards at all the lower doors."
"Give me your cloak," Kitai said.
Tavi passed it over to her. "What are you doing?"
"Seeing to the wind furies," she said. She slipped her cloak off and thrust them both into the cold current of water running through the aqueduct, soaking them. Then she opened another pouch and drew out a heavy ??wooden canister, which proved to be full of salt. She started spreading it heavily over the damp cloaks.
Tavi watched that, frowning. "I know salt is painful to wind furies," he said. "But does that actually work?"
Kitai paused and gave him an even look. Then she glanced down at her clothing and jewelry and back up to Tavi.
He lifted his hands. "All right, all right. If you say so."
She rose a moment later and tossed him the cloak. Tavi caught it, and drew the wet, sodden mass on. Kitai did the same. "Are you ready, Aleran?"
"Ready for what?" Tavi asked. "I'm still not sure how we're going to get in without touching down on the roof."
Kitai nodded at the narrow windows on the topmost floor. "I will go in through there. Wait until I am all the way across before you start. The rope is not designed to hold two."
"Better let me go first," Tavi said. "I'm heavier. If it's going to collapse, it will be for me."
Kitai frowned at him, but nodded. She gestured to the rope, and said, "Go on. Leave me space to work when I get there."
Tavi nodded, then turned to look at the slender rope stretching across to the Grey Tower. He swallowed and felt his fingers trembling. But he forced himself to move, sliding over to the rope and taking it in his hands.
