The hand squeezed. Her chest heaved, but no air moved inside her neck. She struggled with the fingers, ripped at them with her nails, but they were made of iron, made of stone, tight as a hanged man's collar. She fought and twisted but he did not shift a hair's breadth. She fiddled with Mamun's ruined face, her fingers worked their way into his ripped cheek, tore at the dusty flesh inside but his eyes did not even blink. It had grown cold in the room.

'Say your prayers, child,' he whispered, broken teeth grinding, 'and hope that God is merciful.'

She was growing weaker now. Her lungs were bursting. She tore at him still, but each effort was less. Weaker and weaker. Her arms drooped, her legs dangled, her eyelids were heavy, heavy. All was terrible cold.

'Now,' he whispered, breath smoking. He brought her down, opening his mouth, his torn lips sliding back from his splintered teeth. 'Now.'

Her finger stabbed into his neck. Through his skin and into his dry flesh, up to the knuckle. It drove his head away. Her other hand wormed round his, prised it from her throat, bent his fingers backwards. She felt the bones in them snap, crunch, splinter as she dropped to the floor. White frost crept out across the black window-panes beside her, squeaked under her bare feet as she twisted Mamun round and rammed him against the wall, crushed his body into the splintering panels, the cracking plaster. Dust showered down from the force of it.

She drove her finger further into his throat, upwards, inwards. It was easy to do it. There was no end to her strength. It came from the other side of the divide. The Seed had changed her, as it had changed Tolomei, and there could be no going back.

Ferro smiled.

'Take my flesh, would you? You have had your last meal, Mamun.'

The tip of her finger slid out between his teeth, met her thumb and hooked him like a fish. With a jerk of her wrist she ripped the jaw-bone from his head and tossed it clattering away. His tongue lolled inside a ragged mass of dusty flesh.

'Say your prayers, Eater,' she hissed, 'and hope that God is merciful.' She clamped her palms around either side of his head. A long squeak came from his nose. His shattered hand pawed at her, uselessly. His skull bent, then flattened, then burst apart, splinters of bone flying. She let the body fall, dust sliding out across the floor, curling round her feet.

'Yes…'

She did not startle. She did not stare. She knew where the voice came from. Everywhere and nowhere.
