The Remade breached the low rise of bricks without hesitation, only faltering when they saw the Weaver’s huge and skulking form scampering to and fro across the bricks, three figures jouncing like dolls on its back.

Motley’s troops stepped back towards the edge slowly, rain varnishing their impassive steel faces. Their heavy feet crushed the remnants of the engines that still lay split across the roof.

As they watched, the Weaver reached down and grasped hold of a quailing militiaman, who wailed in terror as he was dragged up by his head. The man flailed, but the Weaver pushed his arms away and cuddled him like a baby.

. . . OFF AND ON TO GO HUNTING WE WILL TAKE OUR LEAVE . . . whispered the Weaver to all present. It walked sideways off the edge of the roof, seemingly unencumbered, and disappeared.

For two or three seconds, only the rain sounded fitful and depressing on the roof. Then Half-a-Prayer let off a last volley of shots from above, sending the assembled men and Remade scattering. When they emerged carefully, there were no more attacks. Jack Half-a-Prayer had gone.

The Weaver and its companions had left no trail, and no trace.

The slake-moth tore through currents of air. It was frantic and afraid.

It sounded every so often, letting out a cry in a variety of sonic registers, but it was unanswered. It was miserable and confused.

And yet beneath it all, its infernal hunger was growing again. It was not free of its appetite.

Below it the Canker flowed through the city, its barges and pleasure boats little grubs of dirty light on the blackness. The slake-moth slowed and spiralled.

A line of filthy smoke was drawn slowly across the face of New Crobuzon, marking it like a stub of pencil, as a late train went east on the Dexter Line, through Gidd and Barguest Bridge, on over the water towards Lud Fallow and Sedim Junction.

The moth swept on over Ludmead, ducking low above the roofs of the university faculty, alighting briefly on the roof of the Magpie Cathedral in Saltbur, flitting away in a pang of hunger and lonely fear. It could not rest. It could not channel its rapacity to feed.

As it flew, the slake-moth recognized the configuration of light and darkness below it. It felt a sudden pull.

Behind the railway lines, rising from the shabby and decrepit architecture of Bonetown, the Ribs rose out into the night air in a colossal sweep and curve of ivory. They made memories eddy in the slake-moth’s head. It recalled the dubious influence of those old bones that had made Bonetown a fearful place, somewhere to be escaped, where air currents were unpredictable and noxious tides could pollute the æther. Distant images of days clamped still, being milked lasciviously, its glands sucked clean, a hazy sense of a suckling grub at its teat, but nothing being there . . . memories caught it up.
