Houses oozed the white mucus of home-grubs. Some were completely coated in the thick stuff: it spread across roofs, linking different buildings into a lumpy, congealed totality. Lin could see in through windows and doors. The walls and floors that had been provided by human architects had been broken away in places, and the massive home-grubs allowed to burrow their blind way through the shell, oozing their phlegm-cement from their abdomens, their stubby little legs skittering as they ate their way through the ruined interiors of the buildings.

Occasionally Lin would see a live specimen taken from the farms by the river, going about its refitting of a building into the intricate twisting organic passageways preferred by most khepri tenants. The big, stupid beetles, larger than rhinos, responded to the tweaks and tugs of their keepers, blundering this way and that through the houses, recasting rooms in a quick-drying coating that softened edges and connected chambers, buildings and streets with what looked from the inside like giant worm-tracks.

Sometimes Lin would sit in one of Kinken’s tiny parks. She would be still among the slowly blossoming trees and watch her kind, all around her. She would stare high above the park, at the backs and sides of tall buildings. One time, she saw a young human girl lean out from a window high above, that was stuck almost at random at the top of a stained concrete wall at the back of the building. Lin saw the girl watching her khepri neighbours placidly, as her family’s washing fluttered and snapped in the brisk wind from a pole jutting beside her. A strange way of growing up, thought Lin, imagining the child surrounded by silent, insect-headed creatures, as strange as if Lin had been brought up among vodyanoi . . . but that thought led her uncomfortably in the direction of her own childhood.

Of course, her journey to these despised streets was a walk back through the city of her memory. She knew that. She was steeling herself to think back.

Kinken had been Lin’s first refuge. In this strange time of isolation, when she cheered the efforts of khepri crime-queens and walked as an outcast in all the quadrants of the city—except, perhaps, Salacus Fields, where outcasts ruled—she realized that her feelings for Kinken were more ambivalent than she had so far allowed.

There had been khepri in New Crobuzon for nearly seven hundred years, since the Fervent Mantis crossed the Swollen Ocean and reached Bered Kai Nev, the eastern continent, the khepri home. A few merchants and travellers had returned on a one-way mission of edification. For centuries, the stock of this tiny group sustained itself in the city, became natives. There had been no separate neighbourhoods, no home-grubs, no ghettos. There were not enough khepri. Not until the Tragic Crossing.
