He walks the city at the behest of the grub, the oddity in him that will not be still. He is tugged by it; he feels it seeing through him. It’s a strong goodness in me, he thinks without arrogance, but it’s an intruder. I don’t feel it as my own. Does that make me good? Does that make me better? Does it make me wicked?

Judah thinks of Ann-Hari and reads that progress at tracks’-end is picking up again. There are questions in Parliament. The TRT and Weather Wrightby are censured for strange dealings. Workers have died in some accident, a gradient has been levelled in a way the inspectors cannot explain, and the heat-ripples and the lifeless zone for yards to either side raise questions the TRT will not answer. No one will say sacrifice, no one will say dæmon, but there is a growing sense that Weather Wrightby is a visionary of money and engineering who will not let geography or climate or politics block him. His plans are embedded in his company’s name, and they are bigger by far than this road.

Judah, Judah, Judah. He thinks his name. Something will happen.

Products are created or remembered from the Full Years. In the arts there is a languid flux. New Crobuzon is full of building, its docks with ships. Shops carry novel commodities. Beside the poster-kiosks booths appear like wildflowers, in a spate of marketing, die-stamped signs of a man holding his hand to his mouth and shouting.

-What are these? Judah asks and enters. There is a chair, an engine, a range of lettered and numbered buttons, a tube and earpiece. He reads instructions, puts his coin into the slot. There is a list of titles.

THE MAYOR’S NEW YEAR SPEECH. HE PITY IT’S A DITTY TREBUSCHAND SYMPHONETTE

And others. He summons a music-hall song, "Rather the Poorhouse," puts his ear to the trumpet and listens quite rapt to something that has been held back snapping into place, a potential energy unlocked, the unwrapping of sound with a thudding; and then he starts as a noise emerges and it is the song, some unknown chorus girl, the nuances of her voice imprisoned behind crackling but unmistakably a voice and unquestionably singing. Judah can hear all the words.

-And if it means the poorhouse dear that’s right the poor house do you hear that’s what I’ll do to stick with you to keep you near my deary dear. Judah can hear all of them trapped.

It is wax that makes sound physical. He is absolutely fevered by this. The wax can make sound wait and recur.

A new technology, the taming of time. They are using it for the endless, endless recursion of street songs. Judah wants it for another reason. He looks at the notes he made in the swamp. He is all breathless energy, and he feels New Crobuzon ebbing from him.
