At the corner half a dozen men huddled around a brazier, talking and laughing, tin mugs of tea in their hands.

"Not sure as I like so much change," Sutton said dubiously. "Still, can't be 'elped."

Hester did not argue. They had only a few yards further to go before she saw the vast crater of the new tunnel. It would carry not only the sewer but beside it the gas pipes for the houses that had such luxuries. Skeletons of woodwork for cranes and derricks poked above it like fingers at the sky. There was a faint noise from far within of grinding and crushing, scraping, slithering, and the occasional shouts and the rattle of wheels.

Hester stood on the freezing earth and felt the freshening wind from the tide on the river, with its smell of salt and sewage. She turned to her left and saw the roofs of houses in the near distance, and closer, the broken walls where they had been flattened to make way for the new works. To the right it was the same, streets cut in half as if they had been chopped by a giant axe. She looked at Sutton and saw the pity in his face, as well as the fury he was trying to suppress. To build the new they had broken so much of the old.

"Keep close and don't meet no one's eyes," he said quietly. "We'll just walk through like we got business. There's 'em as knows me." And he led the way, making a path through the rubble and keeping wide of the groups of men. Every now and again he put out his hand to steady her, and she was grateful for it because the rubble was crumbling and icy. Snoot trotted along at their heels.

There was a thick fence around the actual pit in which the men worked, possibly to keep out the idle and to prevent the careless from falling in.

"Got ter go round the end there." Sutton pointed and then led her through a shifting, slithering wasteland of debris. The line of pipes was easy enough to trace with the eye by the wreckage that lay in its path. Twice they were stopped and questioned as to who they were and if they had any business there, but Sutton answered for them both.
