All around were four- or five-story brick buildings, their brick all leached and streaked with many years’ weather, tired-looking: scattered among them were council housing, ten-story blocks of flats done in pebble-dash and painted concrete, looking just as weary. These were not slums any more: not quite … though his father never tired of telling Patel and his mother how lucky they were to be able to afford someplace better. It was true enough, though it meant Patel had a three-quarter-hour commute to school every morning instead of a fifteen-minute walk.

No matter: today he was grateful enough not to have to walk more than a few minutes carrying the Book From Hell. The train for Tower Gateway came rumbling along, stopped and opened its doors. It was crowded, and Patel slipped in through the door and put the book down on the floor, bracing it between his shins lest it fall on someone’s foot and get him involved in what would probably be a completely justified lawsuit for grievous bodily harm.

The train swung south the few blocks to Tower Gateway. There Patel got out with his burden, walked along the platform and took the escalator up through the tubelike corridor that led to the overpass which avoided the mainline BR tracks: then down the other side again, and out across the open concrete plaza from which jutted several large slabs of ancient wall, not much more than fieldstones mortared together—a remnant of the old days when the City of London was all the London there was, and that tiny square mileage had a proper defensive wall of its own. Nothing to do, of course, with the other walled edifice just this side of the river…

As he went down the stairs to the underpass tunnel which dove under the traffic stream of Minories Street, Patel glanced up and caught a glimpse of crenellated tower against the clouds: one of the metal windvane-banners mounted on a pinnacle of the Tower’s outer wall stood frozen in mid-swing against the wind, then spun suddenly to point west in a gust off the Thames. Sky’s getting nasty, Patel thought. Might rain. Hope it stops by the time I’m above ground again…
