The air inside the shop felt cooler on his fingertips and smelt of pipe-smoke. He had no choice but to stare through the glass for about five seconds. In the architect’s mind’s eye, this had probably been a lovely shop-window where ladies would coo over pretty displays. And maybe it would be that some day, if Hockley-in-the-Hole ever became fashionable. But for now a board had been put up inside of it, a bit more than arm’s length inside the glass. Daniel couldn’t tell whether it was a backdrop for display, or a barrier against intruders. It had been covered with green fabric a long time ago, and the fabric had been bleached by the sun, as this was a south-facing window. It had gone nearly white everywhere except where the sun’s light had been blocked by wares, hung on that board for display. No wares remained on it now. But their caught shadows were clearly visible. Daniel’s first thought was pendulums, because the shapes were circular, depending from slim cords. But no one bought pendulums save Natural Philosophers and mesmerists. It had to have been watches, hanging on chains.
