I WAKE UP, STARTLED. Was that a sound? I sit up, peering around me in the dim shop. The light outside is fading fast. This is February in England, after all, and it'll be completely dark outside by five o'clock. I hold my wrist an inch from my nose, trying to make out the position of the hands on my watch. Ten past four. I need to find a light switch, or I'll soon be sitting in the dark, and I so do not fancy that. By the counter seems the likeliest spot. I get to my feet and start picking my way around the displays as best I can, trying to avoid obstacles. I don't entirely succeed, managing to trip over a low table displaying selected works of Shakespeare. I pick the books back up off the floor, and carry on. I fumble around the walls beside the till, and come up with nothing. Somewhere
