She feels a flicker of attention. Her eyes skitter across the landscape, chasing something almost certainly inside her head. What has her subconscious picked up on, in that brief reverie, that is trying to elbow its way into her thoughts? (Speed limit sign. Newsagent. Community centre, run-down and covered in graffiti tags. Rubbish bin, overfull.) Investigation is a webwork rather than a line. A crowd rather than a single individual. (Parked cars. Parked bikes. Vandalised public access terminal. Blood on the pavement: a nosebleed, a fist fight, certainly nothing serious.) What thread is she looking at that, viewed from another angle, might be a net? And a net to do what? To catch whom?
