"Hello," Laney says, his fingers finding the handle of a mechanical flashlight from Nepal, a crude thing, its tiny generator driven by a mechanism like a pair of spring-loaded pliers. Pumping it to life, he raises it, the faintly fluctuating beam finding the cardboard ceiling. Which is plastered, inch by inch, with dozens of stickers, small and rectangular, produced to order by a vending machine inside the station's west entrance: each one a different shot of the reclusive Harwood.
