She thought about what she'd found when she'd opened the SeaTac duty-free bag. Something flat and rectangular, dark gray. Maybe made from one of those weird plastics that had metal in them. One end had rows of little holes, the other had complicated shapes, metal, and a different kind of plastic. There didn't seem to be any way to open it, no visible seams. No markings. Didn't rattle when she shook it. Maybe What Things Are, the icon dictionary, would recognize it, but she hadn't had time. Masahiko had been downstairs changing when she'd slit the blue and yellow plastic with Mitsuko's serially numbered, commemorative Lo/Rez Swiss Army knife. She'd glanced around the room for a hiding place. Everything too neat and tidy.
