She pulled him to a stop at the DORD scanner, a heavy machine nearly as big as some of the cars out rusting in the parking lot. This was the big gun in her laboratory arsenal: a medical scanner that could catalog an entire body, layer by layer and piece by piece. She hit a switch to turn it on, then crossed back to the medicomp while it booted up. The definitions she’d created for the categories of compounds were still there, along with several of the clearest images, and she froze them to the screen before sliding the screen out, disconnecting it from the medicomp, and carrying it carefully to the DORD. The screen had an impressive amount of computing power all on its own, but it was nothing compared to the sensor systems it could attach to. She slid it into the DORD, hearing the click as it locked into place, and a few quick finger taps later the machine was ready to go. The DORD would scan Samm’s lungs, throat, and nasal passages for anything resembling the mysterious compounds, which would give her a good idea of where they came from and where they went. She’d have to intuit the rest from there. Kira raised the sensor array, swung it out, and centered Samm beneath it; it was a thick, heavy piece of equipment in a white plastic shell, easily the heaviest thing in the room, but it held its own weight perfectly. She tapped start, and the DORD whirred to life.

Kira watched the screen closely, eager to see what the scan turned up. It was not a quick scan. She drummed her fingers nervously on the DORD housing, then turned and walked to the window; she wanted to ask Samm if he knew what the particles were, despite his refusal to talk, but now that the scan had started, any significant motion would upset it. She turned again and watched him, steady as a rock, almost as if he were holding still on purpose.
