Okay, let’s do this the smart way instead of the stupid way. I tilted the safety light down to point at the platform and looked at the battered surface. No dust down here to show footprints, but it was clammy and a layer of faint dampness clung to the metal. I got down and put the side of my head against the platform, as close to eye level as I could get, and increased magnification. Then I started cycling through all my vision filters, including the ones I’d never had to use before.
