After a couple of minutes, I twisted around again and unfastened the grav harness, then slid carefully through the hatch and hit a steel grid walkway with the heels of my hands. I curled the rest of my body slowly out of the hatch, feeling like a moth emerging from a chrysalis. Checking the darkened walkway in either direction I rose to my feet and removed the stealth suit helmet and gloves. If the keel plans Irene Elliott had Dipped from the Tampa aeroyard stack were still accurate, the walkway led down among the huge helium silos to the vessel's aft buoyancy control room and from there I'd be able to climb a maintenance ladder directly onto the main operating deck. According to what we'd patched together out of Miller's interrogation, Kawahara's quarters were two levels below on the port side. She had two huge windows that looked downward out of the hull.
