At the top, I cracked my head in the dark. I felt for the latch, lifted the panel, and pulled myself up into the stifling heat of the dark, cramped room Severance had fitted out as my forward command post. It wasn't much to look at-a seven-by-twelve-foot space, low-ceilinged, blank-walled, with a grimy double-hung window at one end giving a view of irregular black rooftops, and, far away, tall palms like giant dandelions against a sky of luminous deep blue.

I closed the shutters and switched on the ceiling light. A steel locker against the wall opened to the combination Severance had given me; if I had made an error, a magnesium flare would have reduced the contents to white-hot ash.

I pulled the door wide, took out a limp, fish-scale-textured coverall with heavy fittings molded into the fabric at the small of the back and the ankles. I pulled off my jacket, struggled into the garment. It was an optical-effect suit-one of the CBI's best-kept secrets. It had the unusual property of absorbing some wave lengths of light and re-emitting them in the infra-red, reflecting others in controlled refraction patterns. It was auto-tuned over the entire visible spectrum, and was capable of duplicating any background pattern short of a clan Ginsberg tartan. I couldn't walk down le Grand Cours in Paris in it without causing a few puzzled stares, but in any less crowded setting it was as close an approximation of a cloak of invisibility as science had come up with. It was the Cover Lab's newest toy, and was worth a hundred thousand cees in small, unmarked bills in any of the secret marketplaces of the world.

The second item I would need was a compact apparatus the size and shape of an old-style cavalry canteen, fitted with high-velocity gas jets and heavy clips that locked to matching fittings on the suit. I lifted it-it was surprisingly heavy-and clamped it in place against my chest. Broad woven-wire straps stitched into the suit took up the weight. I tried the control-a two-inch knob at the center of the unit.
