"The Condor II laser microphone picked this up a few minutes ago," Mole said. "It’s still somewhat staticky, but I’ve passed it through a digital signal-enhancer to make it as clear as possible. It’s a miracle we got anything at all." Hendrix smiled at that; he’d been the one who’d made the modifications to the laser mike. The laser beam was ingeniously polarized so that it was able to penetrate the reflective surface of The Fixx’s huge hangar windows, then detect microvibrations on the surface of the leaded glass of the chateau’s windows inside.
