The legitimate business of DonCo was technology; it followed that its security system was of the latest state-of-the-art design. Although only a handful of people were authorized to know it, DonCo had recently been at the forefront of ongoing sensitive applications studies of the U.S.
Navy's newest sea-toground missile guidance systems. Every step had been taken to guard against just the sort of covert infiltration that Bolan and Gadgets were now carrying through.
The security facility at DonCo was proprietary, as Gadgets had explained to his boss during the preprobe briefing, and it employed a systems approach. This meant simply that security was on-site, tied in to a basement guardroom, and that the entire plant had been designed with counter-subversion in mind. The glass-and-steel-frame design embodied fixed windows, wired with alarms that signaled breakage, accidental or otherwise; ventilation came from a failsafed rooftop air exchanger. Every legitimate access was limited to the front door; fire doors on the other three sides opened only from the inside, and sounded an alarm even then. That much they knew before the probe began. Since, they had also encountered the close-circuit television system monitoring the grounds, the deceptively simple lock on the front door that served as decoy to a break-to-activate electric alarm, and the ultrasonic-wave-propagating equipment that crisscrossed the company's lobby with invisible soundwave tripwires.
