Just past Sixty-ninth Street, Shank slowed the stepvan, flipped on the amber warning blinkers, and swung the vehicle across the boulevard. He drove the truck, one wheel at a time, up over the curb and onto the gold-lit plaza set in front of the imposing headquarters of Shiawase Compudyne, a division of the Shiawase Corporation of Kyoto, Japan. There was one very important feature of Compudyne's North American operations. Rico stepped from the stepvan to find it right there beside the truck. Set amid the golden tiles of the plaza was the round black insert of a manhole cover.
