"Come on," Filly said. She turned to lead them ahead. Shank moved to follow her lead, but again Thorvin scutted in before him. They followed Filly down the hall past Dok's office and examination room to the operating room door. Shank knew the layout, he'd been here before. The building was narrow and deep, and Dok and Filly had the first two floors all to themselves. For just two people, that was a lot of space. Shank guessed the CyberDok business must be okay. Nobody getting really rich, but nobody starving either. In fact, Filly's twisting, swinging butt looked pretty damn well-fed. And well-exercised too, not fat, not skinny, but soft and firm and nicely shaped.
