The alert from Tracey surprised him. Most of the frame-decking had been pretty simple, but this time Michael was getting a message that the Zulu Nation system he’d tried to get into was an expert system. That spelled danger. The only reason he’d checked it was because a flight from New Hlobane had arrived in JFK fifteen minutes before Serrin had fled for Frankfurt. Which intrigued him. The schedule for European and Japanese flights was exactly what he’d expected to find, but a direct flight from the Zulu capital into New York’s JFK was not. That startling fact stood out like a grain of grit in vaseline. Now the frame was telling him these Zulus had some serious design work in their police systems.
