AN ADDRESS TO DIE FOR… There's a killer on the loose. And he's targeting one specific address?138 Main Street. The problem? There are over 7,000 Main Streets in the USA. And the police and FBI have no clue which one will be next. For FBI Special Agent Ben Walker and his rookie colleague, Officer Zoe Hill, the pressure to solve the case is unimaginable. There aren't enough police officers to cover every house, and vigilante residents are attacking anyone who rings their doorbell. Main Street might be one of America's most popular addresses, but for those living at number 138, it comes down to fight or flight. Then a manuscript is sent to the New York Times, purporting to be the manifesto of the "Main Street Killer" and demanding radical social change. As the effect of the terror campaign takes hold across the nation, Walker and Hill find themselves in a race against time to stop the killer. But with their target always several steps ahead, and almost 3,800,000 square miles of ground to cover, they'll have to find him first…
