1962. Granite Flats, Colorado. A quiet, friendly little place...until part of the army base explodes. Is it a Soviet attack or an inside job? Who are the mysterious men in dark suits driving around town? What clandestine work is going on at the local hospital? As three young, amateur sleuths and the police chief investigate these mysteries, they begin to unravel a complex web of secrets -- and Granite Flats will never be the same.
