From World War II until 1975 Special Agent Roy Mosteller served his country as a sailor and as a Special Agent with the Office of Naval Intelligence and the Naval Investigative Service.  His career involved investigating backgrounds to narcotics to catching spies.   Special Agent Mosteller is unique and provides fascinating facts about working in 1950's through the 70s and seeing change in the agency from ONI to NIS.  I hope you find his stories as interesting as I did.
