Need help starting my espionage sci-fi story... again Im writing a graphic novel about a secret service officer named Martin who works for a megacorperation called Echelon. It opens with a the agency finding massive intelligence leaks within from agents who are selling secrets that put the corporation at risk. Echelon has its hands in government and governs Dodge city with an iron fist. Dodge city is enclosed within a massive dome structure that prevents people from entering or leaving undetected and there are strict laws that prevent people from leaving. Echelon senses that a foreign agency is buying off their agents and promising them a new life outside of DC. Martin must find out who is helping the agents flee the city-state. What Martin and Echelon don't know yet is that their threat uses an underground pathway in Dodge City to give politicians, researchers, and secret agents looking for asylum in other countries a way out of Dodge City. The people behind this scandal are planning to start a revolution in the city's underclass(people who are forced to live in dodge city against their will). Martin himself was forced to live in dodge city and chose to join echelon so he can soon leave (People can earn naturalization in other countries by contributing to DC's society). He hates the idea of treason because its what brought his family (who had mafia ties) to be murdered. However, Martin will soon question whether hes fighting on the right side as the possibility that Echelon had a hand in his family's systematic murder becomes more evident. Im kind of stuck at how martin finds out about the underground passage way and how he gets a lead on the enemy. I was thinking he can interogate a bar owner who has wine improted from a embargoed countries through the pathway but thats too easy.I need something sleuthy. Ive beeen researching but information on espionage is so elusive.
