I guess it's like a movie franchise or a series of novels. The first one was popular. So, write a second story with similar characters. You can check find part I here: http://www.amazon.com/gp/product/B00N2RWMMW/ref=dp-kindle-redirect?ie=UTF8&btkr=1 and here: https://www.packtpub.com/hardware-and-creative/python-secret-agents Part II will be available soon. New missions. New ways to gather and analyze intelligence information assets. I should probably read some Ian Fleming or Robert Ludlum boos to get some ideas for more exciting missions. I'm more a fan of John le Carré stories which are less high-tech and more about ordinary selling out. I'm also a fan of the history of Agent Garbo and Operation Mincement. These are things that are really interesting uses of data, intelligence, and misdirection.
