This story by Charles Stross is a great read. It is put across as factual, and throws in some real and possible unreal chemicals in to the story about space craft propulsion systems and possible unhand things US and Russians (in this story) did to get ahead in the space race. The story revolves around a group of rocket scientists at a party discussing the weird propulsion system they worked on, or pretended to work on to trick their opponents with misinformation.
If you looking for a good, tongue-in-check read this is worth a look, especially at 35p (in the UK) on the Kindle.
