If you were going to read a book about a secret organization, what do you suppose they would do?

It kind of depends on if this secret organization is good or bad (or just, neutral), and also what the world is like in that setting. Like, if it was the future perhaps there would be a secret organization that was set on changing the government, or uncovering some horrible thing (which doesn't even really need to be in the future)...And you need to know why it's secret, why would they want certain people not to know about this organization? Examplesssss::: People against other people, people against other organizations such as the government etc, people against things that are happening such as war or abortion, people trying to change something/make something like something to clone people, or go back in time... there are a lot of possibilities...Also I'm giving you some clich�d kind of ideas, but...Idk... Good luck anyway :)
