I've got an idea for writing a thriller. The idea would be for the protagonist to stop the antagonist from doing a dastardly deed (with huge implications for humanity). So yeah, my protagonist tries to stop the antagonist, but I'm kind of stuck for how to do it. I mean, does my protagonist just keep coming up with ways to thwart the antagonist's plan? And how is my protagonist going to do that sort of thing with a sense of logical progression to it?

Thanks.
