You'd probably enjoy Ayn Rand's Atlas Shrugged or The Fountainhead. Another good series would be Sir Arthur Conan Doyle's Sherlock stories, or perhaps Asimov's I, Robot anthology. A lot of Golden Age sci-fi fits that as well. In my experience, a character (especially a main protagonist) who is always rational/methodical is a sign of a weak writer: people are simply not rational or methodical most of the time.
