The Day Of The Jackal

I need to know the theme of the book "Day of the Jackal" (main theme). So I need the name of any other source of entertainment (film, book, song, picture, etc.) on the same theme. HELP PLZ!

It is a conspiracy to assassinate President Charles de Gaulle of France. The hit man for the job is called the Jackal The Jackal = French and has a lot of false identities. An inspector from the relentless tracks and kills him just before he kills General.
