Death of a Corrupt Man (French: Mort d'un pourri), also known as The Twisted Detective, Death of a Louse and Kill a Rat, is a 1977 French political thriller directed by Georges Lautner and starring Alain Delon.

The film score was composed and arranged by Philippe Sarde and features saxophonist Stan Getz fronting the London Symphony Orchestra and the soundtrack album was first released on the French Melba label.

This time, Sarde, who always closely follows the editing process, suggested that they needed a strong soloist, preferably a tenor saxophone player, who would serve as a musical counterpart for the actor Alain Delon's famous good looks.

Watching Getz's performance, Lautner decided to find a way to put the musician in the picture.

Sarde's instincts were right—Getz's saxophone gave the soundtrack a lyrical, nostalgic quality—fitting for Alain Delon's quest in the film for the sake of the past, to honor the memory of his dead friend".
