I just finished watching Season 2 of Luther, and the main detective in it ends up completely changing the course of this one girl's life. It was pretty striking, because she started off the season as a basically an indentured sex worker.

That got me thinking: wow, he really changed the course of her life! And not because of chance or because he introduced her to someone and they got married or something... but because he really went out of his way to help her and to turn her life around. And she did.

Have you ever changed the course of someone's life like that?
