Severus Snape used to think that he was the only spy capable of working against the Dark Lord. He was wrong. 12,800 words. NC-17. Snape/Fleur. Implied infidelity (re: Bill/Fleur), although that isn't the focus of the story. DH-compliant, ie: Snape's death. I assume that Fleur was 17, and thus of age, in GoF. Written for hp_springsmut.
