When a serial killer targeting Muggleborn women appears in Britain, Behavioral Analysis Unit profiler Hermione Granger searches for any indication of who this monster and his next target may be. She finds herself forced to work with none other than Draco Malfoy, Improper Use of Magic analyst. Can they cooperate long enough to catch a killer? Or will they become trapped in his game?

She had changed. Gone was the Lily of sixth year, and every year prior to that. Gone was the good girl who insisted on canceling post-Quidditch parties, much to everyone's disdain. She was changed. Broken. And it damn near broke James' heart.

The Malfoys, on principle, do not believe in owing anyone favors. A post-war Draco Malfoy found himself owing quite a few people for his release from Azkaban.

Lily and James' bickering doesn't necessarily lose heat, just gains it in a way neither of them expected. Smut one shot. Finished.
