After a complete interrogation dressed like a casual conversation, Louise had got information on everything between Heaven and Earth. Only some of the information was interesting, though. After the so-called conversation (it was hard enough for Louise, how did normal people even get out of their beds?), Martine had magically forgot about needing the FireStopper, and was walking down Diagon Alley, unaware of the silent memory charm that was a speciality of Ravenclaws who liked to sneak around at night without getting detention.

Louise knew that she had to get into the Ministry of Magic. After that, assuming that nobody had killed her yet, she had to get into Potter's office. It wouldn't be child's play, but if anyone was ever going to do it, it would be her. Getting into Potter's office wouldn't be too hard. The hard things, the ethically questionable actions, were what she was going to afterwards. She hoped Potter survived. Not that she actually liked him. Luna did. Hermione did. Ginny did, and probably a certain Longbottom too.

She couldn't kill Potter. There had to be another way. It had all seemed so easy at the university. She had planned out everything from her upcoming visit to Knockturn Alley to which spell she would use to get rid of the Head of Auror Office. It hadn't occurred to her, not even for a moment, that the current Head of Auror Office might turn out to be an acquaintance of her. Complicating matters even further, his best friend was Minister of Magical Law. Great, just incredibly fantastic, wasn't it? By killing Potter she'd lose all her contacts in the Magical World. She would have hurt her three best friends more than normal people could imagine. Also, she would have given Ravenclaw House a worse reputation than Slytherin.

When she sat down at her bed in the Leaky Cauldron that night, she had still not figured out exactly what to do. She couldn't use a Polyjuice Potion – according to her sources, the first thing Potter had done after becoming Head of Auror Office, was making the Ministry Polyjuice-proof. She knew why – Hermione had told her everything about their adventures of 1998. From Fleur Delacour's wedding to defeating Voldemort, it made life at Hogwarts seem ordinary. Which it was, but not compared to muggle summer school or university.

What Louise did not know, was that her chance to infiltrate the Ministry would turn up the next evening. What will she go with, ethics and honesty, or effectiveness?
