Looking for a fic i read a while ago, the only things i really remember were that, somehow someway, Harry ended up in another universe and he seduced or slept with Narcissa for information and killed Lucius by blasting him out of a hotel balcony enough stories up for him to die and Dumbledore assuming HP wasn't such a good guy for killing a man just to sleep with his wife..... thanks for the help if you can, thanks if you can't either way....
