Assassins and Lovers (http://www.fanfiction.net/s/1358190/17/) has a ADMM thing as somewhat of a sidebar... I sometimes find EvieBlack a little repetitive (she has several similarly themed fics) but I loved this one. I would highly recommend it, just for the humour and the delightfully written Dumbledore. (And take it from me: I rarely manage to finish a 17-chapter fanfiction.)
