Detective Lili Grimes, partner of James Gordon and Harvey Bullock, is famous of her cold heart towards criminals, or anyone in general, but under a very good poker face, there hides a smile, desperately waiting for someone to find it.

Or a totally sane detective and a psychotic killer fall in love ao3: augustine25
