for YA there's I Hunt Killers by Barry Lyga which is about a teen whose dad was a serial killer and he sets out to catch a killer. There's also The Silence of the Lambs by Thomas Harris which shows the relationship between Hannibal and Clarice.

TV Series:

The Mentalist (GREAT SERIES if you like SVU and Lisbon and Jane's friendship and sexual tension is a highlight of the show), Hannibal, Rizzoli and Isles (great female-type "bromance (not sure what the term is when its two femals best friends), Elementary (Holmes and Watson have a great partnership and it has excellent story lines).

It's an older series, but Ed McBain's 87th Precinct novels remind me a lot of Law and Order. It's a great series, and there are over 50 titles.
