Hello, please suggest a book which has two people from different walks of life fighting against a common enemy. These two can be doctor and police officer/detective or a scientist and law enforcement officer fighting to stop a serial killer or a rogue organisation that wants end humanity. These are just some examples. Bonus points if the duo is male-female. Book doesn't need to have romantic overtones between the main characters.
I've already read books by David Baldacci, Steig Larsson, Dennis Lehane and Arthur Canon Doyle. I'm not looking for YA recommendations.
Thanks in advance!
