Mexican Crime
Not what I was after
I picked this up before our trip to Mexico but didn't find the sense of place I was after. It was certainly crime noir though with a Mexican touch of phantasmagorical (with lurid dream sequences).
The time swings between the crime happening in the present and an author investigating an earlier crime. The narrative for both stories is overloaded with corruption (everyone ... police, politicians, businessmen) .... all a bit heavy.
