I still don't know exactly what James Crumley's The Mexican Tree Duck was about.
There's a kidnapping and drugs are being smuggled into the country. Somehow the beginnings of the dispute that is being played out traces back to the Vietnam War, but that is the extent of my understanding.
This is the second book by Crumley that I've read and I have concluded that his books are about attitude and atmosphere, rather than any coherent narrative. There is a lot of violence and heavy weapons and drug use.
I wish the the sum of the parts added up to something greater, but it doesn't. And I wish that I liked Crumley's writing better than I do, but I don't.
