Motherlode by Thomas McGuane

David, David, David....
What was he thinking?

 I'll tell you what he was thinking! David was probably thinking the same exact thing I was. Somehow we were going to get rid of Ray not by murdering him or anything dramatic but just by exposing him as a fraud.   I figure in some uncomfortable way he would just leave.  ( I thought Morsel would no longer be interested in him when he said, "do you want some of this"?   Joking or not, that was inappropriate! ) David and Morsel would then hook up and live happily ever after! Rich on the farm, Have the plane and maybe do an occasional drug deal and live a comfortable life.
Not perfect or 100% ethical but when they later revealed that her dad was becoming more dependent and incapable of caring for himself I figured they could take care of him.
 Though this was a fiction story, I feel like it had a lot of reality in it. A "simple drug deal" eventually goes south  when Ray and Morsel are doublecrossed catching David in the crossfire and if you live by the sword you die by the sword.
 A little long but well written… And though I believe my preference is to have a clean happy ending I feel that this at least made sense and left no loose ends, except for David's Mom will never know what happened to him.
