As always, potential spoilers ahead.
Not good. It tried to be like a James Elroy William Faulkner novel, but without sympathetic characters.
It tried to be stocking with the murder couple, but nothing new there.
The whole thing was improbable. That this much stuff could happen to so few interrelated characters, was not believable.
Whatever moral it seemed to convey was lost on me.
Maybe the book was better, but why risk it?
