I've noticed some common themes across the three generations: police/crime careers, a tendency to be overweight, and vodka. Definitely vodka.
I don't understand why, in a family of cops, it took 50 years and Audrey to determine the actual events of Stan's murder. I enjoyed the whodunnit aspect of the book, but cringe when I think of this family. I intensely disliked Audrey and moderately loathed Jim. Stan lied about his brother, Jim lied about Audrey's parentage, Audrey doesn't tell her family she has a child. And quit with the vodka already, you've got major problems.
