Eden in Winter by Richard North Patterson
Benjamin Blaine fell to his death from a cliff on Martha’s Vineyard. Was it an accident or was he pushed? Adam Blaine, the deceased son, returns from his job in Afghanistan for the inquest. Through less than honest means he discovers that his brother will likely be indicted for murder. Adam delves into family secrets and makes shady deals to make sure his innocent brother stays free.
This was good choice on audio because the reader reads Adam’s parts devoid of emotion, which is true to character (and we find out why). Emotion does start to enter his voice as the story, and Adam, grows.
If you enjoy dysfunctional family stories, the Blaine family is one of the most dysfunctional ones ever. The author does keep you guessing how things will work out for all the members of the family but this is not a mystery; you know what happened to Benjamin quite early on in the story.
