Not sure in what world this story would be believable, but that world is full of idiots.
I love books because they make the unbelievable believable. Wizards, faster than light space travel, dragons, people with a healthy understanding of their and other's feelings; all these and more become real when reading a good book.
But then there's the offenders who kill this illusion. Until Proven Guilty isn't the worst offender, but it doesn't make logical sense which took me out of the story too many times. I love lists, as you well know, so let's enumerate.
1. Articles in the daily newspaper are used to help drive the story, but the articles are very specific to the crime and the non-public figures involved. Way too specific. If you were to read them in a real paper you'd wonder if there wasn't a mistake and someone had just started publishing rumors they heard about their neighbors. The articles would be more at home on my grandmother's facebook page than a large city newspaper.
2. The main character, a police homicide detective, isn't good at his job. He even openly breaks the law to get evidence that can't be used.
3. The most beautiful woman in the world, who's also super rich BTWs, falls madly in love with the prematurely aging, pudgy, poor detective. And our main character detective doesn't find anything odd about this. Not even when she wants to get married one week after meeting. I get love is blind, but this is blind, deaf, and lacking any sense of smell or touch.
4. You know who did all the murdering. It's not a mystery. There's no red herring.
The story takes place in Seattle, so as a Seattle native it was fun to read all the descriptions of early 80's Seattle. Most surprising to me is that there has always been a McDonalds on 3rd Ave and it has always been seedy. It's good to know some things don't change.
