I listened to this one on Audible. It was a fun mystery and made me want to take a tour in San Francisco.
I really enjoyed the back and forth of the present mystery and the researching the truth about the past. 
The narrator does a great job with this one. I really enjoyed the side characters and the twists. Some points were predictable but I'm not mad at it and it didn't keep me from enjoying the story.
I want to call this one a light hearted murder mystery, is that a genre?
