Go Find Daddy by Steve Goble is a recommended investigative novel and the third book featuring PI Ed Runyon.
Ed Runyon is hired by the wife of a man wanted for murder. She wants Ed to find him. However, the case isn't quite as simple as that. A cop was found murdered in rural Ohio on Donny Blackmon’s property and Donny has disappeared with no way for anyone to find him. His wife needs to find him because she has just learned that their daughter is dying from cancer. Once the young girl asks Ed to find her Daddy, Ed knows he's taking the case.
You can still follow the plot and won't feel as if you are missing too much backstory, but as
the third book in the series, it might behoove readers to start with
the earlier two novel, City Problems and Wayward Son. Additionally, Ed can be a bit of an annoying character and his personality may not endear him to some readers.
All in all, this is a decent PI novel, not a favorite, but not awful.
Perhaps I would have liked it more if it was just a story and kept
current events out of the plot. This element to the narrative is
tiresome and dates the novel immediately, before it is even released.
