Wink of An Eye (Gypsy Moran) by Lynn Chandler Willis

Michael ''Gypsy" Moran returns home to the town called Wink after a few years as a PI in Vegas. One of his sister's students' dad has killed himself... At least that's the official story. Gypsy is asked to unravel the truth about this death, an investigation that has him investigating the sheriff's department and missing female illegal immigrants.
Aside from those investigations he also has to deal with his ex-wife making life hard for him as well as his feelings for a beautiful reporter...And then there's this nasty snake.
This is the winner of this year's PWA Best First Private Eye Novel, so it has to be good, right? Right.
What this one has going for itself are a PI that is very human and fallible, but still a good professional investigator AND some pretty good character development / depth.
Lynn writes in a very convincing male voice, but manages to give it all just that bit extra with her female insights, making the female characters just that extra bit believable.
