Interesting, that description gives me very strong "Dexter" vibes, and I loved "Dexter", both the TV series and the books.Dorsey is similar to Hiaasen but way more crazy! If you don't mind a main character who is a psychotic serial killer off his meds with an addiction to Florida history with a strong moral code, you may enjoy these books! There is lots of sex and violence and laugh out loud stupid situations. Serge is a whacko anti-hero who fights injustice with his sidekick, Coleman, who is perpetually stoned. I have read several of the series and always find myself grinning or out right laughing while reading.
I also like Hiaasen but thought he was pretty crazy already.
