Tourist Season is a 1986 mystery novel by Carl Hiaasen that's heavier on the dark humor than on the mystery. It's been over 4 years since I last read this book, and I am re-reading it now because it takes place during the month of December. This is an easy breezy book, not subtle by any means, but fun.
from the back of the book:
The only trace of the first victim was his Shriner's fez washed up on the Miami beach. The second victim, the head of the city's chamber of commerce, was found dead with a toy rubber alligator lodged in his throat. And that was just the beginning... Now Brian Keyes, reporter turned private eye, must move from muckraking to rooting out murder... in a caper that will mix football players, politicians, and police with a group of fanatics and a very hungry crocodile.Kirkus Reviews closes with this: "...if you like your gallows laughs with gall, this could be for you."
