I think I've read every Carl Hiaasen novel written. Some border on the utterly insane, like Double Whammy, Native Tongue,and Stormy Weather. A very few border on the halfway serious, like Skin Tight.
Others are somewhere in between the "halfway but not completely there" normality of Skin Tight and the "utterly insane" of Double Whammy and Stormy Weather. Basket Case falls in this middle category.
I say this because it seems to be heading toward utter insanity much of the book, but the final chapters return to a bit of normality rather than pushing the "pedal to the metal" nuttiness that continued through the climax of stories like Double Whammy.
The plot centers around Jack, who writes columns about the recently deceased. Jack has been demoted from a news reporter for having the audacity of telling the new owner of the paper that the cutbacks and layoffs have resulted in an inferior paper. (Presumably, rather than fire him for insubordination and risk a lawsuit, the owner figures just demote him to the obits and hope he quits in embarrassment or boredom.)
But Jack notices that a former rock star of which he was fond years ago has died locally, and he begins investigating, ostensibly to write a news column of the celebrity death, and quickly finds serious inconsistencies in the stories and strange maneuverings going on.
Hiaasen produces another cast of whacky characters, among which is a sister of the deceased who earns her living stripping in her home for Internet voyeurs, a developing romance between Jack the reporter and his younger female supervisor, and intrigue between stockholders in the newspaper corporate ownership.
Over the years, Hiaasen has figured out that his "niche" in the publishing world as an author is the comedy murder, or telling of crazy capers and creation of insane characters. Pete Hautman is another author who appears to be following in Hiaasen's footsteps and success in this genre.
