Carl Hiaasen's characters ride and flail on little verbal hurricanes, and his literary storm shows no signs of dying down. Sick Puppy shares Dave Barry's giddy gift for finding humour in South Florida horrors, and a bit of Elmore Leonard's genius for pitch-perfect dialogue spouted smartly by criminals who are as dumb as stumps. The title of Hiaasen's eighth novel could apply to most of its characters, but it chiefly refers to an ebullient Labrador retriever named Boodle and the millionaire eco-terrorist Twilly Spree.
