Native Tongue by Carl Hiaasen
Rare and exotic animals are stolen from the Amazing Kingdom of Thrills zoo on North Key Largo by ruthless thugs...thugs with much bigger, and deadlier, things in mind than the creatures they've already kidnapped. The Amazing Kingdom's PR man Joe Winder, a burned-out, ex-muckraking reporter, wants to find the thieves. Who are they, and what is their true motive? As Winder follows a series of weird and lethal events, he has no idea where his search will lead...until it's damn near too late.
