detective
(I just finished re-reading Faye Kellerman's The Beast, where the body of a reclusive billionaire is found being guarded by his agitated pet tiger -- who hadn't killed him, just pawed at him a bit trying to get her owner to wake up and feed her, like any pet cat would. The police have to call in animal control to shoot a tranquilizer dart into her and take her away to a wildlife sanctuary before they can finally approach the body and start detecting.)
