Seriously, that sounds like a great idea for a show. Or a variant: Main character is an elected coroner who doesn't know shit, and won the election, against a more qualified candidate, via sleazy politicking. During the course of the show s/he has to investigate a sudden outbreak of murders, which could be the work of a serial killer, or might be committed by multiple individuals. S/he has no earthly idea which, and tries frantically to cover up his/her own incompetence while simultaneously seeking help anywhere available -- the Internet, clandestine calls to pathologists, etc. Eventually s/he tries to pin a murder on the most likely suspect, then discovers after an arrest is made that it's definitely the wrong guy. And so on.
