... whodunnit on Diagnosis Unknown, on Discovery Health as I type this: it's almost always someone poisoning someone else, and the poisoner is the person who was not interviewed for the show. It's incredibly obvious once you know what to look for, like figuring out if the person the cops have nabbed on [insert cop show name here] is the person whodunnit based on how far into the episode it is: if it's 20 minutes in, it's a wrongful arrest. At 50 minutes in, it's the true perp.
