Who Dunnit?!

Thanks, I had this idea that it was pretty suspicious that Angela Langsbury would be present at all those murders, I mean had she been in the police it would have fitted her job descriptionbut since her character in Murder She Wrot was just a writer then suspicions should be raised, perhaps a new series that shows her to be a blood thirsty serial killer who frames others so convincingly that even they think theyve done it. But I couldnt stop there, so I got the idea that most early murder mysteries were marketed to the upper classes when they were written (if for no reason other than the upper classes could read) so I had the words 'bourgois feaces'. Callahan and Columbo got in because I like them
