Miss Marple at Glamis

My English course for this year is Shakespeare. So far, we have covered Henry V, Hamlet, touched on a few sonnets, and now are working on Macbeth, a work of which I am incredibly familiar. At the end of each play, we are assigned a paper or project. One of the options that I have, is to write a fictional story involving the plot of Macbeth, and what would happen if a famous detective visited the castle in order to solve the murders of Duncan and/or Banquo. I have chosen the fabulously British Miss Marple as my detective! This is why, instead of more educational tasks, I am going to be watching Miss Marple DVD's, and reading a few of the works by the creator of Miss Marple, Agatha Christie, instead of, say doing another lesson of French. (I can order coffee, so what else is there?) Isn't the castle lovely?
