Problem: Neil McCaw's short film (posted under Week 3) describes Sherlock Holmes as a 'palimpsest.' McCaw clarifies that "a palimpsest is a cultural text repeatedly altered over time as each new interpretation becomes superimposed over those that precede it." Describe how the modern BBC series portrayal of Sherlock Holmes in "A Study in Pink" is different from the original Sherlock Holmes in "The Adventure of the Speckled Band," with detailed references to both texts. Include changes to Dr. Watson and Mrs. Hudson too, if any.
