'Jekyll and Hyde': examining the novella's structure

Stevenson uses conventions of epistolary fiction to foreground the importance of letters and documents. Letters provide clues as part of the detective plot, but also link to the theme of concealment. The secrecy created by the epistolary form could represent the upper classes attempts to conceal unsavoury behaviour. The majority of the novella is told in the third person limited, focalised through Utterson. A sense of mistrust is created through unreliable narrators and a non-linear narrative.
