This GCSE English Literature quiz takes a look at language. Language in Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde draws on science, psychology, a fascination with the mystic and the spiritual, the conventions of civilised society and the seedy side of nineteenth-century London. Descriptions are often poetic, sometimes visceral. Stevenson creates a sense of a dark and mysterious London, even when describing events which take place in daylight or inside comfortable homes, in front of homey fires. Descriptions often hint at unseen, inexplicable realities beyond the edge of reason.
