The strange case of Dr Jekyll and Mr Hyde
Part of the Pocket classics series
Published in 1886, Robert Louis Stevenson drafted The Strange Case of Dr Jekyll and Mr Hyde over just a few days while confined to bed.
It can't be known whether this feat of writing drove him into a fever, or if his illness inspired the feverish plot.
But this background helped to justify at the time the invention of Mr Hyde, the terrifying alter ego of a respectable man, whose depravity was so extreme that his worst criminal pleasures are tantalisingly omitted from a still violent story.
At first shunned by booksellers, Jekyll and Hyde went on to be quoted as a moral allegory and enjoyed by an enormous public.
It remains a frighteningly compelling crime thriller with an enduring vision of the dark side of the psyche with an unforgettable plot which puts it at the head of its genre.
