Dr Henry Jekyll is convinced that inside him instincts for good vie with darker impulses. Interested in separating these competing forces within, he develops a potion that brings his evil side to the fore: the hideous Mr Hyde, who engages in wanton violence unencumbered by moral restraint. At first Jekyll remains in command of The situation, but the transformations spin out of control and his malevolent alter ego threatens to get the upper hand. What began as a fascinating scientific experiment becomes a battle to prevent unfettered evil from wreaking untold havoc. Stevenson uses multiple narratives to weave a gripping supernatural tale with an unpalatable core conceit: that base instincts lurk within us, dormant, suppressed, waiting to be triggered.
