Harper Collins is proud to present its new range of best-loved essential classics. ' All human beings as we meet them are commingled out of good & evil.' After taking an elixir created in his laboratory mild mannered Dr Jekyll is transformed into the cruel & despicable Mr Hyde. Although seemingly harmless at first things soon descend into chaos & Jekyll quickly realises there is only one way to stop Hyde. Stevenson's quintessential novella of the Victorian era epitomizes the conflict between psychology science & religious morality but is fundamentally a triumphant study of the duality of human nature.
