A series of mysterious and increasingly alarming crimes are taking place across London. People are being injured, even murdered without mercy and without reason. And yet, the perpetrator cannot be found. The crimes happen overnight, but in the morning the murderer is gone "like breath upon a mirror". Mr Utterson (a lawyer), Dr Lanyon and Dr Jekyll each bring their insights to this sinister conundrum. Robert Louis Stevenson's classic story of Dr Jekyll and Mr Hyde is brought to life with a cast of voices in this dramatic reading. Only 10 chapters long, tradition says that Stevenson wrote the novella in less than a week, yet the central idea of the duality of human nature continues to fascinate through the ages!
