Scientist Dr Jekyll discovers a way of changing his personality and becoming the violent and aggressive Mr Hyde. At the start, moving from one to the other is easy. But not for long. Both a psychological investigation and a thrilling story, the double nature of the hero has made him an iconic figure in literature. The tempestuous nature of the tale makes it an ideal title for the Young Adult Classics series. This is part of the ‘Young Adult Classics’ series launched by Naxos AudioBooks in 2009: each title contains a CD-ROM with extensive ‘teacher notes’ and the full text of the audiobook.
