Query: A return to the original

Valerie Martin returns to the original ideas of Stevenson's Dr. Jekyll and Mr. Hyde by eliminating the girlfriend figure which quickly found its way into adaptations beginning with a play only a few years after the original. Valerie Martin also returns to the original by allowing her readers to see the world which Stevenson attempted to write about by emphasizing class/race/gender distinctions and showing the dual nature of England of Stevenson's time. Martin, intriguingly shows more of Mr. Hyde than the original allowed the audience, thus drawing in fans of the original and exciting first-time readers. This book is a must-buy for anyone who enjoyed the original or the 1991 play by David Edgar.
