An intriguing combination of fantasy thriller and moral allegory, The Strange Case of Dr. Jekyll and Mr. Hyde depicts the gripping struggle of two opposing personalities — one essentially good, the other evil — for the soul of one man. Its tingling suspense and intelligent and sensitive portrayal of man's dual nature reveals Stevenson as a writer of great skill and originality, whose power to terrify and move us remains, over a century later, undiminished.
