"The Strange Case of Dr. Jekyll and Mr. Hyde" Stevenson's famous exploration of humanity's basest capacity for evil, has become synonymous with the idea of a split personality. More than a moral tale, this dark psychological fantasy is also a product of its time, drawing on contemporary theories of class, evolution, criminality, and secret lives. Also in this volume are "The Body Snatcher," which charts the murky underside of Victorian medical practice, and "Olalla," a tale of vampirism and "The Beast Within" which features a beautiful woman at its center.
