Robert Louis Stevenson's gothic novella The Strange Case of Dr. Jekyll and Mr. Hyde was originally published in 1886. It drew on Stevenson's interest in the psychology of good and evil. The story became entrenched in modern literature, and the term "Jekyll and Hyde" has become a common expression for people of variable disposition. The author appears to have written the story in just a few days while either ill in bed or high on drugs - accounts vary.
The book is worked in a combination of black and red, where black represents the conservative and traditional Dr. Jekyll, and red represents the evil Mr. Hyde. This is especially represented on the endpapers and the cover.
Jekyll and Hyde consists of 240 pages, with overall dimensions of 76 x 60 mm (3 x 2-3/8 inches). It is priced at $45 each plus $7 shipping and handling.
