The Killer. The Strange Story of Dr. Jekyll and Mr. Hyde.

Robert Louis Stevenson (1850-1894) was an English writer of Scottish descent, poet, author of adventure novels and stories, and the leading representative of English neo-romanticism.

The tale "The Killer" (or "Markheim") and the story "The Strange Case of Dr. Jekyll and Mr. Hyde" are united by the theme of evil that gains freedom due to the split personality of the characters.
