“All human beings, as we meet them, are commingled out of good and evil: and Edward Hyde, alone, in the ranks of mankind, was pure evil.”

Are we humans really composed of two different personalities housed within the same brain, within the same person? The Strange Case Of Dr. Jekyll And Mr. Hyde is a gothic novella by Scottish author Robert Louis Stevenson, first published in 1886. The novella is about a London legal practitioner named Gabriel John Utterson who investigates strange occurrences between his old friend, Dr. Henry Jekyll, and the evil Edward Hyde.
