Scene from The Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson, 1927. Mr Utterson, reading Mr Hyde's letter to Dr Jekyll, recognises that the writing is the same as Jekyll's and realises the two men are, in fact, one. Jekyll had succeeded in separating out the duality in his nature, Hyde representing pure evil and Jekyll good, but eventually the antidote to the Hyde persona ceases to be effective. From The Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson. (London, 1927). First published 1886.
