Dr. Jekyll and Mr. Hyde

Dr Jekyll, a "large, well-made, smooth-faced man of fifty", occasionally feels he is battling between the good and evil within himself, thus leading to the struggle between his dual personalities of Dr Jekyll and Mr Hyde. He has spent a great part of his life trying to repress evil urges that were not fitting for a man of his stature. He creates a potion in an attempt to mask this hidden evil within his personality.
