Two men: one a man of science, one a product of it.
 
When mr. Hyde shows up in the town, chaos ensues. Hyde seems uncatchable, he always slips away right before anyone can catch him. On the other side of it is dr. Jekyll, who starts behaving strangely. Are the two men in it together, or is the one leeching off of the other?
 
A classic from 1886, The strange case of Dr. Jekyll and Mr. Hyde is a story of two faces of the same coin, and through its symbolism shows us the two sides of humanity–at least, the worst of it.
