Dr. Jekyll and Mr. Hyde: Situational Irony 1 key example

Chapter 6
Explanation and Analysis—A Shock:

The supernatural elements of the plot, including Jekyll’s secret potion and ability to split his consciousness in two, allow for a kind of situational irony to arise in the last chapters of Dr. Jekyll and Mr. Hyde. That Henry Jekyll—a pillar of Victorian society in London—is the murderer of a member of Parliament and a sadistic criminal is an irony in itself. But a more specific example of situational irony is that Hyde’s pull over Jekyll is rooted in the very last place anyone thought to look: within Jekyll himself. 

Consider Lanyon’s surprise when he learns the truth, as reported to Utterson:

“ I have had a shock," he said, "and I shall never recover. It is a question of weeks. Well, life has been pleasant. […] I sometimes think if we knew all, we should be more glad to get away."
