The Sunday Walk Revisited
Passing the Door
Utterson and Enfield again walk past the by-street door. Enfield remarks that the story is at an end, but Utterson is uneasy. He suggests they look at the windows of the court.
The Court
The court is cool and damp, full of premature twilight. The middle window is half open, and they see Dr. Jekyll sitting there, looking like a disconsolate prisoner.
A Brief Conversation
Utterson calls out, and Jekyll responds that he is very low. He refuses their invitation to walk, saying he dare not. But he is glad to see them.

The Sudden Terror
The Smile Dies
Jekyll's smile is struck out of his face and replaced by an expression of abject terror and despair. The window is instantly thrust down. The two men are frozen with horror.
The Aftermath
They leave the court in silence, both pale. Utterson exclaims, 'God forgive us, God forgive us.' Enfield nods solemnly. The incident is over in a second, but it leaves a lasting impression.
The Meaning of the Terror
This glimpse of Jekyll's terror is the first direct evidence that something is seriously wrong. It foretells the final crisis that will lead to the last night.
