Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde.

But the words were hardly uttered, before the smile
was struck out of his face and succeeded by an
expression of such abject terror and despair, as froze
the very blood of the two gentlemen below. They saw it
but for a glimpse for the window was instantly thrust
down; but that glimpse had been sufficient, and they
turned and left the court without a word. In silence,
too, they traversed the by-street; and it was not until
they had come into a neighbouring thoroughfare,
where even upon a Sunday there were still some
stirrings of life, that Mr. Utterson at last turned and
looked at his companion. They were both pale; and
there was an answering horror in their eyes.

How does this passage develop the theme "Evil can
never truly hide itself"?

Dr. Jekyll tells the men to go away before slamming
the window closed.
Dr. Jekyll closes the window and makes the men
nervous by following them home.
Utterson and Enfield are horrified when they see
Jekyll's transformation.
Utterson and Enfield are ashamed that they did not
stay to help Dr. Jekyll
"God forgive us, God forgive us," said Mr. Utterson.
