Read excerpt 1 from The Strange Case of Dr. Jekyll and Mr. Hyde.

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. . . . Mr. Utterson at last turned and looked at his companion. They were both pale; and there was an answering horror in their eyes.
