The Island of Dr. Moreau
How we cite our quotes:
I, too, must have undergone strange changes. My clothes hung about me as yellow rags, through whose rents glowed the tanned skin. My hair grew long, and became matted together. I am told that even now my eyes have a strange brightness, a swift alertness of movement. (21.42)
Prendick changes into a member of the Beast Folk! All the identity markers are there: the clothes, physical appearance, and habits. He's Survivor-ready.
