The monster strangles little William.

[Little William speaking] “Hideous monster! let me go; My papa is a Syndic — he is M. Frankenstein — he would punish you. You dare not keep me.”

[The monster speaking] “‘Frankenstein! you belong then to my enemy — to him towards whom I have sworn eternal revenge; you shall be my first victim.’ The child still struggled, and loaded me with epithets which carried despair to my heart: I grasped his throat to silence him, and in a moment he lay dead at my feet.”
