Where it comes from

Mary Wollstonecraft Shelley wrote it in chapter 20 of Frankenstein; or, the modern prometheus. Here is the prose either side of it, with the sentence you are solving left out.

"The hour of my irresolution is past, and the period of your power is arrived. Your threats cannot move me to do an act of wickedness; but they confirm me in a determination of not creating you a companion in vice. Shall I, in cool blood, set loose upon the earth a dæmon whose delight is in death and wretchedness? Begone! I am firm, and your words will only exasperate my rage."

The sentence you are solving goes here.

"Devil, cease; and do not poison the air with these sounds of malice. I have declared my resolution to you, and I am no coward to bend beneath words. Leave me; I am inexorable."

Text from the Project Gutenberg edition, which is in the public domain in the United States.
