Native son 94-140

"And now that he had kill Mary he felt a lessening of tension in his muscles; he had shed an invisible burden he had long carried." (114)

The invincible burden in Bigger’s life is being suppressed by the white man, who Bigger acknowledges to be a natural force. By killing Mary, Bigger does not attempt to resist that force, but simply side step it redirect it. Bigger attempts to exploit the Dalton’s belief that because Bigger is black he could not have possibly accomplished a murder (specifically one of their daughter). Bigger’s plan to focus the blame of Mary’s murder on Jan is his way of redirecting the force right back at the white people. Bigger breaks their laws and has them pay for it.

Will Mr. Dalton suspect Bigger of murdering Mary?
Will Peggy put two and two together and learn that Bigger killed Mary?
