Meaning of Single Stories in To Kill a Mockingbird

In To Kill a Mockingbird, by Harper Lee, there are many single stories told about Negroes.  For example, after Jem, Scout, and Dill broke into Mr. Radley's yard, a negro was blamed for breaking in.  This is portrayed on page 54, when the children have come back from the yard and the adults are standing together talking about what just happened.  When Jem asked what had happened, Miss Maudie said that a negro had broken into the yard, although nobody had seen him.  This is a single story about race because nobody had seen who had been in the yard, a negro was the scapegoat for the crime and it was automatically assumed it couldn't have been a Caucasian.  Another time in which a single story about race is portrayed occurred on page 45.  In this setting, Miss Maudie told Scout that the rumors about Boo Radley were made up by Negroes.  This shows a single story because nobody knows who started the rumors, but it all ended up being blamed on African american citizens anyways.  #scapegoatingisntright #freeboo #dontshoot
