What is wrong with Elizabeth's dining room table?
In the help

~Hi hope this helps

Miss Hilly notices an “L shaped crack” in Miss Leefolt’s dining room table. This is one of two of the largest clues which signify the fact that “Help” (the book written within “The Help”) was set in Jackson, Mississippi. The “L shaped crack” in Miss Leefolt’s dining room table was referenced in “Help” and through analyzation would prove that the book in fact included Elizabeth.

the whisper is the answer, hope this : )
