Louise Fitzhugh

The story about eleven-year old Harriet, who is a spy, plans to be a writer, and keeps a secret notebook filled with thoughts and notes on her school mates and people she observes on her after-school "spy route." However, when her classmates find and read her notebook, their anger and retaliation, and Harriet's unexpected responses, explode in a hilarious and often touching manner.

A young girl is embarassed when her journal is found and read by a schoolmate because of her unkind observations, even about her own friends. After she is ostracized, she first tries to get revenge and then works hard to make amends with her friends and fellow students.
