The spy route
Harriet lives on the Upper East Side of Manhattan. Every day after school, she follows a “spy route,” watching people through windows and writing notes: a lonely rich woman, a grocer's family, a man who builds birdcages. Her nanny, Ole Golly, encourages her to see the world and to write the truth.
Ole Golly leaves
Ole Golly falls in love and leaves to get married. Harriet is heartbroken. She feels alone, because her busy parents do not pay much attention. She keeps writing in her notebook, but she misses Ole Golly's wisdom.
The notebook
At school, Harriet's classmates find her notebook and read it. She has written harsh things about everyone, including her friends Sport and Janie. Her classmates are hurt and angry. They form the “Spy Catcher Club” and refuse to talk to her. They play mean tricks on her.
Hard times
Harriet feels lonely and angry. She acts out at school and at home. Her parents take her to a psychiatrist. She stops writing for a while. She realizes she does not know how to fix things. She writes cruel notes for revenge, which only makes things worse.
Making amends
Ole Golly writes Harriet a letter, telling her that sometimes she must lie a little to be kind and apologize to her friends, but she should keep writing the truth for herself.
