“Harriet the Spy” follows the outspoken and perpetually curious 11-year-old Harriet M. Welsch. More than anything, Harriet wants to be a writer, and in order to be a good writer, she’ll need to know everything. And to know everything means she’ll need to spy … on everyone! This season, follow Harriet as she navigates letting go, growing up, and celebrating the gift of today.
