The Girls of Friendly Terrace (or Peggy Raymond's Success) - Harriet Lummis SMITH

Peggy Raymond and her friends, Amy, Priscilla and Ruth, encounter a new neighbour, Elaine, and her family. While Peggy, in her usual cheerful and practical manner, welcomes them into the neighbourhood of Friendly Terrace, a variety of mysteries slowly unfold about them and why they ended up moving there. (Harriet Lummis Smith later went on to write four sequels to Eleanor H. Porter's "Pollyanna" books.) (Summary by Daryl Wor)
