The Bungalow Mystery is the third volume in the Nancy Drew Mystery Stories series written under the pseudonym Carolyn Keene. It was the last of three books in the "breeder set" trilogy, released in 1930, to test-market the series. It was the final volume edited by Edward Stratemeyer before his death. His daughter, Harriet Stratemeyer Adams, extensively revised the novel in 1960. Source: Wikipedia (en)
