The Bungalow Mystery

Nancy Drew is a fictional character, a sleuth in an American mystery series created by publisher Edward Stratemeyer as the female counterpart to his Hardy Boys series. The character first appeared in 1930. The books are ghostwritten by a number of authors and published under the collective pseudonym Carolyn Keene.
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.
