The character was conceived by Edward Stratemeyer, founder of the Stratemeyer Syndicate.
Stratemeyer had created the Hardy Boys series in 1926 (although the first volumes were not published until 1927), which had been such a success that he decided on a similar series for girls, featuring an amateur girl detective as the heroine.
After Adams's death, series production was overseen by Nancy Axelrad (who also wrote several volumes).
The rights to the character were sold in 1984, along with the Stratemeyer Syndicate itself, to Simon & Schuster.
All royalties went to the Syndicate, and all correspondence with the publisher was handled through a Syndicate office.
