Harriet Adams continued to oversee the series, after switching publishers to Simon & Schuster, until her death in 1982. After her death, Adams' protégés, Nancy Axelrad and Lilo Wuenn, and her three children, oversaw production of the Nancy Drew books and other Stratemeyer Syndicate series. In 1985, the five sold the Syndicate and all rights to Simon & Schuster. Simon & Schuster turned to book packager Mega-Books for new writers. These books continued to have the characters solve mysteries in the present day, while still containing the same basic formula and style of the books during the Syndicate.
