Games based on the the children's mystery fiction heroine, Nancy Drew.
Nancy Drew "was created by Edward Stratemeyer, founder of the Stratemeyer Syndicate book packaging firm. The character first appeared in 1930. The books have been ghostwritten by a number of authors and are published under the collective pseudonym Carolyn Keene. Over the decades the character has evolved in response to changes in USA culture and tastes. ... In the 1980s a new series was created, The Nancy Drew Files, which featured an older and more professional Nancy as well as romantic plots. In 2004 the original Nancy Drew Mystery Stories series, begun in 1930, was ended and a new series, Girl Detective, was launched, with an updated version of the character who drives a hybrid electric vehicle and uses a cell phone."
