Adapted from the "Nancy Drew" novel, "The Password to Larkspur Lane," first published in 1933. The original author of the novel was Walter Karig (using the Stratemayer Syndicate house pseudonym, "Carolyn Keene"). In the "Nancy Drew" books, Nancy's boyfriend is named Ned Nickerson. For the 1938-39 movie series, his name was changed to Ted Nickerson (played by Frankie Thomas).
