She may have debuted 70 years ago, but that doesn’t mean the original girl sleuth can’t translate into cyberspace. At this site (administered by San Francisco-based Newfront Productions, Inc.), fans can go beyond the traditional paperbacks and read up-to-date, interactive mysteries (”Help Nancy! What should she do next?”) where they can decide whether to put together a suspect list or investigate the scene of the crime. It’s also a tribute to all things Nancy, filled with trivia (her ”favorite color is blue — the traditional color for boys”) and loving essays assessing how the heroine has evolved through the decades. ”Nancy Drew on Campus: Love Online,” anyone?
