Nancy Drew has solved a lot of mysteries in her unusually long day, but never with a lead as small as this. Fortunately, fans of the teen sleuth will soon discover that bigger isn't always better, as The Deadly Secret of Olde World Park is now shipping to North American retailers.

The first Nancy Drew adventure created exclusively for the Nintendo DS, Deadly Secret sees the spunky girl detective investigating the disappearance of billionaire industrialist Thaddeus Belmont. On the eve of opening Olde World, a lavish theme park featuring the world's greatest historical civilizations, Belmont is nowhere to be found, and it's up to none other than Nancy to piece together what's happened to him.

The new game is not related to Her Interactive's popular PC mystery series, but developed by Gorilla Systems specifically to capitalize on the unique DS features. Players will guide Nancy on screen over the course of 13 increasingly difficult chapters, and the system's touch screen will be used for conversation, accessing Nancy's clue journal and unlocking mini-games.
