A 240.36MB demo of Nancy Drew: Ransom of the Seven Ships (PC) is now available on FileShack, allowing you to sample a portion of what publisher Her Interactive refers to as "the 20th installment of the best-selling adventure game series."

As past data has shown, Her Interactive isn't joking about with the "best-selling" part. This time around, Nancy's attempt at a vacation is sidetracked when her friend Bess gets kidnapped. No word if the plot was, in Law & Order tradition, "ripped from the headlines."

The latest adventure of the cultural icon arrives at North American retailers on July 14, with Her Interactive also revealing that male counterparts The Hardy Boys will bring their rapscallion adventures to Nintendo DS on September 1, 2009.

"The first-ever Hardy Boys game for the Nintendo DS," The Hardy Boys: Treasure on the Tracks is being published by Sega. The timing seems to indicate that Nintendo-owning fans of the brotherly duo will receive a double dose of adventure in September, as that month will also see JoWooD's Wii premiere of The Hardy Boys in The Hidden Theft.
