High Quality Content by WIKIPEDIA articles! Shadow at the Water`s Edge is the 23rd installment in the point-and-click Nancy Drew adventure game series by Her Interactive. It is preceded by Trail of the Twister and followed by The Captive Curse. The game runs on Windows XP and Windows Vista. It is also the third game of the series that can run on Mac OS X. In the game, the player assumes the role of American teenage detective Nancy Drew, using puzzles and interrogation of non-playable characters to solve a mystery. There are two levels of gameplay, Junior and Senior detective modes, each offering a different difficulty level of puzzles and hints. (Neither of these changes affect the actual plot of the game.) Since it contains scenes with mild violence and peril, the game is rated E for everyone 10 and up.
