Nancy Drew - The Silent Spy is a point-and-click puzzle game, developed by Her Interactive and serving as the 29th game in the long-running Nancy Drew video game series. Players take on the role of fictional detective, Nancy Drew, as she investigates the truth about her mother's apparent death in a car accident. It is a single-player adventure, which relies heavily on puzzles and memory games. The game also makes great use of audio, both in terms of atmospheric music and voice overs. With that being said, there have been few improvements to the visuals compared to earlier games in the series and some of the puzzles may be too complicated for some players, so a strategy guide may be required at certain points.
