Every good detective knows that in order to successfully investigate a case, a certain level of impassivity needs to be maintained — you get too invested in the case, and mistakes get made. Investigating your own mother's death would seem to be out of the question entirely, but how can Nancy resist the chance to learn the truth about her own mother's tragic demise? Nearly a decade has passed since Kate Drew traveled to Scotland to neutralize a biochemical weapon. It seemed so unfair that she should be able to successfully complete such a dangerous task, just to die in a car accident, but maybe that's not what really happened. Maybe there's another story — and when the echoes of a similar plot reverberate, it's up to you as detective Nancy Drew to expose the sleeper cell and learn the truth once and for all. Set off for the hills of Scotland in Nancy Drew: The Silent Spy as you take on her most personal case yet. Armed with an arsenal of cutting-edge spy gadgetry, you must use your wits and gather your courage to expose secret agents, thwart black operations, gather intelligence and find new leads. With each new clue that you find, you'll trigger vivid memories of Nancy's childhood, bringing you one step closer to learning what transpired during Kate Drew's final days. With new twists unfolding at every turn and characters changing their motives as the investigation unfolds, you'll need sharply honed spying skills to get you through. Start in Amateur level and work your way up to Master Sleuth — no matter what, only you can defuse this toxic plot.
