Nancy Drew®: Mystery of the Seven Keys™

Mystery of the Seven Keys is the 34th installment of the Nancy Drew point-and-click adventure game series by HeR Interactive. The game takes on the first-person view of Nancy Drew and must solve the mystery by questioning suspects, solving puzzles, and discovering clues. The game has two levels of difficulty: Amateur sleuth and Master sleuth. The Amateur sleuth's difficulty offers a task list and gives the possibility of hints in-game, compared to the Master sleuth option which has no task list, no hints, and more challenging puzzles. This is the first game of the series that offers a dual navigation system: point-and-click and free-roam. It has an ESRB rating of E10+ for moments of mild violence. It is loosely based on the 83rd novel from the Nancy Drew Files series, Diamond Deceit.
