Secrets Can Kill is the first of many installments in the Nancy Drew point-and-click adventure game series by Her Interactive. It was officially discontinued in 2010. The game had an ESRB rating of E for moments of mild violence and peril. Players took on the first-person view of fictional amateur sleuth Nancy Drew and solved the mystery through interrogation of suspects, solving puzzles, and discovering clues. The game is animated in 3D, but unlike later games, the characters are 2D.
