The 12th title in the Nancy Drew Mystery adventure game series, Secret of the Old Clock, is based on the very first Nancy Drew book and commemorates the 75th anniversary of Nancy Drew. It's 1930 and Nancy Drew is asked to visit Emily Crandall in Titusville, a girl whom Nancy knows only through a mutual friend. She and her mother had been counting on the generosity of their kindly but strange neighbor, Josiah Crowley, to leave them part of his estate to support the inn they own. But in his will, everything was left to Richard Topham, his ESP teacher. A contested will, a suffering girl, suspicious psychics – can Nancy solve the mystery before time runs out?
