Nancy Drew and the Hidden Staircase (Film) (Paperback)

High Quality Content by WIKIPEDIA articles! The elderly Turnbull sisters want to donate their mansion for a children's hospital. However, their father's will states that at least one of them has to stay in the house every night for twenty years before they can inherit the estate; there are two weeks left to go. Then some strange things start occurring. A stranger forces his way past Nancy Drew (Bonita Granville) and brazenly searches the Drew house for related affidavits her lawyer father Carson (John Litel) has obtained. Then, the Turnbulls' chauffeur Phillips (Don Rowan) dies, though it is uncertain if it was a murder or a suicide. The frightened old ladies consider leaving their home. When Nancy recognizes the dead man as the trespasser, she begins investigating, dragging her boyfriend Ted Nickerson (Frankie Thomas) into one predicament after another, eventually getting him fired and jailed.
