The babysitter and the man upstairs

The tale of the babysitter who receives an eerie phone call only to discover the call was placed from inside the home has been popular since the mid-20th century.
The story has yielded several films, including 'When a Stranger Calls' (1979) and its spin-offs.
The story is based on a real-life crime that took place in 1950 in Missouri, USA. A 13-year-old named Janett Christman was babysitting a three-year-old boy at his home when she was brutally raped and murdered by an intruder. Her case remains unsolved.
