Picnic at Hanging Rock by Joan Lindsay
Joan Lindsay’s 1967 novel, Picnic at Hanging Rock describes a mystery so compelling that many people believe it really took place. In the story, set in Australia in 1900, a trio of schoolgirls and one of their teachers disappear during a Valentine’s Day outing to the ominously named Hanging Rock. The story inspired a 1975 film, a 2016 play, and a 2018 television adaptation. This classic horror tale ends as mysteriously as it begins, leaving fans of the story ample grounds for speculation.
