The Hanging Rock Mystery

The Hanging Rock Mystery

This article relates to Picnic at Hanging Rock

When Joan Lindsay's novel Picnic at Hanging Rock was first released, readers had a pressing question: was it based on a true story? The book's prologue suggests that it might be: "Whether Picnic at Hanging Rock is fact or fiction, my readers must decide for themselves. As the fateful picnic took place in the year nineteen hundred, and all the characters who appear in this book are long since dead, it hardly seems important." Adding fuel to the suggestion that the story might be a true one is that the author really did attend a girls' boarding school (as a day student) in Victoria, Australia, in the early twentieth century. And Hanging Rock is a real landmark in the area.

Asked in a 1974 interview about the story's apparent basis in reality, the author remained vague: "Well, it was written as a mystery and it remains a mystery. If you can draw your own conclusions, that's fine, but I don't think that it matters."

Adding to the intrigue surrounding the book is its ambiguous ending. For many readers, the fact that some questions are left unanswered added credence to the suggestion that the story is a true one. However, the ending of the published book is quite different from the original draft. The first ending resolved the mystery more neatly, but was removed before publication at the suggestion of Joan Lindsay's editor, Sandra Forbes. After Lindsay's death, at the author's request, the original ending was published as a standalone book called The Secret of Hanging Rock.

Some smaller details in the story appear to be fictional. For instance, readers have pointed out that though the book begins on Saturday, February 14, 1900, Valentine's Day actually fell on a Wednesday that year. The author, who had a longstanding interest in mysticism, has also said that the plot came to her in the form of a lucid dream.

In an interesting twist, Joan Lindsay's biographer Janelle McCulloch said in a 2017 interview that she'd found evidence suggesting the book was based on a true story. She discovered that two lines had been deleted from the forward prior to publication: "For the author, who knew Mount Macedonia and the Hanging Rock very well, the story is entirely true." To McCulloch, it seemed bizarre for Lindsay to write these words if the story was pure fiction. McCulloch tracked down a 100-year-old former student of the school Lindsay attended, who told her: "We all knew about the girls who disappeared, but none of us really knew the details."

Turning to online archives, McCulloch found a local police gazette from the late 19th century about missing girls whose age and descriptions matched the novel's characters. Though the disappearance happened before Lindsay was born, her great-grandfather had once been the area's police magistrate.

Joan Lindsay died in 1984, and the truth to the Hanging Rock mystery along with her. But whether it's inspired by real events or not, the story has endured because it's such a compelling one. The profound impact it has had on its readers over the years is inarguably real.
