Joan Lindsay's classic novel Picnic At Hanging Rock is a subtle blend of mysterious and sinister events set in a period of Australian social life drawn with loving nostalgia. The final chapter was removed at the request of her publishers, creating a mystery to which thousands have begged to know the solution. The missing chapter reveals what did happen to the schoolgirls who vanished from the Rock after a St Valentines Day picnic in 1900. With commentaries by John Taylor, Yvonne Rousseau and Mudrooroo.
