After thirteen-year-old Agnes Fisher faints at school, her teacher, the young and still idealistic Amy Slade, is shocked to discover in the girl’s desk two stereoscopic photographs. One is of a dead baby in its cradle, and on the back Agnes has scrawled a terrible message. Worse, the other photograph is of Agnes in a pose captioned “What Mr. Newly Wed Really Wants.” When Agnes doesn’t show up at school the next day, her teacher takes the two photographs to the police. Murdoch, furious at the sexual exploitation of such a young girl, resolves to find the photographer – and to put him behind bars.
