Sydney, 1946. Though war correspondent Billie Walker is happy to finally be home, for her the heady postwar days are tarnished by the loss of her father and the disappearance in Europe of her husband, Jack. To make matters worse, now that the war is over, the newspapers are sidelining her reporting talents to prioritize jobs for returning soldiers. But Billie is a survivor and she's determined to take control of her own future. So she reopens her late father's business, a private investigation agency, and, slowly, the women of Sydney come knocking.

At first, Billie's bread and butter is tailing cheating husbands. Then, a young man, the son of European immigrants, goes missing, and Billie finds herself on a dangerous new trail that will lead up into the highest levels of Sydney society and down into its underworld. What is the young man's connection to an exclusive dance club and a high-class auction house? When the people Billie questions about the young man start to turn up dead, Billie is thrown into the path of Detective Inspector Hank Cooper. Will he take her seriously or will he just get in her way? As the danger mounts and Billie realizes that much more than one young man's life is at stake, it becomes clear that though the war was won, it is far from over.
