WWII may be over, but journalist Billie Walker's search for a missing young man will plunge her right back into the danger and drama she thought she'd left behind in Europe. It's 1946, and though war correspondent Billie Walker is happy to finally be back home in glamorous Sydney, for her the heady postwar days are tarnished by the loss of her father and the disappearance of her husband, Jack. To make matters worse, newspapers are now sidelining her reporting talents to prioritise jobs for returning soldiers. Determined to take control of her future, she reopens her late father's private investigation agency, and, slowly, the women of Sydney come knocking. At first, Billie's work consists of tailing cheating husbands. But when a young man goes missing, Billie finds herself on a dangerous new trail that will lead her to the highest levels of Sydney society, and down into its underworld. As the risk mounts, Billie realises that there is much more than one man's life at stake. Though the war was won, it is far from over.
