No.1 international bestselling author Tara Moss returns with an immersive post-war mystery as glamorous investigator Billie Walker follows a trail of secrets to Italy's sun-drenched Neapolitan coast.

Naples, 1943. Deep within a secret network of underground tunnels, a woman takes shelter from a wartime air raid and prays her husband will return safely.

Pacific Ocean, 1907. A young woman embarks on a lonely journey to begin a new life far from home.

Sydney, 1948. Billie Walker, recently returned from a stint as a wartime investigative journalist, has reopened her father's private inquiry office. Billie is cleaning out old filing cabinets when she uncovers a dusty box whose contents just might upend everything Billie thought she knew about her late, beloved father.

Soon Billie is on the scent, uncovering the secrets of her family's past, travelling aboard the first postwar luxury passenger ship from Sydney to Naples in search of answers. And as the trail leads her toward two women whose history is entwined with her own, she realises she is not the only one at risk. Billie's father had an enemy - one who may now be stalking Billie around the world - and the closer Billie gets to the truth, the more danger she finds herself in.
