Who is out to destroy Carmel O'Sullivan and her sister Tess, top call-girls in Rita Saunders' gentlemen's club? Who will be next? When Tess is murdered and younger sister Maxine is among the passengers on the ill-fated Air New Zealand flight to Mt Erebus, Carmel feels God has turned away from her family. Secrets emerge as the police investigate. The spotlight shifts incessantly. Hungarian immigrant Istvan Ziegler loves Carmel, offering her the safety and respectability she craves, but he has to compete with Rita for Carmel's affection and commitment. "The Final Call" is a gripping family saga, deftly showing how society's attitudes to prostitution, gays, lesbians and independent women received a good shake-up in 1970s Auckland. It is Jen Shieff's third book, a standalone sequel to "The Gentlemen's Club" (2015) and "The Vanishing Act" (2018), both finalists for a Ngaio Marsh Award.
