Three women have been found dead in East Anglia. The police deny a connection. TV news reporter Frankie smells a story... Ava knows that the threat is real. She's been kidnapped by someone claiming to be the killer: a stranger who seems to know everything about her. As Frankie follows the case, she enters a terrifying online world where men's rage against women may be turning murderous - and where her persistence might just make her a target. And Ava must struggle not only to stay alive... but to stay sane. From journalist Elodie Harper, THE DEATH KNOCK is a compelling story of the worst that man can do and the hunt for the truth - at all costs.
