A string of fatal arson attacks have broken out in San Francisco. The targets have one thing in common – they are all rich, successful, married couples. With four couples dead, Lindsay is determined to stop the killings and trace the murderer. Lindsay is also on the case of Michael Campion, people’s hero and popular governor’s son who publicly battled against a rare and debilitating heart condition. When he vanished without trace one evening, the search for him hit the headlines daily. But the trail went cold very quickly. Now there is a devastating new lead – but what is the link between the Campion case and the arson attacks? Lindsay and her fellow Women’s Murder Club members are in a race to find the suspects and stop the killers.
