The day Anna McDonald's quiet, respectable life explodes starts off like all the days before: packing up the kids for school, making breakfast, listening to yet another true-crime podcast. Then her husband comes downstairs with an announcement, and Anna is suddenly, shockingly alone. Reeling and desperate for distraction, she returns to the podcast. Other people's problems are much better than one's own. But this case actually is Anna's problem. She knows one of the victims from an earlier life, a life she's taken great pains to leave behind. And she is convinced that she knows what really happened. Then an unexpected visitor arrives on her front stoop, a meddling neighbor intervenes, and life as Anna knows it is well and truly over.
