Conviction by Denise Mina

A true-crime podcast sets a housewife’s present life on a collision course with her secret past.

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, Anna returns to the podcast. Other people’s problems are much better than one’s own–a sunken yacht, a murdered family, a hint of international conspiracy, 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. The devils of her past are awakened–and in hot pursuit. Convinced she has no other options, she goes on the run, and in pursuit of the truth, with a washed-up musician at her side and the podcast as her guide.
