Celebrating her 45th birthday at her local pub, podcaster Alix Summer crosses
paths with an unassuming woman called Josie Fair. Josie is also celebrating her
45th. A few days later, they bump into each other again, this time outside
Alix's children's school. Josie says she thinks she would be an interesting
subject for Alix's podcast. She is, she tells Alix, on the cusp of great changes
in her life. Alix agrees to a trial interview and indeed, Josie's life appears
to be strange and complicated. Alix finds her unsettling but can't quite resist
the temptation to keep digging. Slowly Alix starts to realise that Josie has
been hiding some very dark secrets, and before she knows it Josie has cajoled
her way into Alix's life - and into her home. Soon Alix begins to wonder who is
Josie Fair really? And what has she done?
