There is so much to like about this novel, not just that it is by a South Australian author, or that it is right in the time frame of my own life.

The action begins in 1979 with the disappearance of a 4 month old baby while her parents are at a dinner party in a neighbouring house. 40 years later 'The Callaghan Baby Podcast' is investigating what is now a forty-year-old cold case, bringing together investigative evidence from when the disappearance happened, police reports, a coronial investigation, interviews with suspects, family and neighbours both then and now. The author combines that with other voices, particularly that of Billie, the adult daughter of baby Megan's sister.

This made the structure of the novel very complex, and quite challenging for the reader, but a staggering achievement. So much of the book rang true for me.

The family is marking the anniversary of Megan's disappearance with a family gathering when there is a knock at the door: a stranger is standing on the doorstep.

Little by little, elements of the mystery are revealed and the reader is asked to assess evidence.

Highly recommended. ( )
