The title of this story can be read in more than one way. Oliva's father-in-law tells her what seems to be a confession, but since he has Alzheimers Disease, is what he's saying true or just his mind getting muddled. As Olivia tries to investigate based on just an off-hand comment, she starts to wonder who in her family is telling the truth.
This is a great story that's hard to put in a genre, it's not a psychological thriller, it's not a police procedural and it's not really a murder mystery, although it seems there might have been a murder and there's certainly mystery around it. It's more about Olivia and her convictions and about family and about lies. Should you tell them? Should you keep secrets?
I enjoyed reading this although I did want to knock the characters' heads together at times.
