Of all the characters in the book, I understood Liz’s father the least. I believe it was Liz’s decision to believe him or not. She had to come to terms with her parents’ selfish and unethical actions. It is easy to judge that he cared most about his reputation just as Liz’s mother cared for her interest over the life of Alice, even of Liz. Each secret required a subsequent secret that ultimately hurt them all.
I would like to think legal adoption when Liz was a baby would have solved a lot of problems. When Alice died, police should have been informed of accidental manslaughter. The Brigadier would have enough clout to carry the day. All the other events created by the secrets would have been avoided. In general, people create greater problems when they hide the truth.
