I find it remarkable that in both of the Atkinson novels I have read, this and Behind the Scenes at the Museum, Atkinson heavily invests in the complications -- the desperate affection and rivalry -- of sisterly relationships. And, in each novel one sister has had a hand in a death and an other sister takes the blame.
I would so very much like to read an interview with an Atkinson sibling, but it appears that I cannot as wee bit of internet research seems to show that she is an only child, which really disrupts my theory of writing as PTSD therapy. I suppose that is a compliment to Atkinson, that she could concoct such complex relationship drawing not-at-all upon personal experience.
Behind the Scenes at the Museum has a complicated, and often confusing, pattern of narration; Case Histories does not. It reads easily and hooked me early on. The mysteries are well-crafted in that I thought I knew who did what to whom, but I was wrong. And once again I am struck by how well Atkinson writes the internal dialogue of the very young.
If I know you in real life and you want to borrow this, let me know lest I list it on bookmooch.
