Big Spoiler Alert!
I've just finished this. I wasn't sure if the twist at the end was that O'Hara (the actor she has an affair with) turned out to be her father. It really looked to me that he was, but I've just been doing a search, and I can't see this mentioned anywhere. Has anyone else read this, and if so, do you also think that O'Hara was Stella's father?
