The Secret Keeper by Kate Morton

I didn't think the secrets in this novel were commensurate with the plot's concealment of them: the book spends a lot of time with an actress trying to uncover her mother's secret past from World War II--while she could have just asked her mother (who was ill, but able to talk, and as it turns out, finally willing to do so!). I thought the story and the mystery were intriguing--and I loved the historical aspects of the story--but the present-day frame just didn't excite or convince me.
