A novel by Kate Morton which I found to be uneven but intriguing nevertheless. Laurel Nicholson is hiding from her sisters in her childhood treehouse during a family birthday party when she sees a stranger coming onto their farm. She watches as he and her mother speak... and then witnesses a crime that calls into question all she thought she knew about her loving, imaginative, near-perfect mother, Dorothy. Fifty years later, Laurel is a successful actress in London. The family is gathering at the old farmhouse for her mother's ninetieth birthday and Laurel decides it's time to find the answers for that crime that still haunts her; answers buried in her mother's past from pre-WWII England through the blitz and the unlikely friends she made then, to the 1960s and beyond.
