An old English estate and a decades-old mystery give this slow-burner of a book its atmosphere, but Morton's sharp storytelling keeps you trying to work out the puzzle from start to finish. Sixteen-year-old Alice's family is torn apart when her baby brother disappears during a midsummer's eve garden party. He is never found, and the house is abandoned. When a wandering detective discovers it years later, she unearths the old mystery and secrets that had been long forgotten.
