Australian writer Emma Callander has been recruited to complete the final historical mystery in a series by celebrated author Iris Blackburn. It’s 1964, and Iris’s memory is fading. She’s certain that only Emma can do justice to her novel about a murder on the Isle of Skye. When Emma ventures to Scotland for research, she discovers it isn’t fiction at all, but rather a true crime unsolved for more than fifty years. It was 1904 when a couple’s suspicious drowning led to the disappearance of a mysterious young woman the locals called the Wild Girl. To this day the mystery is unforgettable, especially among the descendants of an aristocratic family who’ll do anything to keep their secrets buried. From the misty Highlands to a medieval castle, Emma and Tony Gordon, Iris’s handsome lawyer, work ever more closely to uncover them. But while Iris may be known for her fiendishly clever twists, there’s one not even Emma could have seen coming.
