State prosecutor Chastity Riley runs off to Glasgow. For one, there is that letter, written by a lawyer, that lures her to the birthplace of her great-great-grandfather. And secondly, her life in Hamburg has arrived at a sad impasse. In the rough, Scottish city she meets Tom, who knows the key that unlocks the Rileys' family secret. She never dared confront the painful truths about herself, but some whisky and a few ghosts help her to do just that. As an entire street burns in Hamburg, a few estate agents shoot off each other's faces and Inspector Stepanovic refuses to work, Riley battles the ghosts of her past in Glasgow. . . and the lost souls that could be her future.
