This is a good gripping crime thriller that starts with a skeleton being found on the roof of a derelict building and leads the investigation to London and Croatia and a past filled with horror and revenge. The story develops well with a slow build to start with before escalating as the strands begin to cross and weave together. In between the main story there is the background to how Maggie and Mitja met and how their relationship developed, which seems disjointed to start but reveals intriguing facts and hints that build up the background and leads to the big reveal at the end.
