At first this book may appear to be a simple murder mystery but rather than set in the usual Victorian or Edwardian England, it is set on a world other than ours, in the land of Idriss. Vidar, our anti-hero, has inherited a job after his much beloved predecessor's murder. He works to solve the mystery, and his investigations take him outside the walled city where he not only sheds light on his future, but his past. In the city, Rhiannon is also investigating the same murder, as well as subsequent ones by the same culprit. Her life, quite literally, depends on it. As I said earlier, this book is more than just a murder mystery set in a fantasy environment, because of the other themes it explores, such as love, betrayal, religion, and friendship. The world and its inhabitants are exquisitely detailed and I found myself wishing the book was bigger, or there was a sequel, as there is still so much left to explore.
