Even though this is book 3 of a series I picked it up and was able to enjoy it without any of the history of the characters. It is a serial killer thriller set in Jeddah Saudi Arabia and the hunt for the killer is interestingly played out against the cultural and religious expectations of the country. Thus a female forensics detective has to battle the authorities requirements that women are covered, do not mix with men, and have a subserviant role when clearly this is an exceptional woman investigator. The book deals with religion, exploitation of immigrants, the effect of adultery, the impossibility of divorce,womens role in the society, and the corruption of the system in a way that did not feel forced and only added to the tension of the police procedural. A very enjoyable page turner and I will look out for more of her books.
