Tom Thorne may be a retired detective, but the author clearly cannot let go of the character, so once again he pops up in an unofficial capacity, becoming central to the story. In this case, matters start with the murder of Detective Inspector Nicola Tanner’s partner, in what seems to have been an attack meant to silence Tanner, working on several ‘honor’ killings. Tanner is taken out of the firing line, but she is not convinced anyone will do enough to find the killer, and she persuades Thorne to get involved. From this point on, the roller coaster ride begins.
Thorne and Tanner are comprehensive and believable characters, and their interaction and involvement are key to the success of the novel. However, the supporting cast are not always mere fillers, and the overall impression is of a well constructed, realistic, gritty crime novel. In other words, a damn fine read.
The honor killing part is handled without sensationalizing this difficult cultural issue. I did, however, think there was a degree of political correctness on show with the attempt at evenhandedly apportioning the sources of such crimes across multiple religions. That was the only very minor criticism I would make.
It’s best to read the Thorne books in order, but if you prefer just to dive in here, you will not lessen the enjoyment too much. It is a solid standalone tale.
