Perfectly competent murder mystery. If you like the rest of Rendell's Wexford series, you'll like this one. The lackluster rating is from a few ticks that I'm finding more than a little bit annoying:
a) Rendell never gets over her really really white perspective on growing societal diversity, especially cultural mixing and immigration. She's overall most of the time, I think, intending to be good about it, in a didactic way, but pretty much all her core character remain, book after book, incredibly self-conscious and insecure about the whole thing. They constantly say things like "maybe this is not the politically correct way of saying this" or silently exoticize a POC's physical attributes while being aware this is something they're not "supposed" to do. Wexford and his most senior colleague (and other character), and therefore obviously Rendell, are aware that this is a form of racism, and don't shy away using the word, but couldn't they by now have found a way of dealing with it? Just figure out how to appropriately refer to different kinds of people and for god's sake rein in your tendency to remark on every immigrant's skin colour and accent, especially since you're aware it's not an ok thing to do. As a way of giving life to the occasional character it would be fine, but nearly everyone all the time gets annoying. (She appears to be somewhat more relaxed about gender and sexual orientation, though the gay man in this story is so overwrought it strains credibility. I don't know any gay many these days who'd refer to himself as "homosexual", and no, it's not a technical or scientific term, these days.)
b) We're supposed to like Wexford, and in many ways that's ok. He's smart, kind and has good values. But he also handles a lot of situations very badly, and there's nothing in the story that makes me think we should disapprove. I am particularly thinking of the scene where a young adult gets told about their family background. There would have been several ways of handling it better, including the way the young person asked for, which the other party ALSO wanted. But somehow this doesn't happen and when things go south all the bad effects are attributed to the young person. I could also do with the weird and extraneous musings about how overweight women are are unattractive to Wexford. Wexford isn't my favorite police detective hero.
