Last I read a Rennie Airth book was back in 2006, and then I was in such a mindset that I liked it. I am in no such mindset now, instead the formula bores me. All these serial killer books are always written in the same way, I've long since stopped feeling any suspense. Airth isn't great at producing characters with personality either, it's more like he only tells us that they have personality (like the producers of Doctor Who, Torchwood and Sherlock do, they turn to the camera and say, hey, these people care about each other, ok? now we shall proceed with a television production that never makes you feel it but that's ok because we're after telling you sure). You can see Airth's "this is personality" tricks a mile off. Anyway, serial killer, WWII, rations, snow, bombs. There you go.
