This is another in the series of Tony Hill/Carol Jordan books, and I love those characters. In this one, there are a series of teenagers being killed, and the key seems to be their online presence. Jordan is dealing with a new boss who is keen on having her move away from her professional relationships with Hill, regardless of how fruitful it is, and Hill is discovering things from his past that are changing his view on himself and his place in the world.
I’ve found when reading slightly old books (this was published in 2009) that while the author is incorporating the internet into their story, it can be really clunky – just because progress in these areas has been so rapid. It didn’t bother me in this, though. I just enjoyed seeing the relationships play out and the cops doing their thing.
