Enjoyable. I've read Katia Lief in the past and think this is probably her best novel. The plot's lightweight but; there's a lot going on and the constant movement keeps the story ticking along nicely. The 12th Victim is incredibly easy to read, finished the book in a couple of days, and it's one of those novels you can dip in and out of without losing track of the plot. This is a basic police procedural with lots of investigation, bodies all over the place, and the typical cat and mouse chase which seems to ensue in every Katia Lief novel. The character of "The Working Girl Killer" isn't too real, I struggled to believe in him, and there's no real darkness or violence considering the subject matter. Very typical of this genre, nothing special, and it's a case with Katia Lief that if you've read one of her novels you're not going to be surprised by any of the others, they do follow a tried and tested format. The 12th Victim is a well written and entertaining read though never challenging.
