Killer Profile

I also found that the description of the agents was a bit too detailed. Assuming that the main readers of these tie-in novels are fans of the show, describing what the main characters are wearing more than once is unnecessary. We can all imagine them and it didn't add anything to the plot.
The case was ok, but the identity of the killer is predictable if you've read a couple of murder mysteries. Still, it was interesting to see BAU follow the clues.
In case there are people worried about possible spoilers, the book is set shortly after Rossi joins the team, but other than Rossi being there and a brief mention of Gideon, there aren't any other references to the show.
