Query: Routine

After all the fanfare leading up to the appearance of "A Question of Blood" in the US, I found this novel vastly overrated. There is nothing new here. Inspector Rebus is a loner cop who Doesn't Play by the Rules. His sidekick, Siobhan Clarke, is slightly more interesting, and of course she Doesn't Play by the Rules either. The crime is not hard to solve and the book is easy to put down. The plot lacks urgency. Disappointing.
