Although DCI Alan Banks and DI Annie Cabbot are no longer a couple, they're still tied together through their work, even when Annie is out on loan to another area. Annie's challenge is the murder of a quadriplegic in a wheelchair. Banks is faced with the brutal rape and murder of a teenager. Normally these cases wouldn't overlap, based on type of crime and divergent locations; however, Robinson is a master at intertwining story lines, so even without the jacket copy, the reader knows to pay attention.
I particularly like the way Robinson uses different formats in his writing. No one can ever accuse him of writing the same book over and over. This one had me finding excuses to eat alone in order to read!
