Query: Training Day

I am on an Ian Rankin kick. And this one is pretty good. Rebus is off to training in this one and comes across cold cases that he is able to help solve. Clarke is kind of on her own while he's away, but they eventually come together with their excellent one-two punch. Enjoyed it. Not my favorite by this author, but I enjoyed it.
