Not the strongest in the series (and a standalone that deals with Tobias Winter of the German magical police) about a murder in the German wine making town of Trier. Not bad either though, I just prefer Peter Grant. Winter is convincingly written, he's just not my kind of character. Aaronovitch is obviously a little into Roman Stuff, which, okay. Not by cup of tea either. But interesting case and I liked Vanessa.
