" While this was a good book, this series is getting progressively worse (only word I can think to use although a little harsh) rather than better. THe set up was good, but the main bulk of the story fell flat for me, and I can't really remember the ending which doesn't code well. The characters are still wonderfully vivid, and their relationships are developing, but the plot was again a little meandering. I gave the first book five stars as I loved it and thought it was so original. This book is original, but the love was not there this time. I hope Aaronovitch isn't falling into the trap of getting published asap, rather than taking time over his work - which it was clear he did for the first book. The other two feel a bit of mish-mash. Will still read the next in the series as I like his style of writing and am really getting to love his characters. "
