Natural Causes - James  Oswald

DI Tony McLean investigates a series of murders in Edinburgh, Scotland and confronts an ancient evil. He must find a way to put a stop to it and bring killers to justice.

I found this book as a free download for my Kindle and liked it so much I bought the second in the series. Although there's a paranormal element, it's neatly and subtly knitted into the plot. The first chapter is very graphic, but the rest of the book is a pretty straight forward police procedural. The characters are likeable, well-rounded and easy to relate to. I love the setting of Edinburgh, and I think Grumpy Bob is my favorite character name EVER.

I thoroughly enjoyed the book and look forward to more in this series, it's a great read on a dreary, grey day.
