This is one of the best mysteries I read in a long time. It was advertised to me as a cross between Sherlock Holmes and Doctor Who and I was sold. I do believe fans of both will greatly enjoy it. The story was interesting, and all the characters were diverse and clever. I do believe that word best describes the book. It is clever; perhaps not openly funny or full of shocking twists, but it came together so that all the parts lined up so perfectly together, the reader cannot help but be swept along for the ride. I highly recommend this to Whovians, and mystery lovers everywhere. The ending leaves the reader satisfied, but excited for more.
