This was thoroughly enjoyable. This book describes the making of the BBC series Sherlock from Season 1 through 3. It includes photographs of the locations used in filming, sets, props, the actors and concept art. It also includes parts of some the scripts before they were changed. It was quite interesting reading about all the work that goes into making a single episode of Sherlock. If you're a fan of Sherlock, I suggest reading this book; it gives you a look at the creative process.
