At last we begin delving into the real world of Sherlock Holmes. Though the little crime incidents themselves are fictional, Pirie has made a genuine effort to create characters that are believable and included many facts about Dr Joseph Bell, the model for Holmes, and Doyle that make you believe what you are reading as truth!
It's written in an excellent web-like fashion, keeping you gripped with various different mysteries.
The world that is depicted can be compared to our modern world and both Doyle and Bell could just as easily be modern day characters. Indeed by merely removing the victorian surrounding, your horses and carriages, etc, and by replacing them with their modern day equavalents, like cars, etc, we have a modern mystery.
