The test of any truly good pastiche is whether or not you find yourself still trailing doggedly behind Homes and Watson after the first 20 pages or so, as they wind their way through the foggy thoroughfares of old London town. I can say unequivically that with this you certainly do. Whilst some of the terms used are not those that Doyle would have used they are easily overlooked. If you are a fan then read it. You won't be disappointed.
