Magical. Horowitz has captured Watson's voice so well, there was never a doubt in my mind that this was a Sherlock Holmes adventure. Applause and much respect, Mr Horowitz!
The story drags a bit in places as Watson is given to long bouts of navel-gazing, but the crime is intriguing, Holmes is mesmerizing, and London is seedy and full of gangsters.
The final scenes bother me because a) child abuse makes me lose my shit, and b) it spoils the more 'romantic' aspect of crime Arthur Conan Doyle managed to focus on. I don't remember a crime as horrific as child abuse and rape in the original stories. Maybe I need to re-read them.
Now that I think about it, I find it disturbing that murder, in Sherlock Holmes novels, never really bothered me. I do not wish to explore what this says about me.
Anyway, read this. If you're a Sherlock Holmes fan. And why wouldn't you be?
