More Sherlock!

Hi,

I've read the original stories but can anyone recommend any non-Conan Doyle Holmes spin-off books. The other day I came across "Mycroft Holmes and the Adventure of the Silver Birches" by crime novelist David Dickinson, and loved it (short story was written with spirit, wit and intelligence of original stories). The publisher, Endeavourpress.com, seems to be publishing other Holmes related titles. http://www.amazon.com/Mycroft-Holmes...5606091&sr=8-2

Does anyone know of any other new e-books or books out on Sherlock though, apart from the new Horowitz one?

Thanks.
