Going to bring this back from the dead.
Currently reading, (finished it anyway,)
Sherlock Holmes vs Dracula. (also known as "The adventure of the sanguinary count" ) by Loren D. Estleman.
Awesome book, I must say. I mean, the whole Idea is so ridiculous, but yet- So ridiculous that it manages to work, and come off as awesome.
I'd recommend it to Sherlock Holmes AND Dracula fans.
