That story, The Plague of St James Infirmary, was actually rather dull, going for the duelling magician style Mythos story that is only really borrowing the names rather than the tropes. But it's getting better. The one I've just finished, the titular story, has a very original take on a central Mythos theme.
There's a review on Amazon which gives slightly too much away
And the next story is called Necrophallus.
