In the vein of some of the re-writings of Sherlock Holmes this is Sherlock as a bit of an idiot, saved by the cleverness of Dr Watson. This is a set of stories, rather than just one, detailing Watson's introduction to the world that Holmes inhabits (and honestly it's done better in the Lord Darcy series). There's a vampire, Inspector Vladislav Lestrange and an Ogre and a variety of other characters that I neither cared about or really remember.
It's not terrible but I have absolutely no inclination to read further in this series, it wasn't enough of any of my catnip to really interest and too much of a parody to make me happy with it. It occasionally came across as trying too hard.
The reader, Robert Garson, did quite a good job of reading it.
