Sherlock Holmes and the Christmas Demon

This was an included listen on audible, so I gave it a go for a holiday mystery read. 
Eve Allerthorpe approaches and attempts to hire Sherlock to help her with a mysterious figure, the Black Thurrick, that has been haunting her. It's kind of a folklore holiday figure like Krampus, which is not the type of thing Sherlock does, but this time he agrees. Mayhem, mystery, ghosts, gambling, subterfuge, and murder follow. 
I felt like this was a pretty good Holmes entry à la Arthur Conan Doyle's style. Holmes uses deduction, as well as a manner of deception to get to the heart of the matter. Watson is elementary as usual, but I do enjoy his narration of the story as a whole. He is Holmes' Captain Hastings of course, so it makes sense that I like him. (I know Holmes was first...). 
Personally a 4/5* for me, not very Christmasy, but the mystery was fun.
