Doctor Who: The Vampire of Paris (The Darksmith Legacy Book 5)

The Vampires of Paris has been the most interesting Darksmith Legacy book so far. While all the books have had a mystery for the Doctor to solve, I feel that this one has been much more mysterious than the others. Even though it wasn't longer -they've all had a similar amount of pages- it did feel longer. Also, you can read it like a short murder mystery, which may have added to my enjoyment of this book.
We don't learn much about the general plot, but a few secrets are discovered. Not many and what we learn is not particularly relevant, but it's another piece in the puzzle of the Darksmiths and the Crystal.
