I've been a fan of Mercedes Lackey for several decades but it's possible I'm finally suffering from diminishing returns. A Scandal in Battersea is the twelfth Elemental Masters book and it felt a bit rote to me in some ways. The bad guy was one of the most horrific I've come across, but the plot overall seemed very predictable and not very interesting. I do love this iteration of Sherlock Holmes and the Watsons, and the central characters of Nan and Sarah are still sweet, but there was nothing new to add to their story in this book. There was a magical threat to London and they thwarted it. I even lost track of the book in several places when I fell asleep listening to it or got distracted by something, which doesn't often happen, and it didn't feel as if I had missed much. Hey ho.
