I loved the clever premise of this novel. Edgar Allan Poe enters the labyrinth beneath Paris to solve a murder with his own creation, Auguste Dupin, in 1849. Think Agatha Christie solves a murder with Hercule Poirot. The story was intriguing, and I also noted early on, took place just a few months before Edgar Allan Poe's death in October of 1849. I did get a bit surreal, but I should have expected it as the story delved into mesmerism and the spirit world. This is the third book in the series, which means I should now go back and read the first two.
