A fast moving plot, that starts innocuously with a widow inheriting her husband's business, but which proceeds to take us on a journey of poisoning, madness and megalomania in true gothic style. I loved this book. The characters are well-drawn, the plot twists and turns, and the descriptions of places like laboratories, the madhouse and the deadhouse are so realistic as to be tangible. Quite a short novel as well - only 300 or so pages, but quite possibly the most exciting 300 pages I have ever read! Incidentally, the Jezebel's Daughter referred to in the title has quite a minor role in the story. She is really merely a curb on her mother's excesses. A brilliant read!
