Andy, I too am glad that you liked THE MYSTERY OF EDWIN DROOD.
Since I too have read the book, I'm currently re-reading it in an interesting way. I'm reading a book called THE D CASE OR THE TRUTH ABOUT THE MYSTERY OF EDWIN DROOD by Charles Dickens, Carlo Fruttero and Franco Lucentine. It's a fun way to read the original novel by Dickens since this book reprints "The Mystery of Edwin Drood" in its unfinished entirety and, at the end of each chapter, famous detectives of fiction (Sherlock Holmes, Poirot, Father Brown and others) discuss the "evidence" with one another and try to solve the mystery.
