I was surprised by this book. I mean I knew overall what the book would be about, but I wasn' prepared for the intertwining mystery that evolved. I think that Graham Moore dd an excellent job with the two separate storylines. Each chapter change when we would incariably change time settings and characters I would get sucked right back in to that storyline as though I had skipped every other chapter and just read the particular time period whether it was 1900's or 2010. Now that I mention it, that may be aninteresting way to go back and reread this story in the future.How would that add or detract from the story as a whole. The reader would then be able to see how each story sort of feeds off the other. How the 2010 storyline wouldn't be as exciting or possible without the events of 1900 going on at the same time in the novel. 
 The book truly makes me want to go back and read more Sherlock Holmes stories. You can really tell that Graham Moore has a passion for Sherlock Holmes. But the ending is bittesweet. It goes back to that old saying that something you think you want so badly in life is never what you expect it to be once you actually attain it. Some things are better left in mystery I guess.
