Spoiler Alert!: The killer is never ''found'' or confirmed, rather. A little more than half way in and realizing that I questioned whether or not I actually wanted to finish the book, what with all of the build up of the murder and all. Plus there are a few other secrets hinted at and teased to the reader that are never revealed. Despite that ( and some other boring - to my taste -general business jargon of the silent film era) the book was 1 of the fastest reads ever and I ate it up quick as I could.
