I finally have uploaded some video clips from investigative trips to the Queen Mary, including the clip mentioned in Jeff's book. I believe it is the middle of page 26 or 27 (forgive me, don't have it in front of me at the moment) where Peter James talks about the doll ribbon being pulled.
If you will visit my website, and click on the "Video" button, you will see a link to that very video.
Hope you enjoy it, and thanks Jeff for writing about it in your book!
