Regarding the book -
All of us on here are interested in mysteries, right? Say we buy Renner's book, if and when it ever comes out. Or a book about someone else who vanishes like Maura has. Maybe it's saved on your Kindle or tossed in a rucksack or the boot of your car.
Then imagine the unthinkable happens, and one of us vanishes.
You could bet anything that, if the fact you were interested in mystery disappearances was made public, then there would be plenty of people suggesting that you vanished deliberately. I mean, look - he had a book about mysterious disappearances in his holdall! That's no coincidence
My point is that is really, really isn't unusual for people to own books about their favorite hobby. Maura loved hiking in the White Mountains - therefore, should we really pay so much attention to the fact that she owned a book about hiking in the White Mountains?
I was actually away when the 'hairdresser' story broke, and I've been playing catch-up ever since. It has in no way affected my opinion on the case. I like to try to explore things from different angles, so I have asked questions about that photo (I'd truly love to be proven wrong, and have Maura found safe, happy and well somewhere), but it was an attempt to understand the story better, and the potential ramifications if Maura was ever 'found' but didn't want to be discovered.
