while I wasn't expecting much because I have read and watched so many mysteries that some just become predictable but this was not. It had me guessing till the very end and i had no idea about where it would go until the final page. Israel presents 2 conclusions which both seem plausible where only one is true and it is done so well I truly never saw it coming from the beginning till the end. The only reason I give it 4 stars is that it took so long for us to get any remnant of an answer to the problem that I was 20 pages left and felt like I had learnt nothing. There was no air of mystery or any solving of the problem till the end, there was no set journey.
