This was an interesting read and I have loaned the book to friends and am waiting for them to finish it so we can discuss it. I believe the author's conclusions are quite plausible, but I do not believe his proof of evidence is neccesarily iron-clad. I have since read on the internet of another possibility (as to "who dunnit") which actually makes a lot of sense. But I do not wish to give anything away about the ending or possibly who commited the crime so as to not spoil the reading for those who have not read it. It was truly a thought-provoking read, though I would have preferred it to be fleshed-out a bit more. I had many unanswered questions that research probably would have provided. But, all-in-all, an enjoyable read and I did not put it down until I had read it through.
