Other mistake: Richard does not possess psychic powers, but he grabs from the shelf the one book that is a key plot point; the book is amongst many others in a bookcase full of texts. It does not stick out literally or figuratively in any way and most importantly, it does not feature the professor's name on the spine - that is probably where the issue lies; manufacturing the prop they did not leave any clue about the professor that Richard could have picked up - the name is merely on the front and back.

Other mistake: The show, shot in Guadeloupe, part of France, is set in the fictional island of Saint Marie, British overseas territory, with English as official language. When we see the development company sign a big cheque to the local university, it is to the order of University of Guadeloupe (also non-existent, since the university in Guadeloupe would have been in 2012 the University of the French West Indies and Guiana). Incidentally, the document that supposedly incriminating picture (taken at an amazingly public event including giant cardboard fake cheque) is from, is a form about real estate in Nevada. (00:20:50)
