You make many claims about Amaral's book. but seem unable to provide cites to support your allegations. Rumours of what he said are worthless, provide cites!
There's no excuse for total ignorance whoever you are. If Collins can't get the simple facts right it nullifies anything else he might say.
I can only assume you haven't read Amaral's book.
With regard to not getting simple facts right - he claims JT 'formally' identified Murat. That is untrue - and there is nothing in the files to support his claim.
He states as a fact that it was definitely Madeleine who was heard crying on he 1st May - even though she was never named as definitely being that child in a statement. He refers to 'a neighbour' who claims to have heard Madeleine crying for 1.l/4 hrs to avoid mentioning Mrs Fenn's name.
He then goes on to claim that Madeleine spoke to her parents the very next morning (the 2nd). That is untrue. IMO he changed the date from the true date of the 3rd to the 2nd in an attempt to convince the reader it WAS Madeleine who cried the night before on the 1st.
Amaral then claims that Madeleine asked her parents why they didn't come when SHE cried. No mention of Sean at all - thus removing the inconvenient fact that Mrs Fenn only heard one child crying and not two as claimed by Madeleine.
IMO the above are several examples of him 'not getting simple facts right'. His book is littered with them
