The diary is of course pure fiction, no one writes a diary in this context. Something interesting though, McCann was obviously away, Kate collected him from the airport on June 20th, and she writes......
'I want to speak to someone now, but it's too late.
I changed my mind and I sent a text message to Ricardo (Portuguese police family liaison officer). I don't know if was a sensible idea but I feel really annoyed. '
I am not sure will have to check the dates but was this the time she rang Ricardo about her dream of Madeleine buried on the hill ? she speaks of this hill often.
