The McCann family’s book entitled Madeleine, published in May 2012, has already fetched around €1 million, it was reported in the UK press.
The money will be used to boost the fund created by the McCanns after the disappearance of their daughter in Praia da Luz on May 3 2007.
Meanwhile, a British newspaper claims to be in possession of photos of Madeleine accompanied by a man of around 50 years of age in Brazil.
The images were sent by a Brazilian who claims knowledge of the kidnappers. The British police are investigating the allegation.
According to the UK press report, one photograph shows Madeleine dressed in pale red trousers, a green shirt and a blue hat. The man with her is bearded and wearing shorts.
