The former Portuguese chief investigator leading the search for missing British toddler Madeleine McCann has reportedly written an "explosive" new book about the inquiry into her disappearance.
According to the U.K.'s Observer Newspaper, Goncalo Amaral plans to launch his book, True Lies, on Thursday, just days after the case is expected to officially close.
Earlier this month police completed their final report into the disappearance of McCann. Prosecutors on Monday are expected to wrap up a 14-month investigation and drop the child's parents — Kate and Gerry — of their 'suspect' status, the paper wrote.
In the book Amaral, who believes the child is dead, criticizes the role of the British police in the investigation and suggests that they were influenced by the leads that the parents wanted pursued, the Observer said.
Under Portuguese law, case documents will be available to the public three weeks after the case is closed.
Madeleine McCann disappeared in Portugal's southern Algarve region during a family vacation in May 2007, a few days before her fourth birthday. Detectives named her parents and local man Robert Murat as formal suspects in the case. All denied involvement in Madeleine's disappearance.
