For me,there's no doubt no abduction took place. What I would like to know is, why start off by lying through your teeth.
If there had been unidentified prowlers wandering around Ocean Club that night surely someone would have seen them? After all, there was a constant trail of guests wandering back and forth from the tapas bar and restaurant adjacent to the block from where Madeleine disappeared. Additionally, people like Jez Wilkins were out walking, another local girl was visiting her boyfriend nearby. Waiters and other members of staff were coming and going, a veritable race track yet we are led to believe someone got through completely unnoticed and took a young girl from her parents apartment.
Scotland Yard in the guise of DCI Andy Redwood appears to have destroyed the one and only mystery man seen was walking past block 5 with a child in his arms. So all in all somewhat of a mystery?
