Investigation into why Madeleine McCann's parents Kate and Gerry have found it so hard to shake off the suspicion that they somehow had a role in her disappearance. Richard Bilton talks to those who had direct contact with the McCanns at the time and travels to Portugal to question those close to the case in an attempt to separate fact from fiction, to investigate some of the claims made against the couple and to question what remains of the evidence.
