So, I have opened up a can of worms for the police to look into and investigate! My powers of deduction are often and quite frequently proven to turn out right, in one way or another, and I feel certain that the existence of the third creche helps to resolve some of the contradictions thrown up by (a) Stephen Carpenters assertion that he (they) had dropped his children off at the creche and collected them from the creche, and (b) either side of him playing tennis with Gerry McCann from 2pm onwards on the afternoon Thursday 3rd May 2007..
The solution is a relatively simple one, in that the Carpenters were using the third creche (the privately owned one that I have identified), so I will give Carpenter the benefit of doubt regarding what he said about taking his children to the creche and collecting them on that afternoon...
