I thought, on average, Euro-cops were just plain bad, but this must take the cake.
I also thought one of the first questions a complete investigation would ask is:
May we have a list of ex-employees - say, going back a year.
Have you gotten any nasty emails, letters, etc?
And so on.
Is it clear whether the maid would have been an employee of the McCann's or an employee of the hotel? An employee of the hotel (former) would be in the area, I suppose. But would a former employee of the McCanns be in the area? Would she have been fired while on the trip?
I'm not sure I get it.
