When did Number 6 take up the role of “childminder?” Number 6 told the three children a fairytale, as Number 2 observed. Was that the only fairytale he told them? After all the children made him promise that he would come back tomorrow, and Number 6 said he would seeing as he didn’t think he had any other important appointments! You will probably be familiar with the name Scheherazade.
Perhaps the Scheherazade connection is carrying this just a little too far. But it would all depend on how many times Number 6 had visited the nursery during his spell of child-minding, and how many fairytale's he told.
Be seeing you.
