Twelve things.

Every one of them true.

Every single one of them independently verifiable and eleven of them documented.

And the conclusion I drew from them, which I held with total conviction for about sixteen weeks, was this:

That my sister and her husband knew the child was badly injured; that they understood that whoever presented her at a hospital would be inside the timeline; that they therefore selected the one relative in the family who would not telephone before acting; that they drove past a grandmother and three urgent care centres to deliver her to that person; and that they then placed themselves together, in public, on camera, with receipts, for the duration of the window they had just created.

I want to record how that theory felt, because it is the only way anybody will understand why I could not put it down.
