And under it, folded in half, was the top half of a printed pharmacy label that had been torn off a bottle.

Reyes read it, and then she handed it to Sarah Jenkins, and Sarah Jenkins read it and said one word, and then she turned around and went back through the door at a speed I had not previously seen her move.

The name on that label was not Delilah Sinclair.

It was Douglas Sinclair.

It was an adult prescription, filled in his name, for a sedative that is not given to children — not as an off-label judgment call, not at a reduced dose, not at all — and that carries a boxed warning to that effect.

I do not want to name it and I have never named it in any public setting, and there is a reason for that which I will come to.
