But she abandoned the lessons when she began using her new-found skills in unconstructive ways. There wasn’t a local gym class on earth that would teach her the skills she needed to defend her against herself.

Becky tries not to panic about how much she has to do, how she will manage a day’s work, a flight to Cannes and a couple more hours’ peppiness for all those new people who will need impressing. All on no sleep whatsoever? Back in her bedroom she lightly folds a dress and rolls up a cotton shirt and two T-shirts. Fills her washbag. Pulls out pants and socks and assembles it all in a pleasing jigsaw inside her carry-on suitcase: two carbon-scented copies of the Medea script at its base.

She makes notes on her Cannes meetings, banishing thoughts of that silken hair spilling out onto the kitchen floor, coming up with six ways to pitch her idea to six different kinds of people.

But she knows what she really wants to do and she knows that it is destructive so she fights it, at first holding her own hand lightly, reassuringly, like a friend. And then when the feeling does not subside, gripping her hand tightly, before grasping at the thin skin and raised veins of her own wrist, holding it tight, as if pulling herself back from a fight. She has agreed, in therapy, that standing up to this instinct is a good thing. Succeeding means she has taken her power back, or something like that; but without sleep all those rules are dissolving at their margins, her desires pushing away old decisions.

Surely if she just does more, the instinct will leave? She clears the washing basket. Cleans surfaces that already gleam. Lays out an array of jams and breakfast cereals despite the fact she never eats breakfast and her daughter’s favourites are firmly established and unflinching.

She means to make a cup of tea next, but somehow before the kettle boils she has opened Scott’s Twitter page and she is already on her way to losing the fight.

Becky has two Twitter accounts: one that is her. And one that isn’t.
