‘It’s about revenge,’ she had told him excitedly, not realizing that you can stop once somebody has said yes. ‘Medea sacrifices everything to help Jason achieve his goals. Then, when he’s taken all she has to offer, he gets bored and leaves her for another woman. And so Medea gets angry.’

As she spoke, something scalding had coursed through her, with the rush of a furiously filling lock. It didn’t take much to connect with this feeling, not really, it was close to the surface wherever she was. ‘He believes a woman’s anger isn’t ever something to worry about,’ she said, ‘but he underestimates her. Medea takes her revenge.’

It didn’t matter that Matthew would never know what had lit that touchpaper inside her. She could see from his half-smile that he was interested in her, and proud of her, and she was already addicted to that feeling.

Becky steps into the road to cross it and a car swerves to avoid her, blaring its horn. Its headlights catch her shins. She steps back, a stomach-twisting jolt of adrenaline waking her up.

On the opposite side of the road an old woman takes pleasure in shaking her head at Becky’s near-fatal mistake as a new story sweeps away red carpets and lofted award statuettes: Becky, mother of one, a development assistant with no produced credits, dead in the road. A head full of dreams, but not enough blood left in her veins to keep them there.

It is an old feeling for Becky, the idea that her waking life might be parted from her body. That her body is sometimes simply a place where things happen, sometimes with her, sometimes without.

These are not helpful thoughts.

She feels small and foolish now. She is a woman without real power. A woman who can barely cross a road. She has the favour of a powerful man, and that is all. For all the cocktails and glamorous lunches, it hasn’t happened yet, the film hasn’t taken off, hasn’t been made. It’s all just words and expressions of interest. Who on earth does she think she is?

She crosses, safely now, passing the old woman who wants desperately to catch Becky’s eye.

Smaller and weaker, she arrives at the side entrance to Matthew’s house, electing to take a route she has taken a dozen times before, stepping down a flight of double-height steps to a wooden door, barbed wire all curled at the top like a helix of DNA. The air smells of fresh creosote and good maintenance and charred meat and through a small side window she can see that lights are on deeper inside the house.
