Sadie is in the kitchen, already dressed in school uniform, fastening the clips on the violin she chose for her most recent birthday, when Gabriela heads downstairs the following morning. Seven years old: how the hell did that happen? Briefly, she wonders what the fall-out will be for Sadie, after all this. Will it send her over the edge? But there is no point trying to second-guess her daughter, whose emotions are always more nuanced, less discernible than her own at the same age. There is an air of pointedness about Sadie’s refusal to cause trouble for them in the way that Gabriela is prepared for that she finds unsettling. No, she reprimands herself, her fists tightening – it is not Sadie whose behaviour she needs fear.

‘Mum, have you seen my sheet music?’

As her daughter speaks, Gabriela’s eye catches the wine glasses from the night before, which stand marooned on the table where she is packing her school bag.

‘This what you’re looking for?’ Tom squeezes past cradling a cup and drops the pristinely kept wad of paper onto her school bag, winking at her as he settles on one of the chairs squeezed up against the kitchen table.

‘Made you a tea,’ he says and Gabriela fixes her jaw into a smile, moving forward to clear away the cereal bowls that will otherwise languish until she comes home, and then she stops. I will not be coming home. She hears the words as a whisper between her temples. There is a brief moment when she is struck by the enormity of it, but then she sees her son walking into the room and instantly everything is as it was. Once again she is Sadie and Callum’s mother and she is preparing for a normal day at the office, for a job that Tom watches her forfeit so much of their life together, without ever making her explain why. The job in which he has watched her rise through the ranks while he takes bit parts as a freelance architect, picking up the pieces without so much as a suppressed sigh.

‘Want me to walk you in?’ he asks Sadie, leaning back in his chair, rustling open yesterday’s copy of the Guardian. Sadie throws him the same look she has been giving him since she was a toddler – something between despair and total adoration. For the past few weeks, Tom has let her make the short journey alone and Gabriela can’t tell him why it makes her so uncomfortable, their child being so far out of their reach.

Enjoying the familiarity of the rapport between himself and Sadie, the reversal of the traditional parent/child roles, he shrugs, widening his eyes as if to say, What? We don’t have to leave for five minutes.

‘Leave the girl alone,’ Gabriela plays along, batting his feet off the table as she passes, sweeping up the trail of cups and bowls and opening the dishwasher.
