‘I told you, I need to work every day next week so I’m stockpiling. Like a squirrel.’ She wraps an old washed out ice-cream tub with cling film and hands it to him. ‘This is for your tutor.’ She had been sending food parcels to anyone related to Malachi’s education since his first semester of university. Anything to boost the boy’s chances. ‘The rest is for your freezer.’

‘Thanks. I appreciate it.’

‘And I appreciate if you put on some weight. What is this?’ She pinches the flesh of his side.

‘Ow.’

‘Heroin chic!’ she announces. ‘I saw it on GMTV. Teenagers with bodies like this.’ Mary holds up her pinkie finger. ‘No woman wants that, Malachi. You need to eat properly.’

She had looked in Malachi’s and Tristan’s fridge a few days ago and saw nothing but a loaf of value bread and jar of lemon curd. The freezer was even worse: a half empty box of fish fingers and two frosty bottles of Hooch, which Tristan explained were ‘for the ladies’. If their nan knew they were eating so poorly under Mary’s watch there would be murder.

‘Freezer, you hear me? Tell your brother he can’t eat, eat, eat all in one sitting. And why has he got zigzags shaved in his hair? Does he think he’s a pop star or something?’

‘You know what he’s like. He’s a little wild.’

‘He can’t afford to be wild.’ Mary tries to put the word in air quotes but uses eight fingers and makes a baby waving motion. ‘Too many riffraffs around here going wild like this.’ She makes a stabbing gesture and tries to look menacing, but her only reference point is West Side Story and she makes a dance of it.

Malachi puts a hand under a piece of kitchen roll and drags out a bamboo skewer of prawns. Mary slaps him.

‘Did you hear me say help yourself? Does this look like the Pizza Hut buffet to you?’

‘You just told me I need to eat.’

‘Not prawn. Too early for prawn.’ She turns her back to him as she rewraps the skewers. His eyes burn her; she must explain her snappy mood. ‘I need to leave my spare keys with you in case David gets in early. He’s on standby for a flight so could be here tonight, tomorrow or next week. Oh God.’ The reality of him arriving hits her again. It sends her elbow into overdrive.

‘David?’

‘Yes, David, my husband. Remember him?’ There’s a hysterical edge to her voice. She puts a hand on her forehead to save herself as Oprah has taught her. ‘I don’t even want to talk about it.’

‘I didn’t know David was coming back.’

‘No. But we didn’t know Jesus was coming back either.’
