‘I thought I should be here too,’ said Felicity.

‘Did you now?’ said Tess. She couldn’t bear to look at Felicity. ‘So what happens next?’

Asking the question filled her with a fresh nauseous wave of disbelief. Surely nothing was going to happen. Surely Felicity would rush off to one of her new gym classes and Will would come upstairs and talk to Liam while he had his bath, maybe get to the bottom of the Marcus problem, while Tess cooked a stir-fry for dinner; she had the ingredients ready, it was too bizarre, thinking of the little plastic-wrapped tray of chicken strips sitting staidly in the refrigerator. Surely she and Will were still going to have a glass of that half-empty bottle of wine and talk about potential men for the brand-new beautiful Felicity. They’d already canvassed so many possibilities. Their Italian bank manager. The big quiet guy who owned their local deli. Never once had Will slapped his hand to his forehead and said, ‘Of course! How could I have missed it? Me! I’d be perfect for her!’

It was a joke. She couldn’t stop thinking that the whole thing was a joke.

‘We know nothing can make this easy, or right, or better,’ said Will. ‘But we’ll do whatever you want, whatever you think is right for you and for Liam.’

‘For Liam,’ repeated Tess, dumbstruck.

For some reason it hadn’t occurred to her that Liam would have to be told about this, that Liam would have anything to do with it, or be in any way affected. Liam who was upstairs right now, lying on his stomach, watching television, his little six-year-old mind filled with giant-sized worries of Marcus.

No, she thought. No, no, no. Absolutely not.

She saw her mother appearing at her bedroom door. ‘Daddy and I want to talk to you about something.’

It would not happen to Liam the way it had happened to her. Over her dead body. Her beautiful, grave-faced little boy would not feel the loss and confusion she’d felt that awful summer all those years ago. He would not pack a little overnight bag every second Friday. He would not have to check a calendar on the refrigerator to see where he was sleeping each weekend. He would not learn to think before his spoke whenever one parent asked a seemingly innocuous question about the other.

Her mind raced.

All that mattered now was Liam. Her own feelings were irrelevant. How could she save this? How could she stop it?

‘We never, ever meant for this to happen.’ Will’s eyes were big and guileless. ‘And we want to do this the right way. The best way for all of us. We even wondered –’

Tess saw Felicity shake her head slightly at Will.

‘You’d even wondered what?’ said Tess. Here was more evidence of their talking. She could imagine the enjoyable intensity of these conversations. Teary eyes demonstrating what good people they were, how they were suffering at the thought of hurting Tess, but what choice did they have in the face of their passion, their love?

‘It’s too soon to talk about what we’re going to do.’ Felicity’s voice was firmer suddenly. Tess’s fingernails dug into her palms. How dare she? How dare she talk in her normal voice, as if this was a normal situation, a normal problem.

‘You even wondered what?’ Tess kept her eyes on Will.

Forget about Felicity, she told herself. You don’t have time to feel angry. Think, Tess, think.

Will’s face went from white to red. ‘We wondered if it would be possible for all of us to live together. Here. For Liam’s sake. It’s not like this is a normal break-up. We’re all . . . family. So that’s why we thought, I mean, maybe it’s crazy, but we just thought it might be possible. Eventually.’

Tess guffawed. A hard, almost guttural sound. Were they out of their minds? ‘You mean, I just move out of my bedroom and Felicity moves in? So we just say to Liam, “Don’t worry, honey, Daddy sleeps with Felicity now and Mummy is in the spare room?”’

Felicity looked mortified. ‘Of course not.’

‘When you put it like that –’ began Will.

‘But what other way is there to put it?’

Will exhaled. He leaned forward. ‘Look,’ he said. ‘We don’t need to work anything out right this second.’ Sometimes Will used a particularly masculine, reasonable but authoritative tone in the office when he wanted things done a certain way. Tess and Felicity gave him absolute hell about it. He was using that tone now, as if it were time to get things under control.

How dare he.

Tess lifted her closed fists and slammed them down so hard on the table that it rattled. She’d never done such a thing before. It felt farcical and absurd and somewhat thrilling. She was pleased to see both Will and Felicity flinch.

‘I’ll tell you what’s going to happen,’ she said, because all at once it was perfectly clear.

It was simple.

Will and Felicity needed to have a proper affair. The sooner the better. This smouldering thing they had going had to run its course. At the moment it was sweet and sexy. They were star-crossed lovers, Romeo and Juliet gazing soulfully at each other over the purple Cough Stop dragon. It needed to get sweaty and sticky and sleazy and eventually, hopefully, God willing, banal and dull. Will loved his son, and once the fog of lust cleared, he’d see that he’d made a ghastly but not irretrievable mistake.

This could all be fixed.

The only way forward was for Tess to leave. Right now.

‘Liam and I will go and stay in Sydney,’ she said. ‘With Mum. She called just a minute ago to say she’s broken her ankle. She needs someone there to help her.’

‘Oh no! How? Is she okay?’ said Felicity.

Tess ignored her. Felicity didn’t get to be the caring niece any more. She was the other woman. Tess was the wife. And she was going to fight this. For Liam’s sake. She would fight it and she would win.

‘We’ll stay with her until her ankle is better.’

‘But, Tess, you can’t take Liam to live in Sydney.’ Will’s bossy tone vanished. He was a Melbourne boy. There had never been any question that they would live anywhere else.

He looked at Tess with a wounded expression, as if he were Liam being unjustly told off for something. Then his brow cleared. ‘What about school?’ he said. ‘He can’t miss school.’

‘He can go to St Angela’s for a term. He needs to get away from Marcus. This will be good for him. A complete change of scenery. He can walk to school like I did.’
