‘Connor,’ said Tess. ‘Connor Whitby. He’s her PE teacher.’ She thought of him last night at the service station, his helmet under one arm.

‘Yes, that’s right. All the little girls are in love with him. Actually, half the mothers are too.’

‘Really.’ Slosh, slosh went that waterbed.

‘Good morning, Tess. Hi there, Cecilia.’ It was Rachel Crowley, the school secretary, walking from the other direction, wearing a pair of white running shoes with her businesslike skirt and silk shirt. Tess wondered if anyone ever looked at Rachel without thinking about Janie Crowley and what had happened to her in that park. It was impossible to think that Rachel had once been an ordinary woman, that no one could have sensed the tragedy that was waiting for her.

Rachel stopped in front of them. More conversation. It was endless. She looked tired and pale, her white hair not quite as beautifully blow-dried as it had been when Tess had met her yesterday. ‘Thanks again for the lift home last night,’ she said to Cecilia. She smiled at Tess. ‘I was at one of Cecilia’s Tupperware parties last night and had too much to drink. That’s why I’m on foot today.’ She gestured at her shoes. ‘Shameful, isn’t it.’

There was an awkward silence. Tess had confidently expected Cecilia to speak next, but she seemed distracted by something off in the distance and was strangely, almost bizarrely silent.

‘Sounds like you had a fun night,’ said Tess finally. Her voice sounded too loud and hearty. Why couldn’t she just speak like a normal person?

‘It was actually.’ Rachel frowned slightly at Cecilia, who still hadn’t said a word. She turned her attention back to Tess. ‘Did Liam go off to his classroom okay?’

‘Miss Applebee took him under her wing,’ said Tess.

‘That’s good,’ said Rachel. ‘He’ll be fine. Trudy takes special care of the new children. I’d better go start my day. Get out of these ridiculous-looking clodhoppers. Bye girls.’

‘Have a great –’ Cecilia’s voice came out husky and she cleared her throat. ‘Have a great day, Rachel.’

‘You too.’

Rachel headed off towards the school.

‘Well,’ said Tess.

‘Oh dear,’ said Cecilia. She pressed her fingertips to her mouth. ‘I think I’m going –’ She looked around her agitatedly, as if she was searching for something. ‘Shit.’

And suddenly she was crouched in the gutter being violently sick.

Oh God, thought Tess as the awful retching sounds went on and on. She did not want to see Cecilia Fitzpatrick being sick in a gutter. Was it a hangover from the previous night? Food poisoning? Should she crouch down beside her and hold back her hair like girlfriends did for each other in nightclub toilets after too many tequilas? Like she and Felicity had once done for each other? Or should she gently rub Cecilia’s back in a circular motion like she did for Liam when he was sick? Should she at least make some soothing, sympathetic sounds as she stood here watching, to show she cared? Rather than just standing here, wincing and looking the other way? But she barely knew the woman.

When she was pregnant with Liam, Tess had suffered from chronic all-day-long morning sickness. She’d thrown up in numerous public places, and her only wish had been to be left alone. Perhaps she should slip quietly away? But she couldn’t just abandon the poor woman. She looked around her desperately for another school mum, one of those capable sorts who would know what to do. Cecilia would have dozens of friends at the school, but the street was suddenly deserted and quiet.

Then she was struck by a wonderful inspiration: tissues. The thought of being able to offer Cecilia something both useful and appropriate filled her with something ridiculously akin to joy. She rustled through her handbag and found a small unopened packet of tissues and a bottle of water.

‘You’re like a boy scout,’ Will had said to her early on in their relationship when she’d pulled a small flashlight from her bag after he’d dropped his car keys on a dark street on their way home from a movie. ‘If we got stuck on a desert island we could be self-sufficient thanks to Tess’s handbag,’ Felicity had said, because, of course, Felicity had been there too, that night, she remembered now. When had Felicity ever not been there?

‘My goodness me,’ said Cecilia. She straightened up, plonked herself on the kerb and wiped the back of her hand across her mouth. ‘How embarrassing.’

‘Here.’ Tess handed over the tissues. ‘Are you all right? Was it something you maybe . . . ate?’ Cecilia’s hands, Tess noticed, were trembling badly and her face was pasty white.

‘I don’t know.’ Cecilia blew her nose and looked up at Tess. There were purplish crescents under her streaming eyes and tiny flecks of mascara on her eyelids. She looked dreadful. ‘I’m so sorry about this. You must go. You’ve probably got a million things to do.’

‘I don’t actually have a thing to do,’ said Tess. ‘Not a thing in the world.’ She undid the bottle cap. ‘Sip of water?’

‘Thank you.’ Cecilia took the water bottle and drank. She went to stand up and staggered. Tess grabbed her arm just before she fell.

‘Sorry, so sorry.’ Cecilia was almost sobbing.

‘It’s fine.’ Tess held her up. ‘It’s perfectly fine. I think I should drive you home.’

‘Oh, no, no, that’s so sweet of you, but I’m really fine.’
