Tess watched in bemusement as Cecilia whirled around the kitchen. Within seconds she’d stowed the dishes in the dishwasher, put the cereal away in a giant pantry and was polishing the kitchen sink with a paper towel.

‘We ran unusually late this morning,’ explained Cecilia as she scrubbed at the sink as if her life depended on it. ‘Normally I can’t leave the house unless everything is perfect. I know I’m ridiculous. My sister says I have that disorder. What is it? Obsessive compulsive. That’s it. OCD.’

Tess thought her sister might have a point.

‘You should rest,’ she said.

‘Have a seat. Would you like a cup of tea? Coffee?’ said Cecilia frantically. ‘I have muffins, biscuits –’ She stopped, pressed her hand to her forehead and briefly closed her eyes. ‘Goodness. That is, ah, what was I saying?’

‘I think I should make you a cup of tea.’

‘I might actually need to –’ Cecilia pulled out a chair, and then stopped, transfixed by the sight of her shoes.

‘My shoes don’t match,’ she said, awestruck.

‘No one would have noticed,’ said Tess.

Cecilia sat down and rested her elbows on the table. She gave Tess a rueful, almost shy smile. ‘I have a reputation at St Angela’s for being the opposite of this.’

‘Oh, well,’ said Tess. She filled a very shiny kettle with water and noticed that she’d left a few droplets on Cecilia’s perfect sink. ‘Your secret is safe with me.’

Worried that she’d implied that Cecilia’s behaviour was somehow shameful, she quickly changed the subject. ‘Is one of your daughters doing an assignment on the Berlin Wall?’ She nodded at the pile of books on the table.

‘My daughter Esther is learning about it for her own interest,’ said Cecilia. ‘She gets crazily interested in these different topics. We all end up becoming experts. It can be a bit draining. Anyway.’ She took a deep breath and suddenly turned in her chair to face Tess as if they were at a dinner party and Cecilia had decided it was time to focus on her instead of the guest on her other side. ‘Have you been to Berlin, Tess?’

The pitch of her voice was not quite right. Was she about to be sick again? Could Cecilia be on drugs? Mentally ill?

‘No, actually.’ Tess opened Cecilia’s pantry door to find teabags and her eyes widened at the array of labelled Tupperware containers of all shapes and sizes. It was like a magazine ad. ‘I’ve been to Europe a few times but my cousin, Felicity –’ She stopped. She’d been about to say that her cousin Felicity wasn’t interested in Germany and so therefore she’d never been, and she was struck for the first time by what an odd thing that was to say. As if her own feelings about seeing Germany were of no consequence. (What were her own feelings about Germany?) She saw a tray set out with rows of teabags. ‘Gosh. You’ve got everything. Which tea would you like?’

‘Oh, Earl Grey, just black, no sugar. Really, please let me!’ Cecilia went to stand up.

‘Sit, sit,’ said Tess, almost bossily, as if she’d known Cecilia forever. If Cecilia was behaving unlike herself, so was Tess. Cecilia sat back down.

A thought occurred to Tess. ‘Will Polly need her sports shoes straightaway? Should I rush back to the school with them?’

Cecilia started. ‘I forgot about Polly’s sport again! I completely forgot.’

Tess smiled at how appalled Cecilia looked. It was like she was forgetting things for the first time in her whole life.

Cecilia said slowly, ‘They don’t go up to the oval until ten.’

‘In that case I’ll have a cup of tea with you,’ said Tess. She helped herself to an unopened packet of expensive-looking chocolate biscuits from Cecilia’s extraordinary pantry, somewhat thrilled by her temerity. Oh, this was living life on the edge, all right. ‘And a biscuit?’

Chapter twenty-four

Cecilia watched Tess lift her cup of tea to her mouth (she’d used the wrong mugs – Cecilia never used those mugs for guests) and smile at her over the rim, unaware of the terrible monologue running silently through Cecilia’s head.

Want to know what I found out last night, Tess? My husband murdered Janie Crowley. I know! Wow, hey. Yep, Rachel Crowley’s daughter, that’s right, the nice white-haired lady with the sad eyes, the one who walked past us this morning and looked me right in the eyes and smiled. So! I’m in a bit of a pickle to be honest, Tess, as my mother would say. A real pickle.

What would Tess say if Cecilia actually spoke those words out loud? Cecilia had thought Tess was one of those mysterious, self-assured types who didn’t need to fill silent gaps with conversation, but it occurred to her now that perhaps she was shy. There was something brave about the way she met Cecilia’s eyes and sat with careful, straight-backed posture, as if she was a child behaving well at someone else’s house.

She was really being very nice to Cecilia, driving her home after that humiliating incident in the gutter. Was Cecilia going to throw up every time she saw Rachel Crowley from now on? Because that could be complicated.

Tess tilted her head at the Berlin Wall books. ‘I always like reading about the escape attempts.’

‘Me too,’ said Cecilia. ‘The successful ones, that is.’ She opened one of the books to the section of photos in the middle. ‘See this family?’ She pointed at a black and white photo of a young man and woman and their four small, scruffy children.
