Dr Yue seemed highly intelligent because he wore glasses, and perhaps because he was Asian, which was racial stereotyping, but Cecilia didn’t care. She hoped that Dr Yue’s mother had been one of those pushy tiger mothers. She hoped poor Dr Yue didn’t have any other interests apart from medicine. She loved Dr Yue. She loved Dr Yue’s mother.

But John-bloody-Paul! John-Paul didn’t seem to understand that they were speaking to God. He kept interrupting. He sounded too brusque. Rude, almost! If John-Paul offended Dr Yue, he might not try as hard for Polly. Cecilia knew that this was just a job for Dr Yue, and Polly was just another one of his patients, and that they were just another pair of distraught parents, and everyone knew that doctors were overworked and got exhausted and made tiny errors, like airline pilots, that turned out to be catastrophic. Cecilia and John-Paul had to differentiate themselves in some way. They had to make him see that Polly wasn’t just another patient, she was Polly, she was Cecilia’s baby girl, she was her funny, infuriating, charming little girl. Cecilia’s breath caught, and for a moment she couldn’t breathe.

Dr Yue patted her arm. ‘This is incredibly distressing for you, Mrs Fitzpatrick, and I know you’ve had a long night with no sleep.’

John-Paul glanced sideways at Cecilia, as if he’d forgotten she was there too. He took her hand. ‘Please just go on,’ he said.

Cecilia smiled obsequiously at Dr Yue. ‘I’m fine,’ she said. ‘Thank you.’ Look how very nice and undemanding we are!

Dr Yue ran through Polly’s injuries. A serious concussion, but the CT scan had showed no sign of a serious brain injury. The pink sparkly helmet had done its job. As they already knew, internal bleeding was a concern, but they were monitoring and so far, so good. They already knew that Polly had suffered severe skin abrasions, a fractured tibia and a ruptured spleen. The spleen had already been removed. Many people lived without their spleens. She might have some danger of reduced immunity, and they would recommend antibiotics in the case of –

‘Her arm,’ interrupted John-Paul. ‘The main concern through the night seemed to be her right arm.’

‘Yes.’ Dr Yue locked eyes with Cecilia and breathed in and out, as if he was a yoga teacher demonstrating breathing techniques. ‘I’m very sorry to say that the limb is not salvagable.’

‘Pardon?’ said Cecilia.

‘Oh God,’ said John-Paul.

‘I’m sorry,’ said Cecilia, still trying to be nice, but feeling a surge of fury. ‘What do you mean not salvagable?’

It sounded like Polly’s arm was at the bottom of the ocean.

‘She’s suffered irreparable tissue damage, a double fracture, and there’s no longer sufficient blood supply. We’d like to do the procedure this afternoon.’

‘Procedure?’ echoed Cecilia. ‘By procedure you mean . . .’

She couldn’t say the word. It was unspeakably obscene.

‘Amputation,’ said Dr Yue. ‘Just above the elbow. I know this is terrible news for you, and I’ve arranged for a counsellor to see you –’

‘No,’ said Cecilia firmly. She would not stand for this. She had no idea what a spleen did, but she knew what a right arm did. ‘She’s right-handed you see, Dr Yue. She’s six years old. She can’t live without her arm!’ Her voice skidded into the ugly maternal hysteria she’d been trying so hard to spare him.

Why wasn’t John-Paul saying anything? The brusque interruptions had stopped. He had turned away from Dr Yue and was looking back through the glass panels at Polly.

‘She can, Mrs Fitzpatrick,’ said Dr Yue. ‘I’m so very sorry, but she can.’

There was a long wide passageway outside the heavy wooden doors that led to Intensive Care, beyond which only family members were allowed. A row of high windows let in dust-flecked rays of sunlight, reminding Rachel of church. People sat in brown leather chairs all the way along the passageway: reading, texting, talking on their mobile phones. It was like a quieter version of an airport terminal. People enduring impossibly long waits, their faces tense and tired. Sudden muffled explosions of emotion.

Rachel sat in one of the brown leather chairs facing the wooden doors, her eyes continually watching for Cecilia or John-Paul Fitzpatrick.

What did you say to the parents of a child you’d hit with a car and nearly killed?

The words ‘I’m sorry’ felt like an insult. You said ‘I’m sorry’ when you bumped against someone’s supermarket trolley. There needed to be bigger words.

I am profoundly sorry. I am filled with terrible regret. Please know that I will never forgive myself.

What did you say, when you knew the true extent of your own culpability, which was so much more than that assigned to her by the freakishly young paramedics and police officers who had arrived at the accident scene yesterday. They’d treated her like a doddery old woman involved in a tragic accident. Words kept forming in her head: I saw Connor Whitby and I put my foot on the accelerator. I saw the man who murdered my daughter and I wanted to hurt him.

Yet some instinct for self-preservation must have prevented her from speaking out loud, because otherwise, surely, she would be locked up for attempted murder.

All she remembered saying was, ‘I didn’t see Polly. I didn’t see her until it was too late.’

‘How fast were you going, Mrs Crowley?’ they asked her, so gently and respectfully.
