“And I should have asked him if everything was all right, and I should have told him to take care, and that it didn’t matter if he was late, and I should have said I loved him very, very much. Or no, no, that’s not it, that’s not it at all. I should have told him to come home at once, to cancel whatever arrangement he had made. I should have shouted and insisted and said I was upset and I needed him. I could have done. I nearly did. A whole other story unwinds from that, the story that never happens and which I’ll never get to tell, which is about a long life and happiness. Instead, I said goodbye rather coldly and slammed the phone down, and that was the last time I heard his voice, except on my answering machine. And sometimes I wake at night and think he’s talking to me. He’s saying, ‘Good morning, gorgeous, did you have nice dreams?’

“You heard the argument, anyway, or at least his end, because you came into his office halfway through. He put down the phone and turned to you, saying I was a bit pissed off with him, and you told him you were sure it would blow over.

I see exactly the way his head was tipped, the small muscle clenching and unclenching in his jaw. He closed his eyes and thought of me feeling downcast about not getting pregnant, and suddenly his irritation seeped away and he simply felt tender. So he sent me a text. ‘Sorry sorry sorry sorry sorry. Im a stupid fool.’

“He stood up. He put on his jacket. He put his head around Tania’s door and said he’d see her tomorrow. He waved at you as he went. He ran down the stairs two at a time, the way he always did. He got into the car and drove to King’s Cross. Five minutes, and he’d drive home and barely be late.

“He pulled up and Joe opened the passenger door and climbed in, carrying a bag. He said there was something he needed to show Greg. Of course Greg knew he could trust Joe. He loved Joe, after all, looked up to him and often turned to him for advice. In many ways, Joe was the father figure Greg had never really had. So Greg innocently followed Joe’s instructions and they drove east, toward Stratford, toward Porton Way. He would never have suspected anything was wrong. Why should he? How could he have done?
