I let Carla in – no central locking – and walked around to the driver side, taking an appraising look at her in the process. She was calmer now that it was all over, but she looked a little tired and a little old. That wasn’t surprising: having someone you love commit suicide has to be one of the nastiest low blows life can throw at you. In other respects, she was still very much the woman I’d known back in the early 1990s, before she’d ever met John – when she was a brassy, loud blonde I’d met at a poker session and almost gone to bed with, except that my fear of intimacy and her preference for older men had kicked in at about the same time and turned a promising fumble into an awkward conversation about micro-limit hold ’em. There’s a line in a Yeats poem somewhere where he asks whether your imagination lingers longest on a woman you won or a woman you lost: while you’re puzzling over that one, you can maybe give him an estimate on how long a piece of string is. If things had worked out differently, Carla and me could have got a whole Mrs Robinson thing going, although even in those days I was less of a Benjamin Braddock, more of a Ratso Rizzo.

I started the car and pulled away, noticing that the priest followed us with his sad-eyed gaze as we drove by. I sympathised, up to a point: it couldn’t be an easy way to earn a living these days.

We eased our way out between the Breather pickets, collecting a fair share of abuse and ridicule along the way but no actual missiles or threats. Most of the people waving placards and chanting rhythmically were in their teens or early twenties. What did they know about death? They hadn’t even got that far with life yet.

The cemetery was all the way out in Waltham Abbey, and John and Carla lived – or rather Carla still lived and John didn’t any more – on Aldermans Hill just outside Southgate, in a flat over a dress shop. It was going to be a long haul, and the Vectra handled like a half-swamped raft. Joining the traffic, I remembered the half-bottle of Metaxa in my inside pocket, fished it out one-handed and passed it across to Carla. She took it without a word, unscrewed the top and downed a long swallow. It made her shudder: probably it made her eyes water, too, but there were plenty of other explanations available for why she rubbed the heel of her hand quickly across her face.

Looking in the rear-view mirror, I noticed that we’d picked up a tail. I swore under my breath. It was one of the vans that the Breathers had arrived in – a big high-sided delivery truck that someone must have borrowed from work, deep blue and with the words Bowyer’s Cleaning Services written in reverse script over the windscreen because a good idea is a good idea, even if the emergency services think of it first. I didn’t mention it to Carla: I just switched lanes whenever I could to make life harder for them. I was confident that I could lose them long before we got back into London.

‘So what was all that shit with the lawyer?’ I asked. It sounds tactless, put like that, but I’ve always found anger a good corrective to grief. Grief paralyses you, where a good head of hacked-off biliousness keeps you moving right along, although it’s not so great for making you look where you’re going.

Carla shook her head, as though she didn’t want to talk about it, and I was going to let it lie. But then she took a second pull on the brandy bottle and away she went.

‘John had always said he wanted to be buried at Waltham Abbey, next to his sister Hailey,’ she muttered. ‘Always. She was the only person he ever loved, apart from me. But he wasn’t himself, Fix. Not for months before he died. He wasn’t anyone I recognised.’

She sighed deeply and a little raggedly. ‘There’s a condition – EOA, it’s called. Early-onset Alzheimer’s. It got John’s dad when he was only forty-eight, and by the time he turned fifty he couldn’t even dress himself. John was convinced that Hailey was starting to get it just before she died, and he was always terrified he was going to go the same way. He tried to make me promise once that I’d give him pills, if it ever took him. If he ever got to the point where – you know, where there was nothing left of him. But I couldn’t, and I told him I couldn’t.

‘Anyway, just because it can run in families doesn’t mean it will. You don’t know, do you? There’s no point running halfway to meet trouble. But he’d have days when he couldn’t move, hardly, for brooding about it. I just tried to jolly him along when he was in one of those moods. Wait for him to pull out of it again, and then most times he’d say he was sorry he’d worried me and that’d be that.

‘But a couple of months before Christmas he went through a bad time. He had a job on – something that was going to pay really well, but it seemed to prey on his mind a lot.
