‘David Carey,’ he said. ‘Also family liaison.’

‘In case it’s a big family,’ said Guleed.

It’s always important to get to the victim’s relatives quickly, partly because it’s just common decency to give them the news before they see it on TV, partly because it makes us look efficient but mostly because you want to be looking them in the face when they hear the news. Genuine surprise, shock and grief being hard to fake.

Rather Guleed and Carey than me.

Notting Hill is three kilometres west of Baker Street, so we were there in under a quarter of an hour and would have been faster if I hadn’t got turned around near Portobello Road. In my defence, at night all those late-Victorian knock-off Regency town houses look the bleeding same, and I’ve never spent that much time in Notting Hill outside of Carnival. It didn’t help that Guleed and Carey both had their phones on GPS and took it in turns to give me contradictory directions. I finally spotted a landmark I recognised and pulled up outside the Notting Hill Community Church. It has a Pentecostal congregation and is just the sort of noisy and fervent place my mum favours on those rare occasions when she remembers she’s supposed to be a Christian.

My dad only attended a church if he rated their band, so you can imagine how often that happened. When I was really young I liked the dressing up in the good clothes and there were usually other kids to play with, but it never lasted. After a couple of months my mum would get a Sunday cleaning gig or pick a fight with the pastor or just lose interest. Then we’d go back to Sunday being a day I got to stay in and watch cartoons and change records on my dad’s turntable.

I got out of the car and into an eerie silence. The air was still, sounds were muffled, the shop windows were blind in the flat yellow glare of the street lamps and had the artificiality of a film set. The clouds were low and sullen with reflected light. The slam of the car doors was muffled in the moist air.

‘It’s going to snow,’ said Carey.

It was certainly cold enough. I could stick my hands in my pockets but my ears were starting to freeze. Guleed pulled a big furry hat with ear flaps down over her hijab and looked at me and Carey, bare-headed and frozen-eared, with amusement.

‘Practical and modest,’ she said.

Neither of us gave her the satisfaction of an answer.

We headed for the mews.

‘Where did you get the hat?’ I asked.

‘Nicked it off my brother,’ she said.

‘I heard it gets cold in the desert,’ said Carey. ‘You’d need a hat like that.’

Guleed and I exchanged looks, but what can you do?
