One of the first things Paul Draper had done, he and Maddy chatting together on their first day in the squad, was to show her a photograph of his wife and kid. Alice and Ben. On holiday somewhere in the north-west. Blackpool. Morecambe. A faint suggestion of sea on the horizon. Alice in a two-piece swimsuit, not a bikini exactly, her figure not yet back to what it once had been, Ben in a little all-in-one on her knee. Alice having to narrow her eyes slightly against the light, but smiling nonetheless, her skin pale, as if unused to the sun.

'You must come round,' he'd said. 'We'll get a takeaway, eat in. Alice'd be chuffed with the company.'

Maddy never had.

Now she sat awkwardly on the edge of a chair. Alice slumped back on the two-seater settee opposite, the child fretting at her breast. Cups of tea on the table, half-cold. Biscuits, some broken fragments of rusk. There'd been photographers outside, a few; one reporter, insistent, from the local whatever-it-was, Journal or Gazette.

'Alice…'

At the sound of Maddy's voice, tears appeared again on Alice Draper's face. How could she not cry? Maddy thought. Twenty-three and a wee boy of no more than six or seven months and then this…

Maddy forced herself to her feet. Through the partly drawn curtains she could see the flats opposite, identical to the one in which she was standing; balcony upon balcony busy with tubs of flowers, rusting bicycles, washing twisting in the late-afternoon breeze. The dark already falling into place.

'It's not bad,' Draper had said. 'Not bad at all. Ex-council, couldn't afford it else. But okay. You wait till you see.'

He looked a little like that guitarist, Maddy had thought, the one who used to play with Morrissey.

Alice had said very little. Before being finally pronounced dead, her young husband had said nothing at all. Flowers from the Metropolitan Police Commissioner lay by the sink, waiting to be put in water. I'll do it before I go, Maddy thought. Wash these cups, make a fresh pot of tea. See if I can't persuade Alice to eat something, a sandwich at least.

While she was waiting for the kettle to boil, Alice switched on the television news.

'Alice,' Maddy said, 'are you sure this is a good idea?'

Colours unnaturally bright, Paul Draper's face flickered for a moment on the screen, then disappeared.

'Alice…'

Seated behind a bank of microphones, the Assistant Commissioner looked sombre yet purposeful.

'From all the information available to me, I have no doubt that the operation was carefully and professionally planned and executed with a high level of competence that does credit to all the officers involved. With regard to the tragic death of a young detective constable…'

Regardless of Alice's wishes, Maddy leaned forward and switched off the set.

Ben was wriggling in his mother's lap, whimpering against her chest.

'Alice, Alice. I think you might be holding him too tight. Do you want me to take him for a minute? Here. That's it. Just while you drink your tea.'

The baby's pale eyes looked at her in wonder when she lifted him towards her and Maddy felt something kick, hard, against the hollow of her insides. When Alice picked up the cup it slipped between her fingers, spilling tea across the table and the floor.

'Never mind,' Maddy said. 'I'll clean it up.'

Alice looked back at her blankly. 'Paul,' she said. 'Paul, Paul.'

'Poor cow.' Vanessa Taylor broke off a piece of chapatti and used it to wipe up what remained of the chicken massala. 'What kind of life's she got now?'

A good year they'd been doing this, Maddy and Vanessa, meeting up every week or so, when shifts allowed, a drink or two first and then a curry. A good goss and a natter. Bit of a bitching session, sometimes. Rules and regs. Pay. All that dyke or station-bike innuendo that was supposed to have been knocked on the head once and for all.

At twenty-nine, Vanessa was not only younger than Maddy but shorter and broader too, a figure on her and she didn't care who knew it. Before joining the force, she tried secretarial, then nursing, but not for long. Glorified bloody chambermaids, that's all you were. More blood and piss than the pubs in Kentish Town, which was where she was currently stationed. Three years as a uniformed constable and she still wasn't certain she'd stick with it.

Maddy had met her on a training course soon after moving down to London: 'Integrating Police Work with the Ethnic Community'. Vanessa sizing up the Asian community worker who was leading the afternoon session. 'Wouldn't mind integrating with that,' she'd winked. 'Given half the chance.' It turned out Vanessa lived no more than a few streets away from Maddy herself, Upper Holloway.

This evening, eyeing up one of the waiters whenever he passed their table, Vanessa reminded Maddy of that first occasion and asked her had she ever, you know, been with anyone Indian, Pakistani?

Maddy said she didn't think she had.

'I had this lad once…' Vanessa said, lowering her voice as she leaned forward. 'Student nurse at the hospital. Great big eyes.'

'Just the eyes?'

'Stop.' Laughing. 'Lovely-looking he was, beautiful skin.'

'You'll be telling me next you had him in the storeroom cupboard amongst the bandages and bedpans.'

'Better than that. Upstairs, on one of the empty beds. Ward was temporarily closed down because of the cuts.' Her face was flushed but it was probably due to the curry.

'What happened?' Maddy said.

'What d'you mean what happened?' Vanessa laughed again, louder than before. 'Too long ago to remember? Draw you a diagram if you like.'

'Not that, you idiot. I mean what happened to the bloke?'

'Oh, him. I dunno. Next week he'd moved on to Obstetrics. Good, though. Top Ten, I'd say.' She grinned. 'How about you? Top ten shags of all time.'

Maddy looked warily round, prepared to be embarrassed. 'Don't joke. I'd be scraping the barrel to come up with five or six.'

'You're kidding.'

'You should try getting married before you're twenty-one. Trims your sails a bit, I'm telling you.'

Vanessa crossed her knife and fork across her plate. 'You never were? Married that young?'

'Wasn't I?'

'How come you never said?'

'I don't know. Don't much like talking about it, I suppose.'

'Well, who was he? At least tell us that. What was his name?'

'Terry, his name was Terry. Okay? Satisfied? He was this bloke, older, a bit older, and I was just a kid, still living at home, and I thought he was God's gift. Now let's just leave it, right?'

'Right.' Vanessa shrugged and ordered two more bottles of Kingfisher. No point in pushing it further, she could see that. Not unless she fancied trolling along to the karaoke session in the pub later on her own.

'I keep thinking,' Maddy said a few minutes later, 'that poor little lad, Paul Draper's boy, growing up without a dad.'

'She'll find someone else, won't she? If she's any gumption. Kid'll not remember.'

Maddy shook her head. 'You really think it's that simple?'

'Yes. If you want it to be.'

'Sometimes I wonder,' Maddy said, 'if you know you're even born.'

'Fuck off,' Vanessa said, laughing. 'And pass us over that aubergine thingy if you're done with it.'

Shortly after midnight, the two women emerged from the raucous glitter of a late-night extension and set off, arm in arm, along the Holloway Road. Vanessa had talked Maddy into a duet version of 'Dancing Queen' which had been fine until Maddy had lost it two-thirds of the way through and faltered to a halt.
