Behind her, a noise. She turned so quickly she almost tripped over the blanket-strewn mattress.

'Who - ?'

At the other end of the gullet, in the living-room, was a scab-kneed boy of six or seven. He stared at Helen, eyes glittering in the half-light, as if waiting for a cue.

'Yes?' she said.

'Anne-Marie says do you want a cup of tea?' he declared without pause or intonation.

Her conversation with the woman seemed hours past. She was grateful for the invitation however. The damp in the maisonette had chilled her.

'Yes...' she said to the boy. 'Yes please.'

The child didn't move, but simply stared on at her.

'Are you going to lead the way?' she asked him.

'If you want,' he replied, unable to raise a trace of enthusiasm.

'I'd like that.'

'You taking photographs?' he asked.

'Yes. Yes, I am. But not in here.' 'Why not?'

'It's too dark,' she told him.

'Don't it work in the dark?' he wanted to know.

'No.'

The boy nodded at this, as if the information somehow fitted well into his scheme of things, and about turned without another word, clearly expecting Helen to follow.

If she had been taciturn in the street, Anne-Marie was anything but in the privacy of her own kitchen. Gone was the guarded curiosity, to be replaced by a stream of lively chatter and a constant scurrying between half a dozen minor domestic tasks, like a juggler keeping several plates spinning simultaneously. Helen watched this balancing act with some admiration; her own domestic skills were negligible. At last, the meandering conversation turned back to the subject that had brought Helen here.

'Them photographs,' Anne-Marie said, 'why'd you want to take them?'

'I'm writing about graffiti. The photos will illustrate my thesis.'

'It's not very pretty.'

'No, you're right, it isn't. But I find it interesting.'

Anne-Marie shook her head. 'I hate the whole estate,' she said. 'It's not safe here. People getting robbed on their own doorsteps. Kids setting fire to the rubbish day in, day out. Last summer we had the fire brigade here two, three times a day, 'til they sealed them chutes off. Now people just dump the bags in the passageways, and that attracts rats.'

'Do you live here alone?'

'Yes,' she said, 'since Davey walked out.'

'That your husband?'

'He was Kerry's father, but we weren't never married. We lived together two years, you know. We had some good times. Then he just upped and went off one day when I was at me Main's with Kerry.' She peered into her tea-cup. 'I'm better off without him,' she said. 'But you get scared sometimes. Want some more tea?'

'I don't think I've got time.'

'Just a cup,' Anne-Marie said, already up and unplugging the electric kettle to take it across for a re-fill. As she was about to turn on the tap she saw something on the draining board, and drove her thumb down, grinding it out. 'Got you, you bugger,' she said, then turned to Helen: 'We got these bloody ants.'

'Ants?'

'Whole estate's infected. From Egypt, they are: pharoah ants, they're called. Little brown sods. They breed in the central heating ducts, you see; that way they get into all the flats. Place is plagued with them.'

This unlikely exoticism (ants from Egypt?) struck Helen as comical, but she said nothing. Anne-Marie was staring out of the kitchen window and into the back-yard.

'You should tell them - ' she said, though Helen wasn't certain whom she was being instructed to tell, 'tell them that ordinary people can't even walk the streets any longer - 'Is it really so bad?' Helen said, frankly tiring of this catalogue of misfortunes.

Anne-Marie turned from the sink and looked at her hard.

We've had murders here,' she said.

'Really?'

'We had one in the summer. An old man he was, from Ruskin. That's just next door. I didn't know him, but he was a friend of the sister of the woman next door. I forget his name.'

'And he was murdered?'

'Cut to ribbons in his own front room. They didn't find him for almost a week.'

'What about his neighbours? Didn't they notice his absence?'

Anne-Marie shrugged, as if the most important pieces of information - the murder and the man's isolation - had been exchanged, and any further enquiries into the problem were irrelevant. But Helen pressed the point.

'Seems strange to me,' she said.

Anne-Marie plugged in the filled kettle. 'Well, it happened,' she replied, unmoved.

'I'm not saying it didn't, I just - '

'His eyes had been taken out,' she said, before Helen could voice any further doubts.

Helen winced. 'No,' she said, under her breath.

'That's the truth,' Anne-Marie said. 'And that wasn't all'd been done to him.' She paused, for effect, then went on: 'You wonder what kind of person's capable of doing things like that, don't you? You wonder.' Helen nodded. She was thinking precisely the same thing.

'Did they ever find the man responsible?'

Anne-Marie snorted her disparagement. 'Police don't give a damn what happens here. They keep off the estate as much as possible. When they do patrol all they do is pick up kids for getting drunk and that. They're afraid, you see. That's why they keep clear.'

'Of this killer?'

'Maybe,' Anne-Marie replied. 'Then: He had a hook.'

'A hook?'

'The man what done it. He had a hook, like Jack the Ripper.'

Helen was no expert on murder, but she felt certain that the Ripper hadn't boasted a hook. It seemed churlish to question the truth of Anne-Marie's story however; though she silently wondered how much of this - the eyes taken out, the body rotting in the flat, the hook - was elaboration. The most scrupulous of reporters was surely tempted to embellish a story once in a while.

Anne-Marie had poured herself another cup of tea, and was about to do the same for her guest.

'No thank you,' Helen said, 'I really should go.'

'You married?' Anne-Marie asked, out of the blue.

'Yes. To a lecturer from the University.'

'What's his name?'

'Trevor.'

Anne-Marie put two heaped spoonfuls of sugar into her cup of tea. 'Will you be coming back?' she asked.

'Yes, I hope to. Later in the week. I want to take some photographs of the pictures in the maisonette across the court.'

'Well, call in.

'I shall. And thank you for your help.'

'That's all right,' Anne-Marie replied. 'You've got to tell somebody, haven't you?'

'The man apparently had a hook instead of a hand.'

Trevor looked up from his plate of tagliatelle con prosciutto.

'Beg your pardon?'

Helen had been at pains to keep her recounting of this story as uncoloured by her own response as she could. She was interested to know what Trevor would make of it, and she knew that if she once signalled her own stance he would instinctively take an opposing view out of plain bloody-mindedness.

'He had a hook,' she repeated, without inflexion.

Trevor put down his fork, and plucked at his nose, sniffing. 'I didn't read anything about this,' he said.

'You don't look at the local press,' Helen returned. 'Neither of us do. Maybe it never made any of the nationals.'

'"Geriatric Murdered By Hook-Handed Maniac"?' Trevor said, savouring the hyperbole. 'I would have thought it very newsworthy. When was all of this supposed to have happened?'

'Sometime last summer. Maybe we were in Ireland.'

'Maybe,' said Trevor, taking up his fork again. Bending to his food, the polished lens of his spectacles reflected only the plate of pasta and chopped ham in front of him, not his eyes.

'Why do you say maybe?' Helen prodded.

'It doesn't sound quite right,' he said. 'In fact it sounds bloody preposterous.'

'You don't believe it?' Helen said.

Trevor looked up from his food, tongue rescuing a speck of tagliatelle from the corner of his mouth. His face had relaxed into that non-committal expression of his - the same face he wore, no doubt, when listening to his students. 'Do you believe it?' he asked Helen. It was a favourite time-gaining device of his, another seminar trick, to question the questioner.
