She walked to the periphery of the crowd. What little talk there was amongst the on-lookers was conducted in low voices; one or two of the older women were crying. Though she peered over the heads of the spectators she could see nothing. Turning to a bearded man, whose child was perched on his shoulders, she asked what was going on. He didn't know. Somebody dead, he'd heard, but he wasn't certain.

'Anne-Marie?' she asked.

A woman in front of her turned and said: 'You know her?' almost awed, as if speaking of a loved one.

'A little,' Helen replied hesitantly. 'Can you tell me what's happened?'

The woman involuntarily put her hand to her mouth, as if to stop the words before they came. But here they were nevertheless: 'The child - 'she said.

'Kerry?'

'Somebody got into the house around the back. Slit his throat.'

Helen felt the sweat come again. In her mind's eye the newspapers rose and fell in Anne-Marie's yard.

'No,' she said.

'Just like that.'

She looked at the tragedian who was trying to sell her this obscenity, and said, 'No,' again. It defied belief; yet her denials could not silence the horrid comprehension she felt.

She turned her back on the woman and paddled her way out of the crowd. There would be nothing to see, she knew, and even if there had been she had no desire to look. These people - still emerging from their homes as the story spread - were exhibiting an appetite she was disgusted by. She was not of them; would never be of them. She wanted to slap every eager face into sense; wanted to say: 'It's pain and grief you're going to spy on. Why? Why?' But she had no courage left. Revulsion had drained her of all but the energy to wander away, leaving the crowd to its sport.

Trevor had come home. He did not attempt an explanation of his absence, but waited for her to cross-question him. When she failed to do so he sank into an easy bonhomie that was worse than his expectant silence. She was dimly aware that her disinterest was probably more unsettling for him than the histrionics he had been anticipating. She couldn't have cared less.

She tuned the radio to the local station, and listened for news. It came surely enough, confirming what the woman in the crowd had told her. Kerry Latimer was dead. Person or persons unknown had gained access to the house via the back yard and murdered the child while he played on the kitchen floor. A police spokesman mouthed the usual platitudes, describing Kerry's death as an 'unspeakable crime', and the miscreant as 'a dangerous and deeply disturbed individual'. For once, the rhetoric seemed justified, and the man's voice shook discernibly when he spoke of the scene that had confronted the officers in the kitchen of Anne-Marie's house.

'Why the radio?' Trevor casually inquired, when Helen had listened for news through three consecutive bulletins. She saw no point in withholding her experience at Spector Street from him; he would find out sooner or later. Coolly, she gave him a bald outline of what had happened at Butts' Court.

'This Anne-Marie is the woman you first met when you went to the estate; am I right?'

She nodded, hoping he wouldn't ask her too many questions. Tears were close, and she had no intention of breaking down in front of him.

'So you were right,' he said.

'Right?'

'About the place having a maniac.'

'No,' she said. 'No.'

'But the kid - '

She got up and stood at the window, looking down two storeys into the darkened street below. Why did she feel the need to reject the conspiracy theory so urgently?; why was she now praying that Purcell had been right, and that all she'd been told had been lies? She went back and back to the way Anne-Marie had been when she'd visited her that morning: pale, jittery; expectant. She had been like a woman anticipating some arrival, hadn't she?, eager to shoo unwanted visitors away so that she could turn back to the business of waiting. But waiting for what, or whom? Was it possible that Anne-Marie actually knew the murderer? Had perhaps invited him into the house?

'I hope they find the bastard,' she said, still watching the street.

'They will,' Trevor replied. 'A baby-murderer, for Christ's sake. They'll make it a high priority.'

A man appeared at the corner of the street, turned, and whistled. A large Alsatian came to heel, and the two set off down towards the Cathedral.

'The dog,' Helen murmured.

'What?'

She had forgotten the dog in all that had followed. Now the shock she'd felt as it had leapt at the window shook her again.

'What dog?' Trevor pressed.

'I went back to the flat today - where I took the pictures of the graffiti. There was a dog in there. Locked in.'

'So?'

'It'll starve. Nobody knows it's there.'

'How do you know it wasn't locked in to kennel it?'

'It was making such a noise - she said.

'Dogs bark,' Trevor replied. 'That's all they're good for.'

'No - ' she said very quietly, remembering the noises through the boarded window. 'It didn't bark...'

'Forget the dog,' Trevor said. 'And the child. There's nothing you can do about it. You were just passing through.'

His words only echoed her own thoughts of earlier in the day, but somehow - for reasons that she could find no words to convey - that conviction had decayed in the last hours. She was not just passing through. Nobody ever just passed through; experience always left its mark. Sometimes it merely scratched; on occasion it took off limbs. She did not know the extent of her present wounding, but she knew it more profound than she yet understood, and it made her afraid.

'We're out of booze,' she said, emptying the last dribble of whisky into her tumbler.

Trevor seemed pleased to have a reason to be accommodating. 'I'll go out, shall I?' he said. 'Get a bottle or two?'

'Sure,' she replied. 'If you like.'

He was gone only half an hour; she would have liked him to have been longer. She didn't want to talk, only to sit and think through the unease in her belly. Though Trevor had dismissed her concern for the dog - and perhaps justifiably so - she couldn't help but go back to the locked maisonette in her mind's eye: to picture again the raging face on the bedroom wall, and hear the animal's muffled growl as it pawed the boards over the window. Whatever Trevor had said, she didn't believe the place was being used as a makeshift kennel. No, the dog was imprisoned in there, no doubt of it, running round and round, driven, in its desperation, to eat its own faeces, growing more insane with every hour that passed. She became afraid that somebody - kids maybe, looking for more tinder for their bonfire -would break into the place, ignorant of what it contained. It wasn't that she feared for the intruders' safety, but that the dog, once liberated, would come for her. It would know where she was (so her drunken head construed) and come sniffing her out.

Trevor returned with the whisky, and they drank together until the early hours, when her stomach revolted. She took refuge in the toilet - Trevor outside asking her if she needed anything, her telling him weakly to leave her alone. When, an hour later, she emerged, he had gone to bed. She did not join him, but lay down on the sofa and dozed through until dawn.

The murder was news. The next morning it made all the tabloids as a front page splash, and found prominent positions in the heavyweights too. There were photographs of the stricken mother being led from the house, and others, blurred but potent, taken over the back yard wall and through the open kitchen door. Was that blood on the floor, or shadow?

Helen did not bother to read the articles - her aching head rebelled at the thought - but Trevor, who had brought the newspapers in, was eager to talk. She couldn't work out if this was further peacemaking on his part, or a genuine interest in the issue.
