Libby gave a sad smile. ‘Charlie always said she was clever.’
‘Well, when Alex got back they must have rehearsed what to do. Then she rang Valerie. Gave her the story about wanting to catch Charlie out, how he’d told her he was off to the NEC but she thought he was cheating on her, breaking their understanding and going to meet you.’
‘That wasn’t so far from the truth,’ Libby admitted.
‘The best lies run close,’ I said. ‘So, Valerie sees Alex when she calls for Heather. Alex then goes upstairs. He has his games console on. Heather makes a show of calling out goodbye to Charlie or maybe she even goes up and pretends to say goodbye to him. Some gesture to persuade Valerie that Charlie has not left the house, yet. Valerie never sets eyes on Charlie but she’s tricked into thinking he’s there. Then Heather and Valerie wait down the road in Valerie’s car. When Charlie’s car appears exiting the Carters’ drive they follow. It’s easy to keep up as he’s going so slowly; that’s because Alex is driving and he’s still a learner.’
Libby stared at me. ‘The opposite of Charlie, who drove like a maniac.’
‘Precisely.’
‘And she wouldn’t be able to tell it was him because of the tinted windows,’ Libby pointed out.
‘Yes, and don’t forget it was twilight. Now, the women didn’t want Charlie to notice them so Valerie even hung back at one point to let a car get between them. When Charlie’s car turns off towards the cottage, Heather plays the wounded wife. Valerie and Heather drive back home to the house in Hale. It sounds like Alex is still gaming upstairs, making a right racket. Heather complains to her friend and goes up and asks him to turn it down a bit. But he’s not there; it’s all a ploy. Meanwhile, Alex reaches the cottage and parks Charlie’s car in the drive. He locks the car. He has to go inside and leave the car keys. When they are later found there are no fingerprints on them so he must have wiped them clean.’
‘The knife?’ Libby asked me.
‘I don’t know,’ I admitted. ‘It was never found – he must have got rid of it.’
Libby shook her head, covering her mouth with her hand. Distressed, I imagined, at the harrowing thought of Alex in that gruesome situation.
‘Alex walks down the hill, passing Damien. He gets the bus back as close as he can then walks the rest of the way home. He sneaks upstairs and is there when Heather serves dinner. And they wait for the police to call.’
Libby sat there stunned, hands to her temples, gazing in the direction of Rowena, though I don’t think she was actually seeing her daughter or taking anything in from the room, from the present. Finally she moved her hands, straightened up and turned to me. ‘I don’t believe it,’ she said.
‘It’s hard to credit,’ I agreed.
‘No, not the cover-up: the fight. Charlie wasn’t like that, he was a very patient man. He never lost his temper.’
‘With you,’ I said.
‘In general. Honestly, the only time he got wound up was when he was driving.’
‘Maybe that was it,’ I suggested. ‘Alex was driving out there with him to get some practise. If Alex was going slowly, making mistakes, then Charlie would find it hard to keep calm. He’d be pretty wound up when they got there, then if Alex did something to make it worse…’
Libby shook her head. ‘No,’ she insisted, ‘Charlie would never have lost it like that. He’d never lay a finger on that boy.’
‘So, what Heather said about the fight…’
‘Bullshit,’ Libby said succinctly.
‘So was it something more sinister? Not an accident.’ But a boy that age. Where would such violence come from? ‘Alex – there was never any suggestion he was disturbed in any way?’ I asked her.
‘No. He was a bit shy. Sensitive. Stuck in his room, Charlie said, always on his computer. He didn’t have many friends; Charlie worried about that. Do you think Alex found out about us?’
‘It’s a helluva leap from that to picking up a knife.’ I imagined Alex, chaotic, confused, the blade in his hand, accusing his father, one fateful move. Talking to his mother, fleeing the scene, shock descending. Then the purgatory of driving back there. The cottage in the dark. Having to open that door. Feel the presence. Gag on the smell of death. The frantic scurry down the hill to the bus, passing Damien on his way up.
Ice froze in my veins; my heart grew heavy, a weight solid in my chest. ‘Oh, God.’
‘What?’ Libby sat forward, alert to the urgency in my voice.
‘He can’t have taken the bus home,’ I said. ‘They’re only every half hour and Damien had just got off the bus. Damien ran back to the bus stop after he’d stolen Charlie’s wallet. He waited for the next bus and he was alone at the bus stop.’
Libby shook her head, slowly. ‘More lies? What’s going on, Sal?’
‘I don’t know. Damien heard a car start up. Maybe Alex drove another car home.’
‘But you said he drove Charlie’s car; he couldn’t drive two cars.’
There was hammering on the front door.
‘I’m sorry,’ I said to Libby. ‘I won’t be a minute.’
It was Alex Carter, his clothes drenched with rain, his hair plastered to his head, shivering, looking younger than his years, hunted, haunted.
TWENTY
‘S he came to see you?’ he asked. His voice shook.
I swallowed. ‘Come in,’ I told him.
He stepped into the hall, his hands rammed in his pockets, shoulders hunched. Shivering still, his face red from the weather. ‘She won’t tell me what’s happening. But I know she came to see you: the number was on the phone.’
‘You should go home,’ I said gently, ‘talk to your mum.’
‘I asked her.’ He raised his voice in frustration. ‘She won’t talk to me! Is she in trouble?’
Oh, Alex. The naivety of the question was hard to fathom. He’d obviously no idea how much I already knew. I formulated a neutral reply; the last thing I wanted was him freaking out on me. ‘It’s likely that the conviction of Damien Beswick was unsound. The police will be examining new evidence; they may reopen the investigation.’
‘They can’t!’ he breathed, his eyes fixed on me.
I didn’t speak.
‘I can’t bear it,’ he said. He slid down the wall put his head in his hands, his knees bent up.
‘Shall I ring her, Alex?’ I asked. ‘She can come and pick you up?’
The reedy wail of Rowena crying came from below. Alex frowned, looking confused, and shook his head at my offer. ‘No,’ he mumbled. He circled his knees with his arms, his head buried.
‘It was an accident,’ I said.
He raised his head to look at me, his face twisted in disbelief. ‘She told you?’
I nodded.
‘Why?’ he said with horror. ‘Why did she tell you? We promised-’ he was too distraught to continue.
I rushed to calm him. ‘She wanted to explain, I think, that it had been an accident.’
‘She said no one would believe her,’ Alex whispered. His lips were swollen and red, the skin flaking. ‘That she’d be in prison for years. I don’t want her to go to prison!’
My skin crawled and adrenalin coursed through me like toxin. I crouched down. ‘For lying?’ I asked softly. I could feel my heart in my throat.
He stared at me, misery on his face, dull confusion. ‘No, for what she did.’
My tongue stuck to the roof of my mouth; I tried to swallow. ‘The accident?’
The stairs creaked and Libby appeared, Rowena in her arms. Alex glanced over at her, almost indifferent. I stood, crossing to her to try and prevent the encounter but I hadn’t reckoned on Libby’s determination.
‘Alex?’ she said.
‘Who are you?’
‘Libby.’
He froze, the colour draining from his face. ‘That was why they were arguing,’ he said, ‘because of you.’
‘Arguing?’ asked Libby.
‘If you hadn’t been-’
‘The accident,’ I interrupted, catching Libby’s eye, signalling this was important. ‘It was Heather.’
