‘Look, I don’t know why you’re here but I really can’t help you. I think you should …’
‘What are you all frightened of?’ Kim asked, not moving an inch.
‘Excuse me …’
She hadn’t meant the question to sound so direct, but now it was out she had to stick with it.
‘Your daughter is not used to visitors, is she?’
Sarah couldn’t quite meet her gaze.
‘We’re just private, that’s all. Now, if you don’t mind …’
Kim pushed the chair out and looked around. She assessed the collection of photographs. The three of them stood on the bridge she’d rode across where it straddled the river Dee. The child in a horse-drawn barge. The child and her father on the steam railway that ran alongside the river.
Kim decided on a different approach. ‘Yeah, can’t wait to leave. Bloody horrible place to …’
‘It’s a beautiful … ’
‘So, why are you moving, Mrs Lewis?’
Sarah’s hands balled into fists in her pockets.
‘It’s Nick’s job, he’s a …’
Kim waited for a response but it was clear that Sarah had realised her blunder. She hadn’t thought quickly enough of a profession so was left sounding like a woman who didn’t know what her husband did for a living.
‘Mrs Lewis … Sarah, one of my team commented that army wives don’t move around as much as you. What are you running from?’
Sarah moved towards the front door but her step was far from steady.
‘I’d really like you to leave now. I have no information that can help you.’
Kim followed her through the lounge.
‘I don’t believe you. You’re terrified and your whole family is fearful of something. Your first question was to ask me if she was dead. I saw your anxiety when I confirmed she was not. Why won’t you tell me …?’
‘Please, just leave.’
The woman’s hand trembled on the door.
‘Sarah, what are you afraid of?’
‘Just go.’
‘Why won’t you just talk to …’
‘Because if I speak to you about her, she’ll know.’
Silence fell between them.
Kim realised this was not the same Sarah who had opened the door. That woman had been hostile, then hopeful to anxious but conversation regarding her sister had reduced her to a battle-weary shell.
‘Sarah … ’
‘I can’t,’ she said, staring at the ground. ‘You don’t understand.’
‘You’re right. But I’d like to. I want to get inside your sister’s head.’
Sarah shook her head. ‘No, you really don’t. It’s not a nice place to be.’
‘I don’t know what power she has over you but is this really what you want? Do you want to teach your daughter to run?’
Sarah met her gaze, her eyes blazing at the mention of her child.
‘She doesn’t even have friends, does she? You don’t stay anywhere long enough for her to bond. How old is she … six … seven?’
‘Six.’
‘She needs to settle, so why can’t you stay?’
‘Because she found us.’
‘Sarah, I want to help you but you’ve got to give me something.’
Sarah smiled. ‘No one can help me. I’ve never spoken to anyone who …’
‘You’ve never spoken to me,’ Kim said, stepping away from the door. ‘I have suspicions about her behaviour and if I’m right I won’t rest until she’s caught.’
Sarah eyed her with interest. ‘What’s going on with the two of you?’
Kim smiled. ‘Hey, I asked first.’
Sarah considered for a long moment. She took a deep breath and closed the door.
‘If I show you something, will you leave me in peace?’
Kim nodded and followed her back to the kitchen. Sarah nodded for Kim to sit back down.
Sarah reached into the cutlery drawer and retrieved an envelope. ‘This is why.’
She handed the letter to Kim. ‘Read it.’
Kim unfolded the single sheet of paper, read it and then read it again, before shrugging her shoulders. If this was the best she could get on Alexandra Thorne she was well and truly stuffed.
‘It seems like a perfectly natural letter from an older sister.’
‘I’ve lived here with my husband and daughter for nine months. That’s how long it took her to find me this time.’
‘This time?’
‘I’ve moved my family five times in seven years to hide my child from this woman and every time she finds me. Read the letter again. Note how she mentions exactly where the house is, the location of Maddie’s school and even my daughter’s new haircut. She’s taunting me. Playing on my fears – because she knows exactly what I’ll do next.’
Kim read the letter for a third time, putting the Alex she suspected behind the words. There was menace in every sentence.
‘But why do you run?’ Kim asked.
‘You don’t know her as well as I’d hoped.’
Sarah took back the letter and sighed heavily.
‘My sister is a sociopath. You already know that she is a very attractive, enigmatic person. She’s intelligent and charming. She is also ruthless and completely without conscience. She is a dangerous person, who will stop at nothing to get what she wants.’
Sarah folded the letter and then stared at it. ‘Quite simply, she has no ability to feel any connection with another living thing.’
‘What makes you think your sister is a sociopath?’
‘Because she has never had an emotional attachment to anything or anyone in her life.’
‘What about her husband and two boys?’ Kim asked.
Sarah frowned. ‘She’s never been married and certainly has no children. Sociopaths do marry and have children as trophies and a cover but there’s no emotional connection.’
Kim raised an eyebrow.
Sarah smiled. ‘You see? You can’t believe that someone might treat children as a status symbol like a new car or a bigger house, and that is what the sociopath relies on. People like us can’t understand their motives and so make excuses for them. It’s how they stay hidden.’
Sarah shook her head sadly. ‘And that is why she will never be stopped.’
‘She told me you were dead,’ Kim offered.
Sarah showed no surprise. ‘I wish to her I was. Perhaps then she would leave me alone.’
The woman offered Kim a look that was filled with sad resignation. This was her life and no one could change it. She’d spent years trying to outrun her sister and that was the way it would stay.
Sarah glanced towards the front door. She had shared the letters and now it was time for Kim to leave.
‘Sarah, I think she’s using her patients for experimental purposes,’ Kim blurted out. ‘And I’d like to stop her. I’d like to put your sister behind bars.’
Sarah tipped her head to the side and Kim detected a glimmer of interest.
‘Come on, Sarah,’ Kim pleaded. ‘Help me give you back your life.’
Kim watched her struggle with the indecision of actually placing that trust with someone she didn’t even know.
She hoped she had said enough.
Sarah offered her a watery smile. ‘Detective Inspector, I think we need coffee.’
FORTY-FOUR
Two cups of steaming coffee sat on the table between them.
‘You have to understand this isn’t easy for me,’ Sarah said, resting her elbows on the table. ‘I’ve known my whole life that there’s something missing from my sister but no one ever believed me.’ She shrugged. ‘It’s why I run.’
Kim got it. Her own suspicions were being disregarded by her colleagues and boss.
‘You’re the first person that doesn’t think I’m completely insane,’ Kim observed.
‘Ditto,’ Sarah added, wryly.
‘So, do you think it’s possible … what I said?’
‘No, I think it’s probable.’ Sarah cupped her hands around the coffee mug and shuddered. ‘I remember when I had just turned five and I noticed Alex was spending a lot of time in her bedroom, only leaving for meals and school. One night, Alex woke me excitedly clapping her hands. She dragged me from my bed to her room, sat me on the edge of her bed and removed a tall encyclopaedia from in front of the hamster cage.
